Maintenance and cleaning

The device does not require you to carry out any
maintenance other than replacing the batteries
when necessary. Enlist the help of an expert to
carry out any maintenance or repairs.
Clean the device using a soft, lint-free cloth that is clean
and dry. You may dampen the cloth a little with lukewarm
water in order to remove more stubborn marks. Do not
use any detergents containing solvents, as they could
corrode the plastic housing and label.

General information about radio
operation
Radio transmission is performed on a non-exclusive
transmission path, which means that there is a possibil-
ity of interference occurring. Interference can also be
caused by switching operations, electrical motors or de-
fective electrical devices.
The range of transmission within buildings can
differ greatly from that available in the open air.
Besides the transmitting power and the reception
characteristics of the receiver, environmental
factors such as humidity in the vicinity have an
important role to play, as do on-site structural/
screening conditions.
