Replacing the sealing ring
ATTENTION
Damage to the sealing ring caused by improper handling
Do not use any sharp objects and do not stretch the sealing
ring more than what is required for mounting.
Prerequisite: Knob sleeve is removed (see chapter 7.2.1 Replacing the battery,
page 19)
If the knob sleeve is open, both sealing rings are visible. The smaller one is
on the side away from the door.
To remove the sealing rings, hold the respective sealing ring on one side with
the thumb, while pushing on the opposite side with the fingernail of the
middle finger. The sealing ring can now be grasped by the index finger.
Insert a new sealing ring.
