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.

ENGLISH

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).
