Operation Manual
Care of optional rechargeable Ni-Cd/Ni-MH
batteries
Allow the batteries to fully discharge before recharging.
This operation will extend the battery life.
• Full discharge will be indicated by the
flashing on
the display.
• Always allow the battery to fully charge before using.
Do not perform partial cycles which reduce their capacity
in a long time.
In case Ni-MH batteries are used, it is greatly suggested
removing the unit from the optional charger at the end
of the recharge cycle.
• It is better to store Ni-Cd/Ni-MH batteries that are
discharged rather than charged.
Do not mix old and new batteries or rechargeable
batteries of different capacities.
Accessories
ALAN 451 is equipped with a 2 pin standard jack for external
speaker/microphone and recharge jack for Ni-Cd/Ni-MH
batteries.
To enjoy your radio for a long time
While ALAN 451 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
dust or extreme temperatures. Never place the unit into
the water.
Do not connect the unit to a power higher than the
working one.
To power the radio in your car use only “AL25” charger
(working with rechargeable batteries only).
Cleaning
Clean the unit with a damp cloth only; do not use harsh
chemicals.
