1. Turn on/off back light
the button cell is designed to maintain the RTC(Real-Time-Clock) chipset inside the Pm90
Please note that back light consumes much more energy than RTC chipset itself, so we set a
switch to turn off the back light if back light is not necessary during cell power supply. Please
be advised that turning off the back light will expand battery life sharply.
