1-6 Power supply and battery charging

The AR8200 is designed for operation from internal batteries or from its supplied a.c.-to-d.c. charger.
Operation is possible from another good quality regulated d.c. supply of 12 to 14V, which should be
capable of supplying 300mA. Never connect the AR8200 directly to the a.c. supply.
The d.c. input socket uses a mini 1.3mm power connector. This connector is configured CENTRE
POSITIVE, the chassis of the receiver is at negative ground. The charger supplied is pre-wired and
provides a nominal 12V d.c. output with suitable connectors being fitted as standard for the a.c. power
input and connection to the AR8200.
SAFETY NOTICE - Always disconnect the charger from the a.c. socket when not in use.
If you are not going to use the AR8200 on batteries for a while, remove the batteries from the radio
(to prevent dry cells leaking) and charge NiCads before placing them into storage.

1-6-1 Internal batteries
