Gps Reception - SmartWitness KP1S User Manual

GPS RECEPTION

1. Activate the product in an area with a clear view of the sky &
without large buildings to improve GPS reception.
For commercial purposes GPS has an average range error of more than 15 meters
and the range error could be more than 100 meters depending on environmental
conditions like buildings and roadside trees etc.
2. The temperature range for optimum operation of the GPS receiver in
your car is -10 ~ 50°C.
3. When using the product for the first time or after a long period (more than
three days), it may take a little longer to recognize your current location.
It may take between five and thirty minutes to get GPS reception.
GPS reception may be impaired under the following circumstances:
1) If there is an object at the end of the GPS antenna.
2) If your vehicle has metallic elements on or in the windshield.
3) If equipment generating electromagnetic waves that interfere with the GPS signal
are installed in the vehicle e.g. other GPS devices including certain types of
wireless activated alarms, MP3 and CD players and camera alarms using GPS.
4) If you are using a receiver connected by a cable, electrical interference can
be avoided by simply changing the location of the KP1S installation.
5) On heavily overcast or cloudy days, if the vehicle is in a covered location such as
under a bridge or raised roadway, in a tunnel, an underground roadway or parking
area, inside a building or surrounded by high-rise buildings.
6) If GPS signal reception is poor, it may take longer to locate your current position
when the vehicle is moving than when it is stationary.
