Replacing the battery of the
locking cylinder
When the Low Battery alarm sounds, the battery of the locking
cylinder must be replaced. The Low Battery alarm starts
sounding when the battery capacity is falling. In this case, you
will hear a very long beep with every locking attempt.
The battery is inserted in the electronics module in the inside
knob. To replace the battery, the locking cylinder must be
pulled out slightly so that you can apply the flat key to release
the cover. Proceed as follows:
NOTICE
The door cannot be opened again once the
battery is completely empty.
Always replace the battery after the first Low
Battery alarm.
If the battery is completely empty, the door must
be opened with an Emergency Power Supply (see
page 60, Chapter "Emergency Opening").
When the battery is replaced, the programming
data remain stored in the memory of the locking
cylinder.
