MAINTENANCE AND CLEANING

Maintenance or repair should only be
performed by a qualified technician
or workshop. There are no parts in-
side the product that require your
maintenance.
For cleaning the outside, a dry, soft,
and clean cloth is sufficient.
Do not press too hard on the front
glass or casing, as this could lead to
scratches on the surface.
Dust can be easily removed with the
help of a long-haired, soft, and clean
brush and a vacuum cleaner.
Do not use any aggressive cleaning
agents, cleaning alcohol, or other
chemical solutions, as these could
damage the casing or even impair its
function.
