NOTE
Please pay attention to the following when using lithium batteries:
The type-specific discharge behaviour of lithium batteries (considerable
voltage drop at the end of the life time) may cause that a low battery is indicated
at the terminal only for a short period or not at all.
This may cause a short-term malfunction of the terminal.
We recommend changing the batteries before the winter months with the
outdoor version.
The clock continues to run for up to 5 minutes without batteries. In spite of this, the
time should be checked and set if necessary using the MDU after a battery change.
The locking authorisations for the user keys are also retained after a battery change
and do not have to be reset.
For step-by-step instructions "Battery change" see
illustrations starting on page 71.
