Q. The data logger does not log data even the power is on.
A. Possible reasons:
1.
Power on log (see NaviLogManager) is turned off.
2.
It’s in management mode. It logs data only in recording mode. If a user runs
NaviLogManager, stops recording, terminates NaviLogManager then the data logger is
still in management mode.
3.
The GPS signal is not well-received (e.g. in basement) and thus not able to get the
position fix. There is no new logging data while it can not fix its position.
4.
Value of record options (by distance, by time period, by speed) is big and still needs to
wait for it to meet the criteria.
Q. Turn on power of BB-100 battery bank, no LED light on the mounted GR-312.
A. The power of battery is used up. Please charge it immediately.
Q. When using NaviLogManager, it shows communication error.
A. NaviLogManager supports both wired and wireless communications to manage GR-312.
However, if two NaviLogManager are running to manage the same GR-312 the result is
unpredictable. The simplest way to solve this problem is to cycling GR-312 and
NaviLogManager. That is to say, to power off and then power on GR-312, to terminate and
run again one NaviLogManager only.
