13. Maintenance and Cleaning
The product is maintenance-free for you. Servicing or repair must only be carried out
by a specialist or specialist workshop. There are no parts that require maintenance by
you inside the product. Therefore, never open it (except for the procedure described
in these operating instructions for inserting or replacing the rechargeable batteries or/
and assembly).
A dry, soft and clean cloth is sufficient for cleaning.
Do not put too much pressure on the display; this can cause scratch marks, failures of
the display or even destroy the display.
Dust can easily be removed with a long-hair, soft and clean brush and a vacuum cleaner.
Never use any aggressive cleaning agents, cleaning alcohol or other chemical solutions,
since these may damage the casing (discolouration) or even impair function.
