Turning on/off Intelligent Brightness Downshifting Function
On: With the light switched off, press and hold Switch A for 6 seconds, and the headlamp will flash twice
at the Low output of Floodlight mode, indicating that the function is enabled.
Off: With the light switched off, press and hold Switch A for 6 seconds, and the headlamp will flash eight

Intelligent Brightness Downshifting
When the lamp head is close to an illuminated object (about 2.36''/60 mm) for more than 1.5 seconds,
the headlamp will automatically downshift the brightness level to Low output to avoid potential burns
caused by high temperature(s). When the lamp head is moved away from the illuminated object for more
than 0.8 seconds, the headlamp will automatically recall the previously used output level.
