Replacing batteries

If the symbol for empty batteries ( ) appears, replace the 

used batteries by two new LR03/micro/AAA batteries. You 

must observe the correct battery polarity.

To replace the batteries of the accessory, proceed as fol-

lows:

1.  Once mounted, the electronic unit 

(B)

 can easily be 

pulled out of the frame 

(A) 

and removed from the 

mounting plate 

(F)

. Grab the sides of the electronic 

unit and pull it out 

(see figure 6)

. You do not need 

to open the accessory.

2.  Turn the electronic unit over to remove or insert the 

batteries.

3.  Insert two new 1.5 V LR03/micro/AAA batteries. 

Make sure that you insert them the right way round 

(

see figure 7

).

4.  Put the electronic unit back into the frame. Make 

sure that “TOP” and the arrows on the back side of 

the electronic unit point upwards and that the clips 

on the mounting plate latch into the openings on 

the electronic unit.

5. 

Pay  attention  to  the  flashing  signals  of  the  LED 

while inserting the batteries (see „9.3 Error codes 

and flashing sequences“ on page 29

).

» After inserting the batteries, the accessory will per-

form a self-test (approx. 2 seconds). Afterwards, 

initialisation is carried out. The LED will light up 

orange and green to indicate that initialisation is 

complete.

Attention! There is a risk of explosion if the battery 

is not replaced correctly. Replace only with the 

same or equivalent type. Never recharge non-

rechargeable batteries. Do not throw the batteries 

into  a  fire.  Do  not  expose  batteries  to  excessive
