Your ALAN 78 PLUS MULTI represents the state-of-the art in high-tech engineering.
Designed for the Citizen Band Mobile operation, this compact package is big in
performance. It is a quality piece of electronic equipment, skillfully constructed with
the finest components. The circuitry is all a solid-state, mounted on rugged printed
circuit boards. It is designed for many years of reliable, trouble-free performance.
Your mobile CB has a built Phase-Locked Loop synthesizer circuit.
The PLL circuit achieves a new technique for generating all the required frequen-
cies with fewer crystals. The result is much tighter frequency control and superior
reliability.
Important Note
Following national regulations have been modified:
Residents of Belgium, Great Britain, Spain and Switzerland need a CB licence in
their countries, while visitors may use their CB radios in FM free of licence, for AM
they should be able to present their home-country’s licence document. In Italy, even
visitors need a valid Italian authorization.
Austria does not accept any multi-standard or programmable CB radio. Please
respect this requirement and do not use Your radio during driving through Austria.
In Germany transmitting as a base station on channels 41-80 is restricted in some
areas along the country borders. No restrictions apply for mobile use. More details
can be obtained from the local RegTP authority office.
Changes in European or national regulations will be published on the service website
of ALAN-Albrecht under www.alan-albrecht.info

FUNCTION AND LOCATION OF THE CONTROLS
1. Channel selector
2. Multifunction backlighted display. It shows:
A. Channel selected number
B. The received signal strength and the power of the transmitting signal
C. AM/FM mode
D. RX/TX:TX=transmit mode; RX=receive mode
E. SCAN mode
F. EMG mode
G. Frequency band selected.
H. LOW: displayed when the radio transmits in low power (this mode is pos-
sible with some frequency bands only – see the Frequency band chart).
I. LOCK: microphone (UP/DOWN buttons) lock enabled.
3. ”EMG” button: Emergency channel. By pressing it, you will be automatically
positioned on CH 9 (emergency channel). The display will show “EMG”. It will
not be possibile to change accidentally the channel.
4. 5. “Q.UP/Q.DOWN” buttons: To skip 10 channels UP (Q. UP) or 10 channels
DOWN (Q.DOWN).
6. “AM/FM”(LCR) button: To select AM or FM mode. If you switch on the unit
and push “AM/FM”(LCR) and “SCAN” at the same time, you will select the

INSTALLATION
Safety and convenience are the primary consideration for mounting any piece of
mobile equipment. All controls must 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, is very important
to observe the polarity even if the unit is protected against the accidental inversion:
5HG SRVLWLYHSROH
Black = negative pole (-)
The same colors are present on the battery and in the fuse box of the car. Correctly
connect the cable terminal to the battery.
ATTENTION
To obtain best performances we recommend to install the radio in a place with
enough air circulation.
INSTALLING AN ANTENNA
1.Place the antenna as high as possible
2.The longer the antenna, the better will be the performance
3.If possible, mount the antenna in the center 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 “AM/FM” e “SCAN” buttons at the same time.
Rotate the “CHANNEL” knob and select the desired frequency band (see the chart
here below).
To stop your selection, press the “AM/FM” button.
NOTE1: In the UK frequency band, you can select directly the EC band by pushing
the “AM/FM” button for 2 seconds.
NOTE2: If you select a frequency band which operates in FM mode only, the “AM/
FM” control enables the LCR function (last channel recall).
