SPECIFICATIONS

KIT CONTENTS:
• XC1 WeaponLight
• AAA, Rechargeable NiMH Battery
MOUNTING XC1 TO A HANDGUN
XC1’s rail-mount bolt should be sufficiently loose before sliding the
XC1 onto the rail (Fig. 1). To further loosen, if needed, turn screw on
rail-mount bolt counterclockwise with a 3/32” Allen wrench until
there’s sufficient clearance to slide the XC1 onto the rail and over the
cross member. Once properly positioned (looking through the indexing
cutout) tighten screw (clockwise) so the bolt rises into the locking notch
thereby securing the light to the firearm.
NOTE: Minor centering of the XC1 onto the rail may be required for
an optimum fit. The bolt interface requires only hand-tight tension
and will not back out from recoil. Do not over-tighten.
REPLACING THE BATTERY
Confirm that your firearm is unloaded. Do not place hands in front of
muzzle when replacing and installing the battery in your XC1-B. Remove
the battery cap by turning any of starred slots counterclockwise with
coin or flathead/slot screwdriver (Fig. 2). Remove spent AAA battery
and replace with a new AAA battery. Once new battery is in place with
positive terminal facing outward, simply retighten the battery cap (by
turning cap clockwise) and reinstall the XC1 onto the handgun (see
above).
NOTE: AAA NiMH batteries are recommended for optimum output
and runtime. AAA lithium and alkaline batteries can also be used
but with less runtime.
ACTIVATING THE XC1
Your XC1 was designed to allow support-hand activation in both
momentary-on and constant-on modes when firing right- or left-
handed (see Fig. 3).
TOGGLE SWITCHING
Momentary-on activation Depress and hold either toggle switch for
more than a tenth of a second or as long as needed to momentarily
activate the XC1-B. Release to turn off.
Constant-on activation with toggle switches: The XC1-B is
programmed for constant on activation by a quick tap and release
action via either toggle switches.
NOTE: The light will not activate when these rear switches are
pushed upward or side-to-side. This intentional design-feature
minimizes unintended activation when drawing or holstering.
SLIDE SWITCH ACTIVATION
Constant-on activation, with slide switch: Constant-on activation
with toggle switches: The XC1-B is programmed for constant on
activation by applying a quick tap and release action to either toggle
switch. Depress either toggle switch to turn off the light.
NOTE: If the XC1-B is initially activated to constant on using the
slide switch it can only be turned off by moving the slide switch
to the OFF position. The toggle switches cannot override the slide
switch when it is moved to the ON position.
MAINTENANCE
Use a clean, dry cloth to wipe off body and window. Periodically clean
and lubricate threads. Apply a thin coat of non-migrating, silicon-based
lubricant to battery cap o-ring (do not use petroleum-based lubricants
which can harm O-rings). For additional tips on maintaining your SureFire
illumination tool, visit www.surefire.com/faqs-maintenance.
