Superseding the legendary EagleTac M2
series,
the new EagleTac M3C4 packs 11
Watt of high output LED power in a com-
pact flashlight body. The M3C4 pushes 800
out-the-front lumen at the turbo mode
(SST-50 and triple XP-G R5 models) and
offers a maximum of 100+ hours regulated
output at the low output mode (15 lumen).
The single-handed operational switch
behind the head allows users to access all
functions easily without compromise.

Light activation and usage
Dial the operational switch behind the
head to toggle the flashlight on/off. Dial
the switch clock-wise to increase the
brightness output and counterclock-wise
to dim it. To access the hidden
strobe/S.O.S./beacon output, turn the ring
rapidly from the turbo mode to the
off/standby mode, then back to the turbo
mode within 1.5 seconds.
To replace batteries, unscrew the head and
unload the battery tray. Insert new batter-
ies (refer to the terminal sign on the
battery tray) and load the battery tray with
the metals connectors toward the front.
WARNING -
Lithium and Li-ion batteries
can explode or cause burns if disas-
sembled, shorted, or exposed to high
temperature. Do not mix with used or
other battery types or install backwards.
ET55 Filter System - A diffuser filter is
included in this package. The optional
YRGB kit includes yellow/red/blue/green
color coated filters. Unscrew the bezel ring
and attach the glass filter to use.
Troubleshooting - Flashlight does not turn
on or does not stay on.
1) Use new batteries or fully charged
rechargable batteries. Old rechargeable
batteries may not hold a charge.
2) Ensure the batteries are making good
contact with the battery tray.
3) Ensure the batteries are inserted in the
correct direction in the battery tray.
