7.3 Troubleshooting

Please refer to the troubleshooting methods mentioned below.
Please read the "LED indication" of this manual in Chapter 6.2 before troubleshooting to
prevent false operations. For example, it doesn't indicate the battery is faulty if the ALM
alarm red light on the front panel is blinking or constantly on. When there is an "alarm"
indication, it usually works well and needs no troubleshooting. When there is "protection"
indication, the battery will work normally automatically after "protection" status is
released.
Do not repair the battery if no authorization from Pytes!
