LED Flashlight.

The GB40 has an integrated ultra-bright LED flashlight. It has seven (7) light modes that effect its performance and longevity: 100%, 50%, 10%, SOS, Blink, Strobe, and Off. To turn the

ﬂashlight “On” and “Oﬀ”, use the Power button with the light bulb icon. Press once to turn the ﬂashlight “On” at 100% luminosity, again for 50% luminosity (within 3 seconds), again for

10% luminosity (within 3 seconds), again for SOS (within 3 seconds), again for Blink (within 3 seconds), again for Strobe (within 3 seconds) and gain for “Oﬀ”. If a light mode is not

selected within 3 seconds, it will remain “On” in the current light mode, and the next selection will turn the ﬂashlight “Oﬀ”. Depending on the mode selection, the GB40 will have

various levels of output and runtime. Selecting a lower power level when using the GB40 for extended periods of time will prolong battery life.

Modes: 100% > 50% > 10% > SOS > Blink > Strobe > Off

Energy Saving Auto Shut Off.

The GB40 has a built-in energy-saving feature that will automatically turn the unit off after seven (7) hours. To continue using, simply power on the unit again.
