GPS Receiver User’s Tip
1. GPS signal will be affected by weather and environment conditions, thus suggest to use the GPS
receiver under less shielding environments to ensure GPS receiver has better receiving performance.
2. When GPS receiver is moving, it will prolong the time to fix the position, so suggest to wait for the
satellite signals to be locked at a fixed point when first power-on the GPS receiver to ensure to lock
the GPS signal at the shortest time.
3. The following situation will affect the GPS receiving performance:
a. Solar control filmed windows.
b. Metal shielded, such as umbrella, or in vehicle.
c. Among high buildings.
d. Under bridges or tunnels.
e. Under high voltage cables or near by radio wave sources, such as mobile phone base
stations.
f. Bad or heavy cloudy weather.
4. If the satellite signals can not be locked or encounter receiving problem (while in the urban area), the
following steps are suggested:
a. Please plug the external active antenna into GPS receiver and put the antenna on outdoor or the
roof of the vehicle for better receiving performance.
b. Move to another open space or reposition GPS receiver toward the direction with less blockage.
c. Move the GPS receiver away from the interferences resources.
d. Wait until the weather condition is improved.

if the build-in backup battery is full-recharged.
