Precaution and Notice
The PND is used only as a navigation aid. It is not for precise measurement of direction,
distance, location or topography. The user must follow all traffic signs and local regulations
along the roads.
GPS satellite signals cannot pass through solid materials (except glass). When you are in a
tunnel or building, GPS position is not available.
At least 4 GPS satellite signals are needed to determine the current location. Signal reception
can be affected by situations, such as bad weather or dense overhead obstacles (e.g. tall
buildings).
Other wireless devices in the vehicle might interfere with the reception of satellite signals and
cause the unstable signal reception.
If system haltes, please press the power button to restart the device.
When you get out of the car, please do not leave your PND on the dashboard or subject to
direct sunlight. The overheating of the battery may cause malfunctions or danger.
Please do not fix the device where the driver’s field of vision is blocked.
