A: Turn the rotary switch to the OFF state and disconnect the connecting cable.

Q. Why does the HP35R downshift to a lower mode after being used for a while and the higher mode cannot be selected?

A: There are two reasons:
1. Intelligent Overheat Protection
The headlamp will accumulate a lot of heat when used at high output levels for extended periods. When the headlamp reaches a temperature of 60°C/140°F or above, the headlamp will automatically step down a few lumens to reduce the temperature.

2. Low-voltage Warning
When the voltage level drops below the preset level, the headlamp is programmed to downshift to a lower brightness level until Low output is reached. When this happens in Low output, the headlamp blinks at Low output of Spot-and-floodlight mode to remind you to timely recharge the battery.
