4.4 Device battery replacement
When using battery supply, the battery needs to be replaced periodically.
When you find the battery voltage from the data platform is lower than
13V, or the local battery is null, or there is no report for several days, it is
possible that the battery power is low and needs to be replaced. The
battery replacement procedure is as follows:
Step 1: open the top cover
Use a Phillips screwdriver to remove the fastening screws (12pcs) that
secure the top cover to the housing, and then open the top cover.
