The button in the battery case is the main switch for turning the headlamp on and off. The yellow button in the drive-by-wire switch is a standby switch. The blue button is a dimmer switch.

Depress the main switch for one click to turn on the headlamp and lock it. Depress the switch again to turn off the headlamp. When the headlamp is on, depress the standby switch to turn off the headlamp temporarily. Another depress will activate the headlamp again.

When the headlamp is on, double-press the standby switch quickly to switch to the flashing modes. Depressing the switch then will shift between the different outputs. The output sequence is as follows: Turbo > Low > Medium > High > Cycle.

In the flashing mode, depress the dimmer switch to shift between flashing modes: Strobe > Rescue Signal > Slow Flash > Cycle.

The HP20 will memorize the mode it's on when it is turned off.

If the HP20 will not be used for awhile, please depress the main button to fully turn off the power.
