BATTERY WARNING
A two-level battery warning system has been integrated to achieve a defined status for
the pin code terminal and minimise operating errors. This system signals decreasing
battery capacity at an early stage, so that action can be taken to replace batteries in
good time.
Battery warning level 1:
The opening procedure is delayed slightly. The diode flashes yellow and the buzzer
sounds for 5 seconds. The pin code terminal delays sending the open command for
5 seconds.
Battery warning level 2:
The opening procedure is delayed. The diode flashes yellow and the buzzer sounds
for 10 seconds. The pin code terminal delays sending the open command for 10 sec-
onds. Batteries must be replaced at this stage at the latest. If not, the system will no
longer be able to function after a short period of time.
CAUTION: it is not possible to access programming mode when the battery warning
is active. This means no functions can be changed or deleted while the battery is low.
Programming mode will only become available once the batteries have been suc-
cessfully replaced (see section on Battery replacement).
10.0 BATTERY REPLACEMENT
As a general rule, only trained personnel may replace batteries. Proceed as follows to
do so:
1.
Remove the two screws (Torx TX6) from the casing base.
2.
Detach the front of the casing.
3.
Carefully unfasten the battery holder on the circuit board (Fig. 2).
4.
Remove both batteries (Fig. 1).
5.
Insert the new batteries; the positive pole must point upwards (Fig. 2). Only use
clean gloves free of fat or grease to handle the new batteries.
