Mounting Using the DIN Bracket
If you are unsure about how to install your UH8055S in your vehicle using the DIN bracket, consult your automobile manufacturer, dealer, or a qualified installer. The DIN bracket is made up of a sleeve and a frame.
Before installing, confirm that your UH8055S fits in the desired mounting area and you have all the necessary materials to complete the task.

Installing the DIN Bracket
- Remove the 4 front mounting screws to separate the front frame from the DIN sleeve.
- Install the DIN sleeve into the DIN slot of your dashboard and secure it by bending the top and bottom folding tabs.
- Slide UH8055S into the front frame. Ensure the threaded holes on UH8055S line up with holes on the front frame.
- Secure UH8055S onto the front frame using 4 pieces of 6mm screws.
- Attach the DC power leads to UH8055S and your vehicle. RED goes to a positive (+) connection on your fuse block while BLACK connects to the vehicle chassis ground (-).
- Attach the antenna cable, rear MIC and rear speaker to the back of UH8055S if using.
- Make sure all the connections are routed away from any potentially pinching or slicing sheet metal.
- Slide the front frame (with UH8055S attached and all cable connections done) back into the DIN sleeve and secure it using 4 front mounting screws.

If you plan to use the Rear MIC Jack or connect an external speaker at a later time, expect to remove the unit for ease of making those connections.
Connecting the Microphone


Front MIC Jack
Push the MIC plug at the end of the microphone into the MIC jack until the connection locks into place. Gently tug the MIC cord to test that the connection is locked. Use the Front MIC Jack cover which is threaded onto the MIC cord to seal the MIC jack entry from dust.
Disconnecting the MIC from the Front MIC Jack
Pull away the threaded rubber collar and move it down along the cord. Using the flat blade of a screwdriver or similar object carefully press the lock tab at the bottom of the MIC plug and push it upwards. At the same time tug on the MIC cord to draw back the MIC plug.
Rear MIC Jack

![Press and hold VOLT/WR control at the base or the [POWER] button on the optional Remote SPK/MIC.](/content/2026/05/1056115/images/1e3ce342dd984c1c1c451964a16fddfa4e839d1bcefcac01962093fa3a536f0e.jpg)

Low-Voltage/High-Voltage Alert
The UH8055S can operate on 12VDC (13.8V) or 24VDC (27.6V) power supply, with the range between 10.2VDC to 28.8VDC.

If the power supply voltage exceeds 28.8VDC, an alert tone sounds and HI DC flashes for 5 seconds. The power source must not exceed 32VDC otherwise permanent damage may occur to your radio, which may not be covered by the manufacturer's warranty.
If the input voltage falls below 10.2VDC, LO DC flashes for 5 seconds. The power turns off automatically if voltage falls below 9.0VDC.
Switch your UH8055S OFF and disconnect it from the power source, before locating the cause of the power supply problem.
Setting the Volume
Turn the volume control at the base or press the volume ▲ on the side of the optional Remote SPK/MIC to adjust the volume. The base volume is composed of 42 steps and the optional Remote SPK/MIC is 7 steps.
See Volume Sync on page 32 to synchronize the volume control when the optional Remote SPK/MIC is connected.
Setting the Manual Squelch
Turn the outer ring of the SQ control at the base to adjust the Squelch.

You must select a channel which is not in use before setting the SQUELCH control. (see p.19 for "Selecting a Channel").

Think of the squelch control as a gate. If you turn Squelch fully clockwise it raises the 'Squelch gate' so high that no signals get through.

If you turn Squelch fully counter clockwise it lowers the 'Squelch gate' so low that noise gets through.

To set the 'Squelch Gate' to the desired level, turn the squelch knob counterclockwise until you hear noise. Then carefully turn the Squelch knob clockwise until the noise fades. Now only strong signals get through.
Setting the Auto Squelch Level
The Auto Squelch feature is available only when the optional Remote SPK/MIC is connected. It has an Off setting and 5 preset squelch levels:
SQL-4 - minimum sensitivity (max/tight squelch)
SQL-3 - medium sensitivity
SQL-2 - moderate sensitivity
SQL-1 - max sensitivity (min squelch)
SQL-0 - Squelch open (monitor)
SQL-OFF
(SQ Volume on the BASE can be activated)

- Press [SQL]. The squelch setting flashes.
- Press ▲ / ▼ on the optional Remote SPK/MIC to change the setting.

- If SQL-0 (squelch open) is selected then MON (monitor) icon flashes.
- If SQL-4 (tight squelch) is selected then SQT icon flashes.
-
Selecting tight squelch mode may prevent the reception of weak signals.
• High noise areas may still break the squelch. -
Press [SQL] to store the setting.
Selecting a Channel
Turn the Rotary Channel Selector at the base or press ▲ / ▼ on the optional Remote SPK/MIC to select the desired channel.

Press and hold [DUAL]. DUAL icon appears and two beeps will sound.
To cancel DUAL Watch press and hold [DUAL]. DUAL icon disappears.


- Every 1.5 seconds the Instant channel is monitored for 100msec.
- Dual watch function stops temporarily when receiving a signal.
- Dual watch function is invalid in Scan mode.
Using Repeater Channels
UHF CB repeaters are used to retransmit or relay your signal. Repeaters will extend the range of your radio and overcome the shielding effect caused by solid obstructions. In normal Simplex operation, your radio transmits on one particular frequency and receives on that same frequency.
If there is a barrier that partially blocks your transmitted signal, the probability of another radio receiving the signal is very slim. Hills, tall buildings, metallic structures,...etc tend to act as a screen between radios.

Standard Operation without the aid of a Repeater station.
Operation with the aid of a Repeater Station (Duplex).
The signal coming from your radio is received by the Repeater Station and the re-transmitted at the same time on another channel. This operation is called "Duplexing".
For example,
CH01 on Duplex Mode will Receive on CH01 but Transmit on CH31
CH02 on Duplex Mode will Receive on CH02 but Transmit on CH32 etc...
If you transmit on CH01 Duplex mode, you are actually transmitting on CH31 the repeater station down-converts your signal and retransmits on CH01.

Operating the UHF CB Radio in Duplex Mode
For this example we are adopting CH01 as the channel being used in your area for repeater use.
- Press [MENU] on the base. The duplex setting flashes.
- Turn the Rotary Channel Selector on the base to change the setting between ON or OFF (standard channel numbering).
- Press and hold [MENU] to save & exit from the menu mode.
DUP icon displays when a selected channel is set to Duplex mode.


- Only channels 01 - 08, and channels 41 - 48 are available for Duplex.
- Check with your local Retailer for information on available repeaters.
- If a button is not pressed within 10 seconds the UHF CB Radio will automatically exit the Menu Mode.
Scanning
The UH8055S' Scanning feature allows you to search for active channels automatically. There are 3 scanning modes;
Open Scan (OS),
Group Scan (GS) and
Master Scan (M.SCN) (a special case of Group Scan).
During SCAN the UH8055S only checks channels or frequencies that are in the SCAN Memory, which are indicated by the M (memory) icon. The UH8055S maintains two SCAN Memories; one for Open Scan (OS) mode and the other for Group Scan (GS mode, to give you flexibility and allow you to use the radio more effectively.

Group Scan and Master Scan modes share the same SCAN Memory.
Furthermore, any combination of the three channel groups can be scanned by pressing [POLICE] during scan to select the desired channel groups.
- Press [SCAN] to start Scanning.
- The SCAN icon appears.
- The scan direction can be changed at any time by rotating the Channel knob on the base.
- Press [SCAN] to stop Scanning.
Add/Remove Channels from SCAN Memory
Select OS Scanning Mode. Select the channel you want to store.
Press and hold [MEM]. MEM icon appears and two beep tones sound. To remove the channel from SCAN memory, press and hold [MEM] once more.
The MEM icon disappears.
MASTER SCAN Mode
MASTER SCAN is the default scan mode and is enabled to allow continual communication across congested channels.
Master Scan scans channels stored into GS Memory and only opens the squelch for signals with the correct subcode (CTCSS or DCS tone).
To achieve this, all radios in your group must have the same channels in GS memory (group channels) and use the same Subcode (CTCSS or DCS tone).
By scanning only group channels, radios in the network will be able to detect and receive group transmissions- continual communication without interruption. When transmitting in this mode, the radio switches to an unused group channel if it detects another signal with no code, or the wrong code, on the channel last used by the group. In this way, all group users will be able to have continual communication to or from other users.
CH09-CH20 are stored into GS Memory and CTCSS01 is set for MASTER SCAN Subcode by default. The GS memory can be changed, channel by channel, if desired - but for Master Scan to work effectively each radio in the group must have the same channels in its GS memory.
To add/remove channels from GS SCAN Memory, refer the section above.


RX only Channels (CH22, CH23, CH61, CH62 and CH63), User Programmable RX Channels (CH81 to CH180) and Police or Fire (& Ambulance) channels group will not be included in MASTER SCAN Mode even though stored into GS Memory Also channels for which Duplex Setting are On will be skipped in MASTER SCAN Mode.
To select MASTER SCAN Mode:
- Press [MENU] four times.
The M.SCAN setting flashes.
- Turn the Rotary Channel Selector to change the setting.
oF: Master Scan is OFF - Scan mode becomes Open Scan or Group Scan depending on GS option setting
on: Master Scan is ON with the current GS channel memory. Open/Group Scan is disabled.
P1: Master Scan is ON with loading CH09-20 in GS.
P2: Master Scan is ON with loading CH21-30, 39, 40 in GS.
P3: Master Scan is ON with loading CH49-60 in GS.
P4: Master Scan is ON with loading CH61-70, 79, 80 in GS.



- Press [MENU] one more time.
- Turn the Rotary Channel Selector to select the desired Subcode (CTCSS or DCS).


- Press and hold the [MENU] to save and exit from the Menu Mode.

If a button is not pressed within 10 seconds the UHF CB Radio will automatically exit the Menu Mode.
Open Scan (OS) Mode
All UHF-CB, user-programmed extra RX channels, Police and Fire & Ambulance frequencies have been added to the OS SCAN Memory for convenience. To add/remove channels from OS SCAN Memory, refer to p.25.
Allows continuous scanning of all selected channels. If an active channel is found, scanning will stop on that channel. If the received signal ceases, the unit will wait 3 seconds for the signal to return, otherwise scanning resumes.
After transmission in scan mode, the unit will wait 20 seconds for the signal to return, otherwise scanning resumes.
To deactivate SCAN, press [SCAN].


NOTE
If SCAN is deactivated while on an active channel, the UH8055S will stay on that active channel. If no channels are active, the UH8055S will reinstate the starting channel.

NOTE
OS Mode is indicated by the absence of the GS icon.
Group Scan (GS) Mode
GS Mode has CH09 to CH20 in the SCAN Memory by default. Channels must be stored to the GS SCAN Memory before group scan can start. To add/remove channels from GS SCAN Memory, refer to p.25.
Includes the accessory feature Priority Watch which allows you to monitor the Instant Priority Channel while scanning (see p.20 for setting Instant Priority Channel and p.29 to turn on Priority Watch).

GS Scanning checks the Instant Priority Channel for activity regularly when Priority Watch is ON.
If the Priority Channel becomes active the radio will stay on that channel for as long as the signal is present. If the received signal ceases, Priority Scanning continues after 3 seconds.
If scanning stops on a channel which is not a Priority Channel, UHF CB Radio will continue monitoring the Priority Channel for activity while listening to the active one.
To select GS Scan Mode:
- Press [MENU] three times. The GS setting flashes.
- Turn the Rotary Channel Selector to change the setting between ON and OFF.
- Press and hold [MENU] to save & exit from the menu mode.

NOTE
If a button is not pressed within 10 seconds the UHF CB Radio will automatically exit the Menu Mode.

Close Call™ RF Capture
The Close Call RF Capture feature sets the UH8055S so it detects and then displays the frequency of a nearby strong radio transmission. Close Call RF capture works great for finding frequencies at venues such as malls and sporting events.
Close Call RF Capture doesn't tune to a frequency to check for a transmission, instead it directly detects the presence of a strong, nearby signal and instantly tunes to the source's frequency. The UH8055S only tries to find Close Call transmissions from 400-520 MHz.

- Close Call RF capture works well for locating the source of strong local transmissions such as mobile and handheld two-way radios in areas with no other strong transmission sources. However, if you are in an area with many transmission sources (such as pager radio transmitters, multi-use radio towers, traffic control devices, etc.), Close Call RF capture might not find the transmission you are searching for, or it might find a transmission other than the one you are searching for.
- Close Call works better with some types of transmissions than others. It might not correctly display frequency information for transmitters using a highly directive antenna (such as an amateur radio beam antenna), if there are many transmitters operating at the same time in the same area, or if the transmitter is a broadcast television station.
Using Close Call
To start or stop Close Call RF Capture:
1. Press [CLOSE CALL].
The C-C icon appears and C.CALL is displayed when Close Call RF Capture mode.
When a signal is found a confirmation chirp is sounded and CC FOUND flashes on the display. Press any key (except CLOSE CALL key) when CC FOUND is displayed to show the frequency. The signal strength is also displayed with CC FOUND display.
Lockout an Undesired Frequency
If the signal frequency is undesired (for instance it is a data channel) then the frequency can be added to the lockout list and ignored in future.
- First press [HOLD] to stay on that frequency.
- And then press and hold [HOLD] to lockout that frequency and resume Close Call RF Capture mode.
Unlock a Locked out frequency
- The locked out frequencies can be reviewed by pressing [MENU] while you are in Close Call mode.
LO displays and the lowest frequency in the lockout list flashes.
- Rotate the Channel knob to view other frequencies in the list.
- Press and hold [HOLD] to unlock the currently displayed frequency.
Two beeps sound.
- Press [MENU] to resume Close Call RF Capture mode.

NOTE
- Close Call RF Capture feature is separate to and cannot be operated at the same time as SCAN or normal receive mode.
Selective Calling
Selective Calling (Selcall) is a special Sequential Tone Squelch System that allows the user to receive/transmit calls selectively from/to an individual or group, on a shared busy channel. Therefore Selcall is a group feature used by groups with similarly set up radios.
The UH8055S has a Selective Calling system. Exceptional features, like 10 Selcall ID Memories, Receiver Quieting, Tone Squelch Scanning, Tone and Group Calling make the UH8055S superior to other transceivers in its class.
Receiver Quieting (Tone Squelch)
When activated on individual UHF-CB channels (except for emergency CH05 and CH35), it automatically mutes the receiver audio circuit of the radio. It will stay in this Quiet mode as long as the Selcall tone code (Selcall ID) required to open the muting circuit is not received.
Call Alarm
When a received code matches to your Selcall ID, an alarm (CA Alert) will be emitted informing you that a caller is on the channel.
Tone Squelch Scanning
Scans only tone squelched Channels.
Tone Calling
Allows you to selectively call another radio. Up to 10 Selcall IDs can be stored for frequently called radios.
Group Calling Capability
Transmits Group Calls.
Programming the Selcall ID for your UH8055S
The radio Selcall ID is the ID other users will identify as being your radio. It is set in the Selcall settings menu as follows:
- Power Off the UH8055S.
- Press and hold [POWER] and [MENU]. The UH8055S should turn on in the SELCALL Menu selection state (no tone will sound). Cd displays to indicate the Call ID setting (factory default ID is 00000).
- Press [SCAN] to begin the frequency edit. The 5th digit of the ID flashes.
- Use ◀ or ▶ to shift between digits. A 6th digit (for 6 tone Selcall) is available and indicated by a ‘_’.
- Turn the Rotary Channel Selector to select the desired ID.
- Press and hold [ENTER] to exit the setting mode.
- Press and hold [ENTER] again to exit programming mode. A long confirmation tone sounds.
Storing Selcall IDs of other users to the ID Memory
- Press and hold [CALL/SELCALL]. The Selcall ID memory will open.
- Turn the Rotary Channel Selector to select the desired memory slot to edit.

- Up to 10 ID memories can be stored.
-
If you expect to make calls to radios not stored in the ID memory then leave memory ID 1 blank for manual ID entry at the time of the call.
-
Press [SCAN] to begin the ID edit. The 5th digit of the ID flashes.
-
Use ◀ or ▶ to shift between digits. A 6th digit (for 6 tone Selcall) is available and indicated by a ‘_’.
-
Turn the Rotary Channel Selector to select the desired ID.
-
When desired ID is entered press [SCAN] to move to Alpha Tag selection. A cursor flashes in the 1st alpha position. The default aplha tag is blank - displays as No Name. If you do not wish to name the ID then skip to step 9.
-
Turn the Rotary Channel Selector to select the desired alpha character.
-
Use ◀ or ▶ to shift between cursor positions.
-
When finished press [SCAN]. A confirmation tone sounds to indicate the ID is programmed. The memory number flashes to enable selection for programming of next memory if desired.
-
Press and hold [ENTER], or wait for 10sec, to exit programming mode.
Tone Calling (Making a Selcall Call)
Tone Calling allows you to selectively call other radios.
For convenience, the Selcall ID of the radio you are going to call should be in the Selcall ID memory (see Storing Selcall IDs of other users to the ID Memory p.40). If not then the Selcall ID can be manually entered for this call.
To Call:
- Select the channel that you and your group agreed to use for Selective Calling.
- Press and hold [CALL/SELCALL] for 2 seconds. A double beep tone will sound and the last stored ID or last transmitted ID will be displayed.
- Turn the Rotary Channel Selector to select the desired Selcall ID.
If the desired Selcall ID is not stored in the ID memory you can manually enter the ID as follows;
a) Press [SCAN] to begin ID edit. The 5th digit of the ID flashes.
b) Use ◀ or ▶ to shift between digits. A 6th digit (for 6 tone Selcall) is available and indicated by a ‘_’.
c) Turn the Rotary Channel Selector to select the desired ID.
- Press [CALL/SELCALL] to transmit the Selcall. CAL will display when transmitting the Selcall.
An acknowledge tone coming from the called radio will be received if you have successfully made contact. The acknowledge tone for the UH8055S is a succession of three low tone beeps.
Receiver Quiet (TSQ) Mode
Puts the receiver in the QUIET mode (also known as the Tone Squelch (TSQ) mode) for the selected channel. When activated, the transceiver prevents any unwanted conversations in the channel from being heard unless the call is specifically directed to you and the Selcall ID required to open the QUIET condition has been received.

Under this condition, PTT is temporarily disabled. If you wish to use the same Channel for normal communication, simply remove the channel from QUIET mode.
To Activate/Deactivate Tone Squelch (TSQ) on a Channel
- Rotate the Channel knob to select the channel you want to put in or take out of 'QUIET' mode.
- Press and hold [TSQ] for 2 seconds. Two beeps will sound and the TSQ icon appears on or disappears from the LCD display.
Receiving a Selcall
While in TSQ mode, when UH8055S receives a code matching your Selcall ID, it will perform the following operations:
a) Automatically responds to the caller by transmitting Acknowledge Tones.
b) Informs you that a caller is on the Channel by emitting a CALL ALARM (Default Alarm Setting: four successive beeps in a regular interval for 10 seconds. Refer to p.40, 'Alarm Mode' for other alarm settings) and displays the CAL icon.
c) Flashes the TSQ icon for about 20 seconds allowing you to use the PTT button. If you are not able to respond within the 20 second period, TSQ icon stops flashing and 'QUIET' mode resumes.

The UH8055S can decode a Selcall call even though not in 'QUIET' mode.
Scanning Tone Squelched Channels
If you are using two or more Channels in the TSQ mode, you can monitor all of these Channels for selective calls by using the TSQ scanning feature.
To use this feature start the TSQ Scan by pressing and holding [TSQ] for 2 seconds during Open Scan or Group Scan.
Unlike Normal Scanning, TSQ scans and checks detected signals for Selcall information. If this information is not found, TSQ Scanning resumes.
When a call is received during TSQ Scanning, UH8055S follows the same response as when receiving a call on a Tone Squelch Channel. It differs only in the following ways:
- If the call is not answered within 20 seconds, TSQ Scanning resumes.
The CAL icon remains on the LCD display.
To look for the Channel where the CALL is received.
a) Cancel TSQ Scanning by pressing [SCAN].
b) Turn the Rotary Channel Selector to browse through the TSQ Channels. The CAL indicator marks the Channel where the Call is received.
- When answered, TSQ Scanning is automatically deactivated. The Channel is removed from the QUIET Operating Mode.
To deactivate TSQ Scanning:
a) Press and hold [TSQ] for 2 seconds.
The unit returns to Normal Scanning Mode.
b) Press [SCAN].
The whole scanning operation is cleared.
c) When a Selcall is received, press PTT.

NOTE
The chance of receiving and decoding Selcalls effectively during TSQ Scanning can be increased in many different ways. You can either decrease the number of channels to be scanned thus increasing the scanning speed – or – change some of the Selcall parameters (refer to 'Selcall Programming').
Group Calling
The UH8055S has the capability to respond to Group Calling and to transmit Group Calling Codes.
Group Calling allows you to call members of your group simultaneously. However, to do this, you need to follow a certain format (see below) when programming your TX Selcall ID.
Selcall ID Format
To call Transmitter SELCALL ID
10 radios [X] [X] [X] [X] [A]
100 radios [X] [X] [X] [A] [A]
1000 radios [X] [X] [A] [A] [A]
where: [X] is a common Selcall ID prefix of your group
- and - [A] is the CCIR Assigned Group Tone Code
Example:
If one group comprises 10 members with Selcall IDs the ID numbers could be as follows:
Group ID # Individual ID#
[1] [2] [3] [4] [0]
[1] [2] [3] [4] [1]
[1] [2] [3] [4] [2]
[1] [2] [3] [4] [3]
to -
[1] [2] [3] [4] [9]
all in TSQ mode at CH20
If someone transmits ID 1234A on CH20, all of the above units will open their Tone Squelched Receiver.
Group Calls and ordinary Selcalls can be differentiated in the following manner:
Group Call - Low tone beeps
Ordinary Selcall - High tone beeps
SELCALL Settings
Tone Period
Tone period is the duration of one tone in a Selcall ID sequence. The setting of this parameter depends on the type of application. On long distance communications, for example: where the signal strength of the transmitted information is greatly reduced and affected by noise, it is advisable to use a longer Tone Period. A long Tone Period gives the decoder more time and information to check and evaluate the code.

However, be sure that all the radios in your group use the same Tone Period setting. Otherwise you will not be able to selectively call one another.
The UH8055S allows you to select which Tone Period is best for you. The three most commonly used tone settings (40,70 or 100 mSec) are available. With the freedom to change this parameter, you can easily adapt to the existing system in your group without the inconvenience of having the unit serviced by the dealer.
- Power Off the UH8055S.
- Press and hold [POWER] and [MENU]. The SELCALL Settings Menu will display (no tone will sound).
- Press [MENU] repeatedly to select the Tone Period setting - which is indicated on the display as Pd.
- Press [SCAN] to edit the setting. The current setting flashes.
- Turn the Rotary Channel Selector to select the desired tone period from 40ms, 70ms or 100ms.
- Press [SCAN] to exit the setting.
- Press and hold [ENTER], to save and exit programming mode.
Lead-in Delay
Lead-in delay is a Selcall transmission parameter that ‘wakes-up’ and helps the receiver of the other radio to lock onto the incoming signal. Each time a Selcall ID is transmitted, the Lead-in Delay attaches itself to the beginning of the code sequence and causes the transmitter to be on for a longer period prior to the code transmission. This makes for a stronger communication link between the transmitter and the other receiver.
One major advantage to having the longer Lead-in Delay is when selectively calling another radio via a repeater station. A longer Lead-in Delay helps to stabilise both the communication link from your radio to the repeater station and from the repeater station to the other radio.
Lead-in Delay Programming
- Power Off the UH8055S.
- Press and hold [POWER] and [MENU]. The SELCALL Settings Menu will display (no tone will sound).
- Press [MENU] repeatedly to select the Lead-in Delay setting - which is indicated on the display as Ld.
- Press [SCAN] to edit the setting. The current setting flashes.
- Turn the Rotary Channel Selector to select the desired Lead-in delay period from 500ms, 1000ms, 2000ms, 3000ms or 4000ms.
- Press [SCAN] to exit the setting.
- Press and hold [ENTER], to save and exit programming mode.
Lead-in Tone
The Lead-in Tone, when programmed, 'rides' on the Lead-in Delay.
Hence, when transmitting a Selcall ID, a continuous tone will be heard for the duration of the Lead-in Delay. The main purpose of the Lead-in Tone is to increase the probability of contact between your unit and another radio when TSQ Scanning.
- Power Off the UH8055S.
- Press and hold [POWER] and [MENU]. The SELCALL Settings Menu will display (no tone will sound).
- Press [MENU] repeatedly to select the Lead-in Tone setting - which is indicated on the display as LT.
- Press [SCAN] to edit the setting. The current setting flashes.
- Turn the Rotary Channel Selector to select the desired Lead-in Tone.

- If you want to remove the Lead-in Tone choose the space [ _ ] Bar.
- Press [SCAN] to exit the setting.
- Press and hold [ENTER], to save and exit programming mode.
Alarm Mode
When a received code matches to your receiver Selcall ID the UH8055S will respond based on the Call Alarm mode.
Call Alarm - Auto mode (Default)
a) Transmit an Acknowledge tone to the Caller.
b) Emit CALL Alarm for 10 seconds only.
c) Resume Quiet condition automatically after 20 seconds if the call is not answered.
d) The Unit will start decoding again when the 20 second period elapsed and the call remained unanswered.
Call Alarm - Continue mode
a) Transmit an Acknowledge Tone to the Caller.
b) Initially an alarm of four successive beeps is emitted for 20 seconds and then two successive beeps every four seconds continuously unless answered.
c) The Quiet Condition is never resumed.
d) The Unit continues to check if incoming codes have your Receiver Selcall ID even though the Quiet Condition is already opened. When detected, it will send an acknowledge Tone to the caller and then resets the Call Alarm.

Always listen on a channel (or observe the receive signal level meter) to ensure it is not already being used before transmitting.
Channels 5 and 35 are used for emergency channels.
CTCSS, DCS, TSQ and SELCALL will not operate on these channels.
Please follow these guidelines for channel use in Australia:
- Channels 05 and 35 are Emergency Channels.
• Channel 11 is a Calling Channel. - Channels 22 and 23 are for telemetry and telecommand applications, channels 61, 62 and 63 are for future use and TX is inhibited on these channels.
General communication is accepted on all other channels with these guidelines:
- Channel 40 - road channel (Australia).
- Channels 01-08 (and 31-38), and Channels 41-48 (and 71-78) are repeater channels.

Important information - 80 Channel UHF-CB channel expansion
To provide all users additional channel capacity within the UHF-CB Band. The ACMA will change the majority of the current wideband 40 channel use to narrowband channel use. This allows for additional channels to be added, up to 80 Channels.
This simply means that the new narrowband radio you have purchased will have more channels than older radios. Please refer to the guidelines above and the channel chart for further channel information.
A list of currently authorised channels can also be obtained from the ACMA website in Australia and the MBIE website in New Zealand.
Interference / Poor Audio
When a new narrowband radio receives a signal from an older wideband radio the speech may sound loud - however the radio's built-in AVS (Automatic Volume Stabilizer) circuitry will detect and manage incoming audio to comparable levels.
Narrowband radios operating on CH41 - CH80 may encounter interference from a nearby wideband radios transmitting on high power on an adjacent channel (frequency).
When an older wideband radio receives a signal from a new narrowband radio the speech may sound quiet - the wideband radio user simply adjusts their radio volume for best performance.
The above situations are not a fault of the radio but a symptom of mixed wideband and narrowband radios in current use. It is expected that as older wideband radios are phased out this issue will be eliminated.
