The reason why the fascia gun cannot be turned on:
The main reason is that the temperature is too high. If the fascia gun is used in an environment above 40 degrees Celsius, the fascia gun may be punished for overheating protection, and the host will not be able to boot normally.
Solution: Stand still for 2 hours in an environment below 40 degrees Celsius, and then turn it on for use.
Why is the battery level at “0”:
When the battery is dead, if the user does not charge for a long time, the battery will produce low-power protection, which is collectively referred to as over-discharge protection. At this time, the fascia gun cannot work normally if the power is turned on again.
Solution: Keep the power off, connect the charger to let the fascia gun enter the charging mode, and then turn on the fascia gun after it is fully charged, and it will work normally.
