Battery check - Changing the battery
The smoke detector is supplied with voltage by a 9 V monobloc bat-
tery. The battery test automatically checks the supply voltage in regu-
lar intervals. If the battery voltage drops below a defined point, the
smoke detector signals for 30 days that the battery has to be replaced.
The smoke detector is completely functional during this period.
Proceed as follows to replace the battery:
1. Remove the smoke detector from the base (turn counter-clock-
wise).
2. Remove the old battery from the compartment and disconnect the
connector from the battery connection.
3. Connect the new 9 V monobloc battery to the battery connection
and insert the battery into the battery compartment.
4. Insert the smoke detector back into the base and latch it in by tur-
ning it slightly clockwise.
