pure test program and can not be used for navigation or orientation.

Please inform yourself directly at u-blox about the different versions and the possibilities of

this extensive test software: http://www.u-blox.com/en/evaluation-tools-a-software/u-center/u-

center. html.

Explosion on contact with fire!

Do not permanently expose the receiver to temperatures of over 60°C (140°F).

6. Possible sources of error and their elimination

6.1 You still don’t get a satfix.

The BT-821G needs up to 20 minutes for its first satfix on another continent. To get a satfix

the view to the sky must be unobstructed. Move the BT-821G as far as possible from the wall.

A house wall reflects the signal strongly and contributes to the satfix time delay.

6.2 Without an active Bluetooth connection, the BT-821g switched off automatically after

about 15 minutes. Just turn it on by pressing and holding the On / Off button again.

The Navilock repair center tries to be as obliging as possible, so please tell us the real reason

for the defect. During the error analysis, we can generally detect if the cause for the defect was

an external cause, water damage, fall, over-voltage or the wrong handling of the unit.

Failures are often the result of little causes. It is not always necessary to exchange the product

immediately, because this will not solve the cause of the failure if it is not a GNSS hardware

problem.

Before visiting your dealer, please contact the Navilock support center. They will try to help you

quickly and without further ado, so that the circumstances of an exchange, which might in any

case be unnecessary, are avoided.

In this case, please write down a detailed description of the error, add this information to your

end device and the software used in this device, as well as the operation environment (operating

system, service pack version, CPU type, storage size, hard disk drive and interface etc.), and
