The main on/off switch turns the light on and off. When the light is off,
1. Pressing and holding the paddle causes a fast strobe. Releasing the paddle causes the strobe to stop and the light to go off.
2. Pressing the on/off switch causes the light to turn on in a moderate strobe. While on, pressing the paddle has no effect, and the light stays in the moderate strobe. Pressing the on/off switch again causes the light to turn off.
