Cleaning and maintenance
7.1

Clean the knob module only with a commercially available household
cleaning agent and a damp cloth.
Do not use any abrasive or caustic cleaning agents.
7.2
Maintenance
7.2.1
Replacing the battery
CAUTION
Danger of injury caused by improper use
Do not charge, open or heat the battery.
Always replace discharged batteries with new batteries.
Pay attention to the correct polarity when inserting the
batteries.
Change the battery only with the door open. As long as the battery is removed,
the knob module cannot engage and thus cannot open the door.
Hold the battery change card in front of the knob module – the knob module
enters the battery change position. Before this step, it may be necessary to
‘wake up’ the knob module by turning it.
Press in the now unlocked sleeve-locking pin of the knob module with the
Battery change tool and simultaneously pull out the sleeve.
