Compact Tactical Weapon-Mounted Light
INSTALL THE BATTERY
SAFETY WARNING: ALWAYS REMOVE THE LIGHT FROM ANY HANDGUN BEFORE CHANGING
THE BATTERY.
Unscrew and remove the bezel.
Insert the included CR123A battery with the positive(+) end fi rst.
Replace the bezel and tighten until fully seated. You will feel a resistence as you tighten past the
lockout detents. Continue tightening until the dot on the bezel aligns with the ON position.
SAFE MODE: To disable the battery and prevent the light from unintended activation, turn the bezel
counter-clockwise until the mark on the bezel aligns with the OFF position.
INSTALL THE TCM ONTO YOUR HANDGUN
NOTICE: Your TCM has been pre-confi gured with the C1 Modular insert. If the fi t is not correct for your
specifi c handgun model, use the Allen wrench to switch to the C2, C3 or C4 insert that works best for
your fi rearm. Correct key installation allows the light to slide close to the trigger guard with only a slight
visible gap. Reducing the gap ensures proper fi t with most holsters.
Push inward on the rail clamp tension thumbscrew to fully open the rail clamp.
Align the insert tab with the appropriate slot on the tactical rail of your handgun. Rotate the rail
clamp of the TCM onto your handgun's rail so that the insert is fully seated in the slot.
While making sure that the insert remains fully seated in the slot, hand-tighten the rail clamp
tension thumbscrew.
Use a coin to fully tighten the tension thumbscrew.
CAUTION: PERIODICALLY CHECK THE ALLEN SCREWS ON THE INSERT AND THE RAIL CLAMP
TENSION THUMBSCREW FOR TIGHTNESS.
