8.2 Procedure  
1.  Hold the assembly/battery tool against the knob so that both nibs fit into the open-
ings on the ratchet disk (if necessary turn the knob until the nibs slot into the open-
ings). 
 Attention:
 The assembly/battery tool must be held flush against the inner surface of 
the recessed grip ring to fit into the ratchet disk. 
2.  Hold the knob and carefully turn the assembly/battery tool 30° in a clockwise direc-
tion (until you hear a clicking noise). 
3.  Remove the assembly/battery tool from the knob. 
4.  Slide the recessed grip ring back towards the door until it slips off the knob. 
5.  Hold the recessed grip ring, turn the knob approx. 10° anti-clockwise and remove. 
6.  Carefully remove both batteries from their bracket. 
7.  Hold the two new batteries with plus poles facing each other and slide them into 
the bracket (please replace the batteries as quickly as possible). Make sure you 
wear clean, grease-free gloves when handling new batteries.
