Maintenance and cleaning

11 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. You may dampen the cloth a little with lukewarm
water in order to remove more stubborn marks. Do not
use any detergents containing solvents, as they could
corrode the plastic housing and label.
Check that your product is safe from a technical
point of view (that the housing is not damaged, for
example) on a regular basis. If you have reason to
believe that it is no longer safe to operate the de-
vice, put it out of service. Remove the battery pack
to safeguard the device against unintentional op-
eration.
Safe operation may no longer be possible if the device:
• shows signs of external damage,
• no longer functions,
• has been stored under unfavourable conditions or
• has been exposed to severe transport conditions.
If not used for any length of time (e.g. when in
storage), remove the batteries to avoid damages
caused by leaking, etc.
