When the indicator is connected by USB, the battery charging runs automatically. The indicator can detect the
charging status and continues charging until the battery is fully loaded. Then the charging process stops
automatically. It is not recommended to interrupt the charging process before it is automatically stopped. The
charging process is finished when the display message "CPM 500 charging..." has disappeared.

the unit to charge the battery for 90 minutes by pressing both arrows
+
at the CPM 500 unit
for 2 seconds (Forced Charging Mode).
Note:
It is not recommended to use the Forced Charging Mode when the battery charge condition is more than
40%, due to the risk of overcharging. Please see chapter 5.2 for a description how to check the charge state.
