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.

12 Main Features
INTERCOM FUNCTION
Thanks to the INTERCOM-function, this transceiver is especially
suitable for the use on motorbikes. The DUPLEX function
allows simultaneously communications between driver and
partner, as a phone conversation.
Connect the first headset to the Speaker/Microphone-jack at
the top of the transceiver and an optional accessory (throat
activated microphones, etc.) to the INT-jack of ALAN 456. To
use this function, set the PTT/VOX switch in PTT position.
ALAN 456 is now functioning as an Intercom system. To get
in contact with other motorbike drivers (using the same
frequency), the transmit mode can be done manually (PTT-
switch) or by voice controlled system (VOX). In this case, the
“PTT-/VOX” switch must be in “VOX” position. It is also
necessary the use of an appropriate accessory.
SCAN function
The Scan function is used to check the traffic radio on the 8
channels before transmitting.
There are 2 kinds: SCAN and B. SCAN
English

CTCSS: Continuous Tone Coded Signalling System
ALAN 456 can receive in two modalities:
a) open traffic: in this case you will hear any communication
transmitted on the selected channel.
b) group modality CTCSS/DCS: CTCSS and DCS tones
are “access keys” that allow you to receive only messages
coming from parties using same channel and code.
Speaker will remain muted until the correct CTCSS or
DCS tone is received (further details will be explained in
the successive paragraphes).
To activate 38 different CTCSS tones in RX and TX follow
these steps:
1. Turn on the radio.
2. Press button until “CTCSS” blinks on the display.
3. Select the desired tone (01/38) by the /keys.
4. Press to confirm the operations.
Now the radio transmits and receives using the programmed
CTCSS tone.
If you don’t want CTCSS tones, select “00”.
