12 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 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 luke-
warm water in order to remove more stubborn marks.
Do not use any detergents containing solvents, as they
could corrode the plastic housing and label.
