INTRODUCTION
ALAN 42 MULTI is a small-size portable transceiver which guarantees
the best performance during the years even under heavy conditions.
What is unique to this innovative transceiver is the capability to select
any of the European CB bands with an easy and fast procedure.
ALAN 42 MULTI has a built-in Channel Phase Loop synthesizer (PLL)
circuit and an automatic battery economy circuit.
The wide display can be illuminated and allows the night use. Optional
microphones can be connected to the equipment thanks to the external
mike plug situated on the upper side of the radio.
The unit is preset at the factory on the “EC“band , CEPT 40CH FM
4W.

1. Antenna connector: insert into this plug the antenna supplied with the radio. It is
possible to use external vehicular antennas to obtain a better performance.
2. Squelch Control: this control cancels the background noise of the receiver. By
turning the knob to the right the function is activated, by turning the knob to the
left the function is deactivated. The knob should be regulated exactly at the point
where the receiver background noise disappears.
3. 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.
4. MIC jack: connect by inserting the loudspeaker mike to the plug.
5. External loudspeaker jack: connect by inserting the loudspeaker mike to the
plug.

This liquid crystal display has been projected to show the operative modality:
a. EMG function activated
b. Channel selected number( from 1 up to 40)
c. Lock: keyboard lock function activated
d. BATT: Run-down batteries indicator
e. AM/FM mode
f. SC: SCAN function activated
g. DW: DUAL WATCH function
h. P. S.: Save function activated
i. LOW function activated
j. The received signal strength and the power of the transmitting signal
k. RX/TX: TX=transmit mode; RX=receive mode
l. Frequency band selected
8. EMG button: emergency channel. By pressing this button, the unit automatically
skips to Channel 9 (emergency channel). The display will shows EMG. It will not
be possibile to change accidentally the channel. To cancel this function, press the
button again.
9. A/F–LCR button: to select AM mode or FM mode; the modulation you choose will
appear on the display. If you select a frequency band operating in FM mode only,
the A/F–LCR button will activate the LCR function (Last Channel Recall).
10. Microphone: during transmission, keep your mouth 4 cm far from the unit, and
speak with a normal tone of voice to the microphone.
11. H/L button: it selects the output power level during trasmission.When the unit is
turned on, it always transmits with high power (4W). By pressing this button, the
unit will transmit with low power (1W). The display will show “LOW”. Press again
the H/L button to return to “HIGH” power level.
12. LOCK button: it allows you to lock the keyboard, thus avoiding accidental use of
the keys.
13. Q.UP - Q.DOWN buttons: to skip 10 channels up (Q.UP) or 10 channels down
(Q.DOWN).
14. Loudspeaker
15. Dual Watch: this function allows the synthonization on two different channels at
the same time. Thanks to this function, you can monitor a second channel. When
a signal on the second channel is received, the conversation on the first channel
is automatically interrupted and the receiver switches on the second channel. The
monitoring starts again 4 seconds after the signal end.

To activate this function, operate as follows:
- Select the desired channel through the channel selector
- Press the DW button
- Select the second channel
- Press the button DW again
- To cancel the function press again the DW button or the PTT button.
16. SCAN button: with this control, you can automatically seek for a busy channel.
• Turn the Squelch clockwise until the background noise is no longer heard.
• Press the ''SCAN'' button: the transceiver will scan automatically all the
channels until a carrier is being received.
• When it finds the carrier, it stops and starts again some seconds after the end
of the communication on the channel.
• When the radio is transmitting, the scan function is deactivated.
17. ✩ button: display lighting (temporized).This function allows to operate in darkness
conditions. By pressing this button, the display is lighted for 5 seconds.
18. Push to talk button (PTT): Its pressure activates the transmission. When it is
released, the receiver is activated.
19. Battery compartment: insert 6 Ni-Cd alkaline batteries.

21. Channel UP: to skip to the next channel. Keeping this button pressed, the
“autorepeat” function is obtained.
22. Channel DOWN: to skip to the previous channel. Keeping this button pressed, the
“autorepeat” function is obtained.
23. Battery pack contact: lift the button and take the batteries out (see drawing).
24. Auxiliary antenna contact: for the connection to the vehicular adaptor.

1. Insert the antenna in the antenna connector.
2. Insert 6 alkaline batteries into the battery compartment, noting polarity (the alkaline
batteries are not rechargeable)
3. Rotate the ON/OFF volume control clockwise to turn the unit on. Adjust the volume
for a normal listening level.
4. Adjust the SQUELCH control
5. Select the desired channel by the UP/DOWN or QUICK UP/QUICK/DOWN
buttons
Note: if the channel does not change,control that the EMG or LOCK button has
not been pressed. In this case, press the EMG or LOCK button to deactivate
this function.
As far as the other functions are concerned, refer to previous instructions.
To transmit: press and hold the PTT button, then talk to the microphone.
To receive: simply release the PTT button.
CAUTION: DON’T EXPOSE THE DISPLAY TO EXTREME TEMPERATURES.
FREQUENCY BAND SELECTION
The frequency bands must be chosen according to the country you are in.
Procedure:
1. Switch off the unit.
2. Turn it on while pushing the “A/F-LCR” and “SC” buttons.
3. By pushing the ▲ e ▼ buttons, select the desired frequency band (see the chart
here below).
4. To fix your selection, press the “A/F-LCR” button.
NOTE: If you select a frequency band which operates in FM mode only, the “A/FLCR” control activates the LCR function (Last Channel Recall).
