Maintenance and cleaning
The device does not require you to carry out any maintenance other
than replacing the battery when necessary. Enlist the help of an
expert to carry out any repairs.
Clean the device using a soft, lint-free cloth that is clean and dry. 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 possibility of interference occurring.
Interference 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
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.
