If you get lost, or if you want to auto-calibrate the temperature sensor, do a Factory Reset. The process
for this is:
- Loosen body tube
- Hold button
- Tighten body tube
- Keep holding button for about 4s
The light should flicker while getting brighter, then briefly burst to full power. Hold until it reaches full
power to do a reset, or let go of the button early to abort.
