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 again
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
