Battery/rechargeable battery recognition
After a battery/rechargeable battery has been inserted, the
battery recognition and receiver start-up procedure begins.
You will hear a beep when the procedure ends.
If a newly inserted battery is very weak, the receiver will not
recognize immediately whether a dry cell or rechargeable
battery has been inserted. The receiver will assume that a
rechargeable battery has been inserted and charging will
start automatically. The receiver will then measure the
battery voltage. When the threshold voltage has been
reached, the battery recognition and receiver start-up
procedure is activated. The battery is recognized and the
relevant information is stored in the receiver. If a recharge-
able battery has been inserted, charging will continue. If it is
a dry cell battery, charging will stop.
The recognition can take up to ten minutes. During this time
the battery will be charged.
Some types of receiver offer manual selection of "Recharge-
able/dry cell battery".
Please refer to the receiver manual for further information.

If there is a power failure, the relay contact will close if all calls
have not been acknowledged by the receiver. If a call is re-
ceived while in the charger and a power failure occurs,
contact is activated again as soon as power returns.
