III. Key

1. Backlight control

Short press the key to turn on or off the backlight, the backlight has memory function, it can store the on or off state when power off.

2. Reset energy

Step1: Long press the key for 5 seconds until the number in energy display window flash, then release the key.

Step2: Short press the key again, then the energy value is cleared and exit the reset flashing state. 
If you don’t want to clear, then long press the key for 5 seconds again until the number doesn’t flash,
it means the energy value is not cleared and will exit the reset state.

3. Set power alarm threshold

Step1: Long press the key until the LCD screen display “SET CLr”, then release the key to enter the setting state

Step2: Power window display the current power alarm value and the last digit begin to flash, 
then you can short press to plus 1, when there is no operation over 3 seconds, 
it will switch the digit position automatically, the setting method is as same as the above.

Step3: After finish the setting, long press the key over 5 seconds will store automatically and exit, 
the range of active power threshold is 0.0～22.0kW
