Operation:
Turn on/off by fully pressing the reverse clicky switch (i.e. click needed to turn on).
With the head slightly loosened, you get one of five possible modes. Soft-press the switch to advance through Firefly,
Low, Medium, High, and SOS, in repeating sequence. The light has mode memory, and retains the last setting used
when you come back into the head loosened state.
With the bezel fully tightened, you get Turbo. Soft-press to advance to rapid Strobe (soft-press again or turn off to get
back to Turbo). There is no memory for the head-tightened mode - you always get Turbo on activation with the head
tightened.
