the electronics are switched on by presenting a key.

Malfunction due to low battery charge!
Problem-free operation is only ensured if adequately charged batteries
are used.

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.
