Turning the Unit On
Press and hold the Right Key for 3 seconds, until
unit LCD displays “on”, the buzzer beeps, and the
green LED is on. After power on, the unit enters a
warm up and self-test sequence, and then enters
normal mode. Once the unit is turned on, it runs
continuously until the remaining life time ends,
and cannot be turned off.
