Operations

This light has 3 main levels, High, Medium, and Low. The High and Medium levels have two sub-levels.

• When the light is Off:
  • One short-click turns on the light to High.
  • Press and hold (for over 0.6 seconds) turns on and cycles through the light to Low and then Medium and High. Release at the desired level.
• When the light is On
• One short-click turns off the light.
• Press and hold cycles through to Low and then Medium and High. Release at the desired level.
• Double-click to toggle between the two sub levels: M1 and M2 in Medium and H1 and H2 in High. The selected sub levels are memorized and will come back on when you go back to that main level. Sub level settings are memorized when the light is turned off and through battery changes.
