If the device is to
be left unattended
for a prolonged
period of time (e. g.
during a vacation)
or if a thunderstorm
is forecast, pull
the mains adapter

any additives. In case
of stubborn marks,
a mild soap solution

remove dust or small
amounts of dirt with
a dry, smooth leather
cloth.
• Use a damp cloth to rub
off stubborn dirt. Make
sure that no liquid pene-
trates the housing.
• Then immediately wipe
the damp surfaces off
with a soft cloth without
applying pressure.
