Troubleshooting

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.

• It may because you did not make valid operation (press is too

light to start). 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 unit 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 37 on “ Turning on”.

2. Battery choices

You can use alkaline battery or rechargeable battery. But if you use

rechargeable battery, the unit can not show you the correct information

on the batteries condition.

• Make sure you are operating outdoors, not in a house or building.

• See if the sky is clear and open, it will influence the satellite signals

field around you or the unit which can interfere the normal work,

such as wireless radio station, radio tower or high-voltage wires and

cables, and etc.

4. GPS handheld receiver has water outside and inside

Wipe down the water outside of the unit 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 unit

by yourself.

5. Though in open area with clear sky, GPS handheld receiver can not

or supplier.
