Open the G Pen Pro mouthpiece, load your dry herbs in the chamber and close the mouthpiece back. Then simply turn on by pressing the button five times, it will start heating up automatically. Once one, hold the button down and select a temperature. You will see different LED lights colors. The available settings are:
Low (Blue, 375F)
Medium (Green, 400F)
High (Red, 428F)
The lights will blink while the device is heating up and stop flashing once it’s ready to use.
The number of lights turned on will show you the current battery level (the lower the battery goes, the fewer lights you will see). That is a great thing, nothing spectacular but really helpful and clear to see right away. Once the lights stop blinking, pull through the mouthpiece to start vaping.
