Keypad illumination
Directly above the Keypad panel (C) is the slightly bevelled surface of the
proximity sensor (F). When your hand approaches the Keypad, the inte-
grated proximity sensor reacts, and the Keypad illumination is switched
on. This means you can always make out the keypad panel of your Key-
pad even in dim outdoor lighting.

Changing the batteries
If the battery symbol is displayed via the app or an empty battery is in-
dicated on the device (see „7.5 Error codes and flashing sequences" on
page 33), replace the two used batteries with two new LR03/Micro/
AAA batteries. Take care to observe the correct battery polarity.
To replace the Keypad batteries, please proceed as follows:
Remove the Keypad (B) from the wall bracket (A), by inserting a
•
thin object into the hole on the bottom of the wall bracket and
releasing the latch (M) (see figure 3).
You will now receive a tamper message in your app. This can only be
acknowledged when the Keypad has been reinserted in the wall
bracket after replacing the batteries.
•
Open the rear battery compartment (J) of the Keypad (B), by loos-
ening the screw of the battery compartment cover (see figure 4).
•
Remove the used batteries.
•
Insert two new 1.5 V LR03/micro/batteries into the battery com-
partment, making sure that you do so with the correct polarity
(see figure 5).
•
Close the battery compartment and tighten the screw on the bat-
tery compartment cover again.
•
Insert the Keypad back in the wall bracket (A).
You can now acknowledge the tamper message in your app.
