Operation Manual

Introduction
The PMR446 Communication Service
Congratulations for your choice! ALAN 451 is a new generation
transceiver, PMR 446 type, that can be used without license
in all the countries in which Pan-European PMR446 frequencies
are authorised.
Coverage
The operating band (446 MHz) allows clear communication,
virtually free from atmosperich interferences up to a
distance of 5 km.
The maximum range is obtained operating in a open space.
The only limit to maximum possible range are environmental
factors such as blockage caused by trees, buildings, or other
obstructions. Inside a car or a metallic constructions, the
range can be reduced.
Table of symbols
To become more familiar with your ALAN 451 and to make
your reading quicker, we have added a series of symbols that
are described herebelow:
Short cuts for use: they concern hints and
tips for a quicker use of the radio.
Cautions: they are special notices you
should carefully read and follow to avoid an
improper use of the transceiver and its
accessories. They concern international
security regulations, too.
New/unique: they emphasize peculiar
features of ALAN 451.
Batteries
ALAN 451 uses 3 AA type alkaline batteries (dry cells), or Ni-
Cd/Ni-MH batteries (rechargeables).
Notes:
• For a proper working of the unit, batteries must be in good
condition and fully charged.
• Remove batteries before storing your radio for extended
periods. Batteries corrode over time and may cause
permanent damage to the unit. This operation, besides,
preserves battery life.
• Never use different batteries from the ones suggested.
