Eyecup Adjustment
The eyecups on the Droptine HD binoculars are adjustable to ensure a
full field of view. Twist the eyecups up for normal use, or turn them down
when wearing eyeglasses or sunglasses.
IPD Adjustment
The Inter-pupillary Distance or IPD is the distance between the center
of your left and right eye. Setting the IPD is simple and easy. The two
binocular barrels pivot on a hinge to match your eyes. Move the barrels
in and out until you see a single bright image with no shadows.

Focusing the Binoculars
Your Droptine HD binoculars can be set up for your eyes with two
simple steps:
1. Find the diopter adjustment ring located below the right eyecup.
Start with the diopter adjustment set to zero with the two hash
marks aligned.
Focus on an object approximately 25 yards away. Place the lens
cap on the objective lens of the right side and use the center focus
knob to bring the object into sharp focus. Leave the center focus
knob in this position while you adjust the diopter in step 2.
2. Uncover the objective lens on the right side, and cover the left
objective lens while looking at the same object. Next, turn the
diopter ring to bring the object into sharp focus. To fine tune the
focus, you might have to turn the diopter slightly past sharp focus
and then back again. The diopter focus only affects the right side.
Once you have the diopter focused, you can now use the center
focus knob for all viewing and adjustment.

Care & Maintenance
The Droptine HD binocular is fully waterproof and fogproof. 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 can 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.
Position the binocular 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 Burris optic will provide reliable performance given reasonable
care and treatment. All moving assemblies are permanently
lubricated. Only occasional cleaning of the outside of the binocular
and the exterior lenses is required. Never disassemble your
binocular. Disassembly by anyone other than our factory will
void the warranty. If you have any other problems, contact Burris
Customer Service.
