at this point.
With the flashlight facing forward, snap the light into the charger until the contacts
snap into place.
The LED indicator changes to constant red indicating the light is properly inserted into

fully charged. At full charge, the LED indicator turns green.
The total time to fully charge varies depending on the remaining charge in the battery
pack.

To confirm a full charge, keep the unit in the charger and turn it on. The LED indicator
will change to red. Turn the unit off. If the light is fully charged, the LED indicator will
turn green. If not, it remains red until the charge is completed and the LED indicator
turns green. The unit will now be fully charged.
OPERATION

desired brightness level is reached, simply release the switch, and the light will remain in that
brightness mode. Press and release the top body switch to turn the light off.
