Maintenance and care

General operations

The unit is maintenance-free.
For proper care of the exterior surface of
the unit, a commercially available cleans-
ing fluid for electrical devices may be ap-
plied using a soft damp cloth.
DANGER
Danger to life by electrocution. Always
switch off the unit and disconnect the
grid power supply unit before cleaning
the unit, supplied components, or acces-
sories.
Note:
Do not use any aggressive or abrasive
substances or cloths which may damage
the surface.
The unit must not be exposed to water.
Your mobile navigation system was de-
signed and manufactured with great care
and should be treated with equal care. You
will enjoy your mobile navigation system
for a long time to come if you observe the
recommendations listed in the following:
• Protect your mobile navigation system
from water and moisture. If your unit is
exposed to moisture, switch it off im-
mediately and disconnect the power
supply. Allow the unit to dry at room
temperature.
• Do not operate your mobile navigation
system in a dusty or dirty environment,
and do not store it in such an environ-
ment.
• Do not store your mobile navigation
system in hot environments. High tem-
peratures can shorten the service life of
electronic components in your unit,
damage the rechargeable batteries, and
cause certain plastics to warp or melt.
• Do not store your mobile navigation
system in cold environments. During
operation, when the unit warms up to
operating temperature, moisture may
form internally, causing damage to elec-
tronic components.
• Do not drop your mobile navigation
system unit, protect it from shocks and
do not shake it. Improper handling can
damage components within the unit.
GENERAL OPERATIONS
• Never use corrosive or aggressive chem-
icals, cleaning solutions or aggressive
detergents for cleaning.
All of the above information applies
equally to the mobile navigation system,
the rechargeable battery, the mains charg-
ing, and car power adapters as well as all
accessories. Should one of these parts not
work properly, please contact your autho-
rized dealer. He will be pleased to assist.
