NIGHT vISION MODE: The MCS is compatible with Generation II, III, III+
and IV+ Night Vision Devices. In the night vision mode, the reticle bright-
ness is low enough that when viewed with a night vision device, the reticle
image does not bloom.
To activate night vision mode, turn the sight on. Once the sight is on, press
and hold the left button for two (2) seconds. The reticle can now be seen
when a night vision device is placed behind it. To exit night vision mode,
press and hold the left button for two (2) seconds; the sight will return to
daytime operating mode.
pOWER CONTROL: Maximum brightness, used in conjunction with the
manual override of all automatic controls and the 20 MOA ring mode, uses
more power than the auto-brightness 3.5 MOA dot mode. To maximize bat-
tery life, the MCS will automatically switch to 3.5 MOA dot auto-brightness
mode after 20 minutes of inactivity when in 20 MOA or max-brightness
mode.
REpLACING THE bATTERY: If the reticle flashes after the sight is turned on,
the battery should be replaced. To remove the old battery, loosen the two
flathead screws on the battery compartment using a small flathead screw-
driver or a similar tool. Pull the battery compartment out. To avoid losing
the screws, do not remove them completely. Remove the old battery from
the compartment and replace
it with a new CR2032 battery,
with the negative end facing
up (as shown on the side of
your sight). Replace the bat-
tery compartment and tighten
the screws until they are se-
cure. Do not over-tighten the
screws.
pROTECTIvE LENS COvER: The MCS is equipped with a protective lens
cover that is necessary for several reasons; the cover provides protection
for the lens and laser diode, keeps the optical path free of debris, and pre-
vents unwanted light from obscuring the sight’s image and reticle.
The cover has three configurations. When the sight is not being used, a tab
on the lens cover blocks the photo sensor. This matches the sight in dark-
ness, which prolongs battery life and protects the lens while it is not in use
(see Figure 5A).
In its normal operating mode, the lens cover is placed on the top of the
CR2032
