11.0 Battery Warning
To obtain a defined status for the PinCode Keypad and to minimise operating errors,
a 2-level battery warning system has been integrated.
When the battery capacity begins to drop, you will be notified of this in plenty of time
to allow you to replace the batteries.
Battery warning level 1:
The opening procedure is carried out after a delay. The
diode blinks YELLOW and the buzzer sounds for 10 seconds.
The PinCode Keypad
does not send the open command until after these 10 seconds.
Battery warning level 2:
In this case, the opening procedure is again carried out
after a delay. The diode blinks YELLOW and the buzzer now sounds for 20 seconds
.
The PinCode Keypad does not send the open command until after these 20 seconds.
You should not wait any longer to replace the battery. Otherwise, the system will stop
functioning after a short time.
12.0 Battery Replacement
In general, the batteries must be replaced by trained experts only. To do this, proceed
as follows:
1. Completely unscrew the two screws in the bottom of the housing.
2. Remove the front of the housing.
3. Carefully release the battery clip from the printed circuit board (Figure 1).
4. Remove both batteries (Figure 1).
5. Insert the new batteries; the positive pole must be pointing up (Figure 2).
6. Carefully hook the battery clip back into the printed circuit board (Figure 3).
7. Put the housing back on.
8. Screw the two housing screws back into the housing from below.
After you have replaced the batteries, all functions will be available again.
Please always replace both batteries at the same time, because they have been
charged to approximately the same level.
