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.
In the case of CX2120 IP66, there is only one sealing ring on the side facing the
door.
