11. Cleaning / maintenance
11.1 Cleaning
Clean outer surfaces of product if necessary:
• with a dry, soft cotton cloth or
• a damp cloth and a little washing-up liquid or neutral cleaner.
11.2 Servicing /
maintenance
The product is maintenance-free apart from having to change the batteries.
Battery change
If the battery charge is low, the red and blue LED flash alternately three times when
the electronics are switched on by presenting a key.
The date and time are saved when the batteries are removed. This information is
reloaded when new batteries are inserted.
The clock stops for the duration of the battery change.
The batteries should therefore be changed quickly. If the time has to be exact to the
nearest minute, it can be set using the DIALOCK MDU after replacing the batteries.
The locking authorisations for the user keys are also retained after a battery change
and do not have to be reset.
