Illuminated Reticle Adjustment
Rotary Illumination
Illumination makes it easier to see the reticle
in low light conditions. The intensity of the illu-
mination is controlled by a rotary illumination
switch located on the left side of the adjust-
ment turret. The switch has 10 intensity levels
and an “Off” position in between each level.
The reticle is powered by a 3-volt lithium cell
battery #CR2032.
To install a new battery,
simply unscrew the
battery cap on the
rotary switch and install
the new battery flat side
(+) up. It is advisable to
remove the battery for
long-term storage (over a month).
Care & Maintenance
RT-6 riflescopes are fully waterproof and fog-
proof. In the event that the lenses are subjected
to dust, dirt or mud, follow these steps to clean
and protect the lens surface. Failure to remove
grit before final cleaning is sure to damage lens
coatings. Coarse dirt/debris must be removed
from the lens surface. The most convenient way
to clean a lens surface is to use a Lens Pen. Po-
sition the scope so particles will fall away from
the lens, and then use the Lens Pen or soft brush
to gently whisk away the debris while blowing
on the lens to dislodge the particles. For heavy
dirt, like dried mud, use a spray of clean water
or lens cleaning fluid to remove the dirt.
Your RT-6 riflescope will provide reliable perfor-
mance given reasonable care and treatment.
All moving assemblies are permanently lubri-
cated. Only occasional cleaning of the outside
of the scope and the exterior lenses is required.
Never disassemble your scope. Disassembly
by anyone other than our factory will void the
warranty. If you have any other problems with
your riflescope, contact Burris Customer Service.
