How to solve the common faults of electronic patrol?

1, stainless steel waterproof patrol fault processing:

1) Inspector does not work

First check whether the battery is in poor contact. Otherwise, the battery power may be insufficient and the battery needs to be charged.
If you ignore the low-voltage indication and continue to use it, it will be fully discharged and the inspector will stop working.

Charging requires a longer charging time than usual when fully discharged.

After the above steps, it still cannot be charged or the patrol meter still cannot be used normally. Please contact the supplier.
Note: The patrol meter data will not be lost after full discharge. The battery is strongly impacted, which may result in damage to the battery and may not work properly.

2) Cannot confirm the data transmission cable works normally

Make sure the data transmission cable is connected to the computer and data patrol.

If the computer is using a communication port between the Internet or a PC, port conflicts may occur. At this time, select other ports through the parameter settings in the system management.
