5. Maintenance of GPS Navigator
GPS navigator will be a reliable navigation and entertainment companion if protected by right
methods. Please follow the instructions below to ensure your GPS run smoothly for a long time.
• Protect screen: Don’t press the screen with strength or you will destroy it. Please use the stylus
to operate the navigator and spray a little glass cleaner on the soft cloth to clean the screen, don’t
spray on the screen directly.
Note: Be sure to turn off the GPS navigator before cleaning;
• Drop or strike will cause damage to high-precision components.
Note: Accidental damage is beyond our responsibilities.
• Don’t use it under such environment: Temperature change abruptly (high temperature above 60°,
low temperature under-10°), high voltage, dusty, electrostatic interference, avoid any corrosive li-
quid and dip into any liquid.
• Avoid radiated interference: The radiated interference from other electronic products will affect the
display and it will be normal after suppressing the interference source.
Note: If you carry the unit by air, please put the GPS together with
your luggage to pass the X-ray detection system. Avoid scanning
by the magnetic head detector (at the passage used for passing) or
the magnetic bar (held by the security checker), or it will destroy the
system date in the unit. We will take no responsibility for it.
• Avoid direct, intense light: Don’t use the GPS navigator in high light and ultraviolet radiation in
order to increase the using life.
