8 Error Handling, Faults and Repairing
8.1 Error Handling
8.1.1 First Action
If the device does not operate as expected the first step is always to check if the battery is fully charged. The “Low batter
y
LED” should indicate if the battery level is too low, but if you detect malfunction do always charge the battery as the first
step to get back to normal operation.

If the GNSS led is not lit after 3 minute of operation, try to bring the device outdoor to get free sight to the sky and check for
GNSS fix. Keep in mind that GNSS positioning is mainly intended for outdoor usage, and there is no guarantee that it will
always work in indoor environment

metal objects, low battery level can all be the reason why the device can't interact properly with the cellular network.
