Initial Setup
Fill the Water Chamber

Power On
Press the power button 5 times rapidly. The LED indicator will light up to confirm the device is ready.

Three Operating Modes
The G Pen Roam offers three distinct modes:
Auto Mode
Press and hold the button — the device heats automatically to the set temperature and stops when the cycle completes. Best for beginners who want a consistent, hands-off experience.
Manual Mode
Hold the button to heat, release to stop. This mode offers the most control, letting you manage heat delivery in real time.
Max Mode
Automatically heats to the maximum temperature. Best for users who want dense vapor and maximum extraction.

Temperature Settings
Temperature range: 600-800 F in 25 F increments using the buttons on the device.
| Level | Temperature (F) | Characteristics |
|---|---|---|
| Low | 600-650 F | Flavor-focused, light to moderate vapor |
| Medium | 675-725 F | Well balanced, good flavor with moderate clouds |
| High | 750-800 F | Dense vapor, maximum extraction |

How to Use
1. Power on the device and select your desired temperature.
2. Use the Dabber Tool to place a small amount of concentrate (rice-grain size) into the Quartz Tank.
3. Close the device cap.
4. Select your mode (Auto/Manual/Max) and activate.
5. Wait for the device to reach temperature (approximately 20-30 seconds).
6. Draw slowly and steadily through the mouthpiece. The water filtration system cools and smooths the vapor.
