Protective Features
An electronic protection circuit prevents damage if charging clips
are short circuited. The first bar on the display blinks if this
occurs.
An electronic protection circuit prevents damage if the charging
cables are connected with reversed polarity. The
and
symbols blink alternately on the display if this occurs.
If the room temperature increases, the charger will reduce the charging current and
interrupt the charging operation if necessary. As soon as the unit cools, charging
resumes.
If the battery fails to reach a certain voltage value within a pre-
determined time, the charger will automatically cut out.
After automatic cut out
1. Unplug the charger from the AC wall outlet
2. Disconnect the charger from the battery
3. Investigate the reason for the safety cut out
