Thermal protection circuit: Lezyne LED Lights are protected by a thermal detection system. If the
operating temperature of the light is too high, the light will automatically change to the lowest setting.
To return to normal mode settings, turn off the light and allow it cool until the ambient temperature is
below 45°C (113°F).

To charge battery:
1. Confirm light is turned off.
2. Release Rear Battery Door Latch and open Rear Battery Door.
