2.1 Symbols used
For ease and convenience of use, this manual uses symbols to highlight urgent situations, practical advice, and general information.
! Exclamation marks such as this one indicate a crucial description regarding technical repairs, dangerous conditions, safety warnings, advice, and/or other important information. Ignoring these symbols may result in serious problems and/or damage and/or personal injury.
Notes such as this one indicate practical advice that we suggest be followed for the optimal performance of the equipment
2.2 Warnings
! DO NOT TRANSMIT WITH THE DAMAGED ANTENNA OR WITHOUT THE ANTENNA CONNECTED - although the radio is protected, this may seriously damage its R.F. power stages. Do not use your transceiver if the antenna is damaged.
! Do not keep the antenna too close to your head and body during transmission.
! Do not hold the transceiver by the antenna! This is a delicate part of the device and is vital for the proper functioning of the radio.
! Pay attention to environmental conditions - although the radio was designed to operate under the most severe conditions it is important to avoid exposure to environments that are excessively humid or dusty, or to temperatures outside the -15^ to +50^^ range. Also avoid exposure to direct sunlight.
! Avoid strong mechanical shocks and excessive vibration, the radio is designed to bear mechanical shocks and vibrations, provided that they're the normal ones borne by any electrical equipment.
! Do not use the radio, its accessories, and/or substitute the batteries in potentially explosive environments. A single spark may cause an explosion.
! BATTERIES - Strictly follow all the directions and warnings on the batteries stated at chapters 4.3 and 4.4
! Do not open the radio for any reason! The radio's precision mechanics and electronics require experience and specialized equipment; for the same reason, the radio should under no circumstances be realigned as it has already been calibrated for maximum performance. Unauthorized opening of the transceiver will void the warranty.
! Do not use detergents, alcohol, solvents, or abrasives to clean the equipment. Just use a soft, clean cloth. If the radio is very dirty, slightly dampen the cloth with a mixture of water and a neutral soap.
! Your VHF marine handheld transceiver has a built-in VHF radio transmitter. Be aware that, when you press the PTT button, the radio emits radio frequency (R.F.) energy.
! Before using the radio, ensure that all protective covers and parts are in perfect operating condition, in order to ensure maximum protection against humidity and atmospheric agents.

4. Preparing the transceiver
Make sure the following items are supplied in the package before you start using your transceiver:
- transceiver;
- desk/wall support;
- belt clip holder;
• waterproof case with neck collar
• operational manual;
If any of the above is missing or damaged contact your supplier immediately.
4.1 Installing and removing the belt clip
With the belt clip you can easily attach the transceiver to your belt. The clip however, must be removed in order to install or change the batteries. To remove the belt clip follow the instructions of picture 1. To fix the clip back to the device slot it in the guides at the back of the transceiver until it clicks into place.
4.2 Installing and removing batteries
The transceiver is operated by four optional AA battery. These can be either one of two types:
- Rechargeable NiMH (1,2 V) - available in different capacity (in mA/h). Batteries with higher capacity will supply longer charger but will require longer times to recharge.
• Non-rechargeable alkaline (1,5 V)
! Do not install rechargeable and alkaline batteries at the same time in your transceiver. Always use the same batteries as a set (type and make) so that you can be sure their level of charge is the same.
! If you do not use the transceiver for a long time remove the batteries.
4.2.a Installation
1) Remove the belt clip as explained in paragraph 4.1;
2) Open the batteries compartment as shown in picture 2;
3) Insert the batteries in the battery compartment as shown in picture 2.

4.2.b Removal
1) follow steps 1 and 2 of par 4.2.a;
2) Remove the batteries from the device;
3) Follow steps 4 and 5 of par 4.2.a.
4.3 Recharging batteries
Batteries can be recharged without taking them out of the transceiver (but the device must be turned off); Batteries take 12 -13 hours to fully recharge (rechargeable batteries1700mA/h).
To recharge batteries:
- Carefully lift the rubber protection of the socket MIC/CHG
- Insert the jack of the battery charger (sold separately) in the socket MIC/CHG of the radio, then connect the battery charger to a mains power socket. Charging will begin
- When charging is complete pull out the charger's jack from the radio and detach it from the mains. Replace the rubber protection mentioned in step 1.
! Do not overcharge the batteries! When these are fully charged the charging process does not stop automatically. Do not forget therefore, to remove the charger from the transceiver as soon as the batteries are charged.
! Do not try to charge alkaline batteries or non rechargeable batteries. Make sure that when you connect the charger only rechargeable batteries NI-MH should be contained in the batteries compartment! It is very dangerous attempting to recharge other types of batteries (for example alkaline or manganese batteries). Batteries which are not suitable to be recharged may leak, explode or even burn and cause damage!
! Using a different battery charger other than the one specified can cause damage to your device or may even cause explosions and personal injuries.
! Do not throw batteries into fire or place them near heat as this may cause explosions or personal injuries. Dispose of the batteries according to procedures set out by local regulations.
! Do not mix old and new batteries or batteries of different types or batteries which have been used in different manners. Every battery set which is being used must always be composed of the same elements.
4.4 Memory effect of rechargeable batteries
Rechargeable NiMH (Nickel-Metal-Hydrate) batteries are affected by what is known as the "memory effect". This phenomenon is associated with a drastic reduction of battery autonomy and is triggered if the batteries are regularly charged before being fully discharged and/or are not completely recharged. To avoid the memory effect:
- When possible, recharge the batteries only when they are completely discharged (until the device turns itself off during normal use)
- Do not disconnect the battery charger before the time indicated for a full battery charge.
- Discharge and recharge your batteries completely at least twice a month. In any case, the best solution for avoiding the memory effect is to use in turn two battery sets: one in use, and the other as a spare set.
The memory effect can be easily eliminated by completely discharging/charging the batteries 3 or 4 times.
The memory effect should not be confused with the normal battery life, which is 400 cycles of charge/discharge on average. It is completely normal for operating duty to decrease when the batteries have reached the end of their life; at this point, you will need to substitute the battery set.
5. Basic operations
5.1 Turning on/off
To turn on the transceiver, turn the ON/OFF/VOLUME knob clockwise until you hear it clicks: the LCD display will light up and do an Auto-Test. Subsequently you will hear 3 beeps of different tones. To turn off the transceiver, turn the knob counter-clockwise until you hear another click. The LCD display will turn off and subsequently you will hear 3 beeps of different tones.
5.2 Selection of the operational channel
1) Press once the MENU[17] button. The number of the channel will start flashing on the display.
2) Press the scroll buttons ▲/▼19] to scroll up or down the channel list till you select the desired channel.
3) Press the PTT[11] button to confirm, or wait for 5 seconds.
Refer to the table of frequencies of Chapter. 10. Moreover, the reception frequency could be different (duplex channels) from the transmission frequency or it could be the same (simplex channels). Normally communications among vessels can only take place on simplex channels.
5.3 Volume control
Turn the knob VOLUME[10] to about half way and adjust it to a comfortable level as soon as you receive a signal. If you do not receive a signal you can use the button MON/SCAN[18] described at par. 5.5.
Ensure the channel you've selected is not a reception-only channel (if it is, the transmission will be disabled) and that no one else is talking (this will appear on your display as the BUSY icon).
5.4 Transmission and reception
The button PTT[11] is located on the top left side of the device. To transmit:
1) Make sure that the selected channel is not reception-only (if it is transmission will be disabled) and that no one else is currently talking;
2) Keep button PTT[11] firmly pressed: TX[2] will appear on the display;
3) Before you start talking wait for a fraction of a second then speak normally, in the direction of the microphone, and hold the device at a distance of about 5 cm.
4) When you have finished release the button PTT[11]: TX[2] will disappear from the display;
5) When the button is in reception mode (PTT[11] not pressed) you will automatically receive any communication;
During transmission and reception try, as far as possible, to keep the antenna in vertical position and to avoid obstacles towards the direction of the other party.
5.5 Button MON (Monitor)
The Monitor button is for temporarily excluding (opening) the squelch, in order to listen to signals that are too weak to keep the squelch permanently opened. By excluding the squelch you will avoid listening the communication “chopped” by the squelch. In order to activate the Monitor function, so as to listen to all traffic on the selected channel, keep pressed the MON/SCAN[18] button for about 2 seconds. Keep pressed the button MON/SCAN[18] for about 2 seconds to disable this function.
5.6 Choosing high or low transmission power
Batteries are drained more quickly during transmission. In order to extend the battery life you can select the low power when transmitting over short distances:
1) Press the MENU[17] button twice and the writing Pr will display.
2) Select LO[8] using the scroll buttons ▲[19].
3) Press PTT[11] to confirm, or wait for 5 seconds.
If you want to transmit a longer distance repeat the above procedure to select the high power. At step 2 use the scroll buttons ▲/▼[19] to make the writing LO[8] disappear. When the batteries are in good conditions, high power is about 5 watt, whereas low power is about 1 watt.
A low battery level during transmission will have a negative effect on the performance of your device.
5.7 LCD backlight
If there is insufficient light to read the display you can press the MENU[17] button to switch the display back light on for about 5 seconds.
Switching the back light on the display adds an additional drain on the batteries. Try to make a moderate use of this.
5.8 Instant selection of Channel 16
Channel 16 is the marine channel most frequently used for emergency. Your transceiver is equipped with a button that provides instant access to this channel. To recall rapidly channel 16 press the button CH 16[12]. No matter what mode the device is operating, channel 16 will be selected immediately. To go back to the previously selected channel press again the button CH 16[12].
5.9 Power saving feature
The battery power saving feature enables a reduction in the consumption of up to 50%; Power saving comes on automatically when the transceiver does not receive any signal for more than seven seconds. When the battery pack is discharged (the icon ☐[3] appears on the display) batteries need to be substituted or recharged if they are Ni-MH type.
6. Advanced functions
6.1 Scanning all channels
Atlantic XT can automatically search for signals throughout the marine band by scanning, i.e. selecting the channels in rapid sequence. When a signal is detected, the scanning pauses on that channel and remains blocked for five seconds before automatically begins scanning again to give you the chance to find other communication.
Press briefly the button MON/SCAN[18] to start scanning:
Press again MON/SCAN[18] to stop scanning. Your transceiver will go back to the channel from which the scanning originally started.
Once you are tuned in the communication you were looking for, press PTT[11] to talk on the selected channel. Atlantic XT will however remain in scanning mode (which is indicated by the flashing of the channel on the display) and it is possible to start scanning again by pressing on the scroll buttons ▲/▼[19]. If you press PTT[11] during scanning you can transmit on the channel from which the scanning started. The scroll buttons ▲/▼[19] allow you to change the direction of scanning (from lower channels to higher ones or vice versa) and therefore to skip communications which are of no interest.
6.2 VOX Function
Atlantic XT enables hands free conversations through VOX function. The degree of sensitivity of VOX function can be adjusted to three different levels. You can enable VOX function with or without accessories.
1) To activate VOX function press the MENU[17] button three times and VOX[1] will appear on the display
2) Use the scroll ▲/▼19] buttons to select:

The CALL function warns other users tuned in on the same channel of the arrival of a call. To send the signal to another user press twice button PTT[11]. On the display TX[2] will appear and the Speaker [14] will give out a sequence of sounds which you have previously chosen.
Atlantic XT gives you the chance to select different tones to send. Tone 1 is factory set.
To select the sequence of tones:
1) Press six times the MENU[17] button; the writing CA will appear on the display
2) Using the scroll buttons ▲/▼[19] select 1, 2 o 3. During selection you will be able to hear the relative tone.
3) Press PTT[11] button to confirm, or wait for 5 seconds.
7. Troubleshooting
Your Atlantic XT is designed to provide you with years of optimal performance. If for some reason problems arise, refer to this chapter before contacting a service centre in your region.
7.1 Reset
If your transceiver experiences a logical malfunction (improper symbols on the display, blocking of functions, etc.), it may not be experiencing a true failure, but rather a problem caused by external factors. For example, it may have an incorrect setting brought on by a noise or spikes in the electrical system during battery recharging. In such cases, you can reset the transceiver to its factory-programmed settings, by resetting all parameters:
1) Turn off the transceiver
2) Remove the batteries for about 60 seconds (Par.4.2)
Before you go ahead with the reset, we recommend that you take note of all the setting you have carried out as they will be deleted.
