10 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 mainte-
nance 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 de-
tergents containing solvents, as they
could corrode the plastic housing and
label.
