2Introduction
INTRODUCTION
ALAN 456 is a new generation handheld transceiver PMR 446
type. It can be used without license in all countries where
PMR 446 frequencies are authorised.
Coverage
The operating band (446Mhz) allows clear communication,
virtually free from atmospheric interferences and -despite the
low power - will allow you to communicate up to a distance
of 5 km (under optimum conditions).
The only limit to maximum possible range are environmental
factors such as blockage caused by trees, buildings, hills, or
other obstructions. If you find communication is not possible,
many times this can be solved by moving a few meters to a
new location. Range is also reduced while operating in a
vehicle or metal building.
Batteries
The radio uses 3 AA type alkaline (dry) or 3 AA Ni-Cd
rechargeable batteries.
• Do not leave batteries installed over a long period of time
as leakage may occur and this can destroy the radio.
This operation, besides, preserves battery life.
• Never use different batteries from the ones suggested.
Attention: to obtain proper operation, batteries must be in
good condition and fully charged.
Care of optional rechargeable Ni-Cd batteries
The following is meant as general information regarding Ni-
Cd batteries.
• Allow the batteries to fully discharge before recharging.
Full discharge will be indicated by flashing on the
display.
• Always allow the battery to fully charge before using to
prevent the batteries from developing “memory”, which
effectively reduces their capacity.
• It is better to store Ni-Cd batteries that are discharged
rather than charged.
• Never use batteries which differ from the ones
recommended. Do not mix old and new batteries or
rechargeable batteries of different capacities.
English
Accessories
ALAN 456 is equipped with jack for external speaker
microphone, intercom system and charge jack for Ni-Cd
batteries.
To enjoy your radio for a long time
• While ALAN 456 has been designed for many years of
reliable, trouble-free performance, it is a precision piece
of electronic equipment that should not be exposed to
moisture, dust or extreme temperatures.
• Do not connect the unit to a power higher than the working
one.
• To power the radio by the car, do not use a cigarette
lighter adapter: use “AL25” charger only.
• Clean the unit with a damp cloth only; do not use harsh
chemicals.

How to use your ALAN 456 9
Select the desired VOX level by means of the /
buttons. The VOX sensitivity is now adjusted.
4) Press again the button: the display shows:
With these steps you can select the desired level, so that
the radio switches in RX in the desired delay. 01 level is
the shortest time, 06 level is the longest one.
5) To confirm the operations, press the key or turn off
the radio.
To transmit, speak into the microphone – the voice
automatic control switches ALAN 456 into transmit mode.
Note: In sites with very loud background noise, to set
the switch in position “06” ( select “LE vox 06”) is
recommended.
Voice-controlled transmit mode (VOX)
Your ALAN 456 is equipped with PTT (manual transmit mode)
and VOX (automatic voice control). The VOX can be adjusted
in 6 positions: from 01 (higher sensitivity) to 06 (lower
sensitivity). 01 position is recommended in quiet sites; 06
position is ideal for the operation with microphone/loudspeaker
or for room monitoring with large background noise.
