Frequently Asked Questions - ALAN 121 MIDLAND

How to change the frequency band on the ALAN 121?

To change the frequency band, turn off the radio, press and hold the UP and DOWN keys while turning the device back on. Then use the UP/DOWN keys to select the desired country code (see code table in the manual). Wait 5 seconds or turn the radio off and on again to confirm.

How to adjust the squelch on the MIDLAND ALAN 121?

The SQUELCH knob eliminates background noise. Turn it fully counterclockwise for maximum sensitivity, then slowly turn clockwise until the background noise disappears. Do not go beyond this point to avoid reducing reception of weak signals.

How to change the backlit display color?

Use a pointed object (like a paperclip) to press the button located in the small hole provided for this purpose. Each press changes the color among the following options: white, yellow, purple, red, light blue, green, blue or no color. The radio stays on during selection.

What does the LCR function (Last Channel Recall) mean?

The LCR (Last Channel Recall) function is active when the selected frequency band supports only FM mode. In this case, the AM/FM/LCR button no longer switches between AM and FM but recalls the last channel used. Press briefly to return to the previous channel.

What to do if the radio does not transmit or the signal is weak?

First check the antenna connection and ensure it is properly connected (SO239 connector) and well grounded. An antenna fault can damage the transmitter. Also check the SWR (Standing Wave Ratio) with a suitable meter. Make sure the radio is on and the volume is sufficient. If the problem persists, check the power supply (red wire positive, black negative).

How to install the CB antenna correctly?

Place the antenna as high as possible and, if possible, in the center of the mounting surface. The longer the antenna, the better the performance. Keep the cable away from sources of interference (ignition coil, gauge, etc.). Ensure good grounding and do not bend the cable during installation. Never use the radio without an antenna.

How to connect the power supply of the ALAN 121 in a vehicle?

The device operates on 13.8 V DC (direct current, like a car battery). Connect the red wire to the positive (+) terminal of the battery and the black wire to the negative (-) terminal. It is advisable to install a switch cutting both poles. Observe polarity even if the radio is protected against reversal.

What to do if the radio does not turn on?

First check the supply voltage (13.8 V DC) at the power cable using a multimeter. Ensure connections are correct and the fuse (if any) has not blown. Turn the ON/OFF knob clockwise to turn on. If nothing happens, check cable continuity and the plug.

How to select a specific channel?

Use the UP and DOWN keys on the front of the radio to browse channels. The display shows the selected channel. For quick access, you can use the LCR function (if available) to return to the last channel. The number of channels depends on the chosen frequency band (up to 40 FM).

What is the difference between AM and FM modes on the ALAN 121?

AM mode (Amplitude Modulation) and FM mode (Frequency Modulation) are two different modulation types. The ALAN 121 allows switching between them with the AM/FM button (unless the chosen band is FM-only). In FM, audio quality is generally better and less sensitive to interference, while AM offers potentially longer range under certain conditions. The selection depends on the frequency band and country regulations.

ALAN 121 Handheld Multi-standard CB transceiver

ALAN 121 is a small and easy to use CB transceiver. It's extremely compact, sturdy and benefits from basic controls that will satisfy even the most demanding of users. The backlit display can be customised with 7 different colours. Its main feature is its ability to operate in many European and extra-European countries simply by selecting the desired frequency band. The ALAN121 is supplied with a high-performance microphone which guarantees excellent modulation.

FUNCTION AND LOCATION OF THE CONTROLS

1. Channel selector
2. Multifunction backlighted display. It shows:

A. Frequency band selected.
B. Channel selected number
C. EMG mode
D. AM/FM mode
E. RX/TX:TX=transmit mode; RX=receive mode
F. LOW: displayed when the radio transmits in low power (this mode is possible with some frequency bands only – see the Frequency band chart)
G. The received signal strength and the power of the transmitting signal

1. Button for changing colour: by pushing a pointed object into the hole, you can change the backlight colour of the display. You can choose amongst the following colours: white, yellow, violet, red, light blue, green, blue or no colour.
2. "AM/FM"(LCR) button: To select AM or FM mode. If you select a frequency band operating in FM mode only, this button enables the LCR function (Last Channel Recall).
3. "Squelch" Control: For the maximum receiver sensitivity, the control must be regulated exactly where the receiver background noise disappears.
4. "ON/OFF Volume" Control. In "OFF" position your transceiver is OFF. Turn this control clockwise to switch on the unit. Turn the knob clockwise a little more to set the audio level, until you get a comfortable reception.
5. Microphone jack: Insert the mic connector into this jack.

1. "EXT" jack: external loudspeaker jack.(the internal loudspeaker is excluded)
2. Power 13.8V DC: power supply cable
3. S.Meter jack: it allows an external "S. Meter" connection
4. Antenna connector (SO239 connector type)

MICROPHONE

1. PTT: transmission button
2. UP/DOWN buttons: manual channel selector.
   3.6 pin microphone connector

INSTALLATION

Safety and convenience are the primary consideration for mounting any piece of mobile equipment. All controls must be readily available to the operator without interfering with the movements necessary for safe operation of the vehicle. Set the proper position in the car to install the transceiver using the supplied supporting bracket or eventually the slide bracket.

Tighten the retaining screws. The fixing bracket must be close to metallic parts.

POWER SUPPLY

Be sure the transceiver is OFF. In the direct-voltage power supply, it is very important to observe the polarity even if the unit is protected against the accidental inversion:

Red = positive pole (+)

Black = negative pole (-)

The same colours are present on the battery and in the fuse box of the car. Correctly connect the cable terminal to the battery.

INSTALLING AN ANTENNA

1. Place the antenna as high as possible
2. The longer the antenna is, the better will be the performance
3. If possible, mount the antenna in the centre of whatever surface you choose
4. Keep antenna cable away from noise sources, such as the ignition switch, gauges,etc.
5. Make sure you have a solid metal-to-metal ground connection.
6. Prevent cable damage during antenna installation.

WARNING: To avoid damage, never operate your CB radio without connecting a proper antenna. A periodical control of the cable and of the S.W.R. is recommended.

HOW TO OPERATE WITH YOUR TRANSCEIVER

1. Screw the microphone plug into the microphone jack.
2. Make sure your antenna is securely connected to the antenna connector.
3. Make sure the SQUELCH control is turned fully counterclockwise.
4. Turn on the unit and adjust the volume control.
5. Select your desired channel.
6. To transmit, press the PTT button and speak in a normal tone of voice.
7. To receive, release the PTT button.

The frequency bands must be chosen according to the country where you are going to operate.

Procedure:

Switch off the unit.

Turn it on while pushing the "UP" and "DOWN" buttons at the same time.

Select the desired frequency band by pushing the UP / DOWN buttons (see the chart in the following page).

Wait for 5 seconds or switch off and then on the radio.

NOTE1

In the UKE or UKC frequency bands, you can select directly the other band by pushing the "AM/FM/LCR" button for 3 seconds.

NOTE2

If you select a frequency band which operates in FM mode only, the "AM/FM/LCR" control enables the LCR function (last channel recall).
