The device does not require you to carry out any maintenance other

repair to a specialist.

en the cloth a little with lukewarm water in order to remove more stubborn
marks. Do not use any detergents containing solvents, as they could cor-

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