• The device is not a toy. Never allow children to play with
the device.
• Never touch the liquid that might leak from a broken liquid
crystal display. Contact with this liquid could cause a skin
rash. If the crystal display liquid should come into contact
with the skin or clothing, wash it immediately with clean
water.
• Never raise the sound volume level too high when using
the device with earphones. An excessive sound volume
level could cause damage to your hearing.
Car mount precautions
• Some countries prohibit the mounting of any electronic
device in any location on the vehicle dashboard. Be sure
to check the local laws for applicable mounting before
installing the car mount.
• Some newer vehicle models may have a heat reflective
shield embedded in the windshield. This may in some cases
obstruct the GPS signal reception. If you encounter this
problem in the vehicle, you need to purchase an external
GPS antenna.
• The heating and cooling cycle of a vehicle's interior will in
some cases loosen the adhesion of the suction cup. Check
the vacuum seal of the car mount for adequate adhesion
each time you use the unit, and reinstall it if necessary.
• If the car mount has problems staying on, clean the plastic
suction cup with alcohol, then reinstall. Moistening the
suction cup may help adhesion in some cases.
• To avoid extreme temperature from damaging the car
mount, remove the unit if the temperature inside your
vehicle exceeds 70°C (160°F).
• The dip in humidity and temperature at night may loosen
the adhesion of the suction cup. For this reason, as well as
for security, it is recommended that you remove both the
car mount kit and the NAV 350 when leaving your vehicle
overnight.
