Make sure to charge the G Pen Pro Vaporizer prior to use. Once the G Pen Pro is charged in full, press the power button five times. The unit will stay powered on for four minutes, but you can shut it off before that by pressing the button five times again.
The temperature will initially be set to the lowest setting, which is indicated by blue LED lights displayed directly below the power button. The front LEDs will blink while the G Pen Pro is heating to the selected temperature.
Once the G Pen Pro Vaporizer has reached the desired temperature, the front LED lights will light up solid, indicating that it is ready for use.
