ABOUT THE RETICLE
The vertical scale (reticle) visible through the right half of the binocular
allows you to calculate distance to an object if you know its height, or
to calculate the height of an object if you know its distance from you.
Detailed instructions for using the reticle are provided in later pages of
this manual.

IMPORTANT
AFTER EXPOSURE TO SALTWATER OR SPRAY, FLUSH THE
BINOCULARS THOROUGHLY WITH FRESH WATER AND WIPE DRY.
AVOID EXTENDED EXPOSURE TO BRIGHT SUNLIGHT AND SEVERE
TEMPERATURE FLUCTUATIONS. FOR EXAMPLE, IF THE BINOCULAR
HAS BEEN USED UNDER VERY COLD CONDITIONS, BRINGING IT
INTO A HEATED ENVIRONMENT COULD CAUSE CONDENSATION
BUILD UP. ALLOW TIME FOR GRADUAL CHANGE IN TEMPERATURE.

HOW TO USE
First, adjust the width (interpupillary distance) of your binoculars so that
when you look through them, you see a single circular image. Then focus
the binocular for one eye at a time by turning the oculars (eyepieces)
until you see an equally sharp image with each eye. If more than one
person will be using the binoculars, you should mark the left and right
eyepieces for your own vision to permit quick readjustment.

USING THE COMPASS
The compass is a precision unit. It has
extremely fast damping so that there is almost
no ‘swing’ and is corrected for dip (Latitude).
The compass scale is in one degree increments
and is aligned with the vertical range finding
scale. When using the compass, always keep
in mind the local variation between magnetic
and true north.

The BUSHNELL TACTICAL binocular is designed for the military/law
enforcement field, but is also ideal for any demanding environment or
application where rock-solid durability is required. Featuring a liquid-filled
compass built into the viewing optics (model 280750), compass swing stops
immediately due to an advanced damping design. Bearings are called out in
easy-to-read precise 1° increments, ideal for navigation and locating objects
accurately. A range-finding scale allows the viewer to estimate the range to
objects of a known size. The BUSHNELL TACTICAL is fully waterproof/
fogproof and shock protected with suregrip rubber armoring, and has roll-
down eyecups for use with sunglasses and prescription eyeglasses. The
optics feature fully multi-coated lenses for excellent light transmission. The
BUSHNELL TACTICAL comes complete with rugged nylon case and neck
strap. Built to last, it includes a lifetime limited warranty.

USING THE COMPASS ILLUMINATOR
The BUSHNELL TACTICAL compass model
(#280750) comes with a built-in LED compass
illuminator for use at night and in low light
conditions. The compass housing is located on the
top right side of the binocular, with the two battery
compartments (inc. one for a spare set) found on
the front of the binocular, below the center hinge
shaft. When the ambient light does not permit you
to see the compass heading clearly, press the green power button on
the top compass housing. If the light is dim or does not come on, replace
the batteries. If the light does not operate after replacing the batteries,
please contact the Bushnell dealer nearest you.

HOW TO CHANGE THE BATTERIES
To change the batteries, use a thin coin to
remove the battery compartment cover by
turning it counter-clockwise. Remove the
two batteries. The batteries have a (+) on
the front and a (-) on the back. Be sure to
insert the new batteries with (+) signs in the
same direction. Replace the battery cover
by turning it clockwise. The two batteries
should be replaced at the same time. The batteries should be taken out
if the binoculars will not be used for a long time. Batteries left in the
binocular for prolonged periods of time without being used may leak and
cause damage to the binocular.
