Maintenance and care
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.
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.
• 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.
 
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.
