Battery level indicator:Red indicator light:30% power;Green indicator light 1 is on:60% power;Green indicator light 2 is on:100% power;During charging, the corresponding indicator light flashes. After the battery is fully , all three indicators are always on.When the battery voltage is lower than 3V, the battery will be with a small current and the red indicator light will When the battery voltage is lower than 3V, it needs to be recharged.product does not work when charging Work indicator: 1.During operation, when the soldering iron tip is short-circuited or there is no output, the red indicator light will flash. 2.Heating process: First, after 12 seconds, the red light is on, the red light is off, and the green light is on, the user can operate. 3.It will stop working when the voltage is lower than 2.8V.4. When there is no operation, the self-discharge is lower than 25uA. Touch reset function: Press the power button six times continuously, the green light of the work indicator flashes, and the reset of the touch function is completed. Touch reset is a function to readjust the environment when the touch fails due to external interference (when touching to open or reset, do not put your finger on the touch button, otherwise it will not work) Turn off the touch function:Press the power button 8 times in succession.
