1. The screen is blank after you press the POWER keypad.
• Wrong batteries installation or no enough power. Check to insure that the batteries are installed
correctly and that the battery terminals are clean. Or replace the batteries.
• You may did not make valid operations(press is too light to start
E-trace). Please press
POWER key again till the unit responses and hear a sound “B” and see the welcome page.
• If you hear a sound “B”, then the
E-trace is already turned on. You need to adjust screen
contrast until you can recognize the words on the screen.
Please take a reference in page 3 on “ Turning the
E-trace on”.
2. Battery choices
You can use alkaline battery or rechargeable battery in
E-trace. But if you use rechargeable battery, the
E-trace can not show you the correct information on the batteries condition.
3. Unavailability of satellite signals for long time
• Make sure you are operating the
E-trace outdoors, not in a house or a covered building.
• Ensure the sky is clear and open since it will influence the satellite signals reception.
• Check your surroundings, there may be some electric or magnetic field around you or the
E-
trace which can interfere the normal work of E-trace, such as wireless radio station, radio
tower or high-voltage wires and cables, and etc.
4. The GPS_DESIGNER has water outside and inside
Wipe down the water outside of the
E-trace with clean clothing. Put it in a windy place without direct
sunshine and dry the inside. Then try to turn it on again to see if it works well. If it is still not good,
please contact local maintenance agency. Never try to open the
E-trace by yourself.
5. Though in open area with clear sky, the E-trace can not track satellite.
• It’s most because the
E-trace had worked indoor for long time and been brought outdoor
directly. Please turn off the
E-trace outdoor and restart it.
• The
E-trace is damaged. Please contact local dealer or supplier.
6. The
E-trace dropped or collided
Check the appearance completeness of the
E-trace. Contact the local maintenance agency if you find the
E-trace does not work well.
