ALAN 121 Handheld Multi-standard CB transceiver
ALAN 121 is a small and easy to use CB transceiver. It’s extremely compact, sturdy
and benets 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
3. 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.
4. “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).
5. “Squelch” Control: For the maximum receiver sensitivity, the control must be regulated
exactly where the receiver background noise disappears.
6. “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.
7. Microphone jack: Insert the mic connector into this jack.

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 xing 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 conterclockwise.
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.
FREQUENCY BAND SELECTION
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).
