Troubleshoot

Error in power on self-testing: the charger can automatically carry out a self-testing when

connected to a power supply. A self-testing error warning sound should be heard when the

charger is connected to the battery; power on after removing the battery for 5 minutes.

Error for abnormal battery connection: pull out and plug in the battery again to ensure all

connections are reliably contacted; if the error reminder continues, please check whether the

metal parts on the battery interface are oxidized or burned resulting in unreliable connection.

Error for unstable power voltage: check whether the battery socket is reliably connected, and

whether the power of electric supply can match the input requirement of the charger. If

capacity of PSU is less than charger's Max power, please adjust the max input power to match

the power of electric supply in the system fault menu of the charger.
