6.1 Inserting batteries

The battery compartment (E) is located on the base
unit. To open it, you must remove the base unit from
the wall mount (F).
The range of transmission within buildings
can greatly deviate from open air distances.
Besides the transmitting power and the
reception characteristics of the receiver,
environmental influences such as humidity in
the vicinity and local structures also play an
important role.
