Reticle Illumination; Illumination Knob/Battery Compartment - Primary Arms GEN II Instruction Manual

RETICLE
ILLUMINATION
The illumination knob on the top of
the scope is marked with numbers of
increasing brightness from 1 to 5 in each
direction from 0 or "off". There are two
"off" settings, divided between 5 red
partial illumination settings and 5 green
partial illumination settings. The knob
cap unscrews counter-clockwise, holding
a CR2032 battery with the positive (+)
side facing towards the cap. Reticle
illumination at the lower settings is
useful in low light situations like sunrise
and sunset. The highest two settings
are "daylight bright" settings. Using
these settings in low light situations
will overpower your eye's ability to
see the target and make the reticle
appear distorted. The right amount of
illumination creates a clear contrast
between the reticle and your intended
target, without straining the eye.
