CARE
• When cleaning optical lenses, use included lens cloth or other
soft, lint-free cloth. Remove any visible dust or debris by blowing
or using a lens brush.
• To remove smudges or prints, rub gently in a circular motion with
a lens cloth or other soft cotton cloth. Coarse fabric can scratch
your lenses.
• If further cleaning is required, use lens cleaner or diluted
isopropyl alcohol to remove dirt and smudges - other chemicals
may damage your equipment. Always apply solution to a lens
cloth first, never directly to the lens.
• Store binoculars in a moisture-free area. Be sure to dry your
equipment before packing it up.
• Always use lens caps when binoculars are not in use.
• Always store your binoculars in a protective case to avoid
accidental damage.

• Never look at the sun through your binoculars. Doing so can
cause permanent damage to your eyes, including blindness.

stored.
• While viewing objects at distance, be sure to be aware of
what’s going on around you to prevent harm to yourself and
your binoculars.

To get the most from your Zhumell marine binoculars, be sure to understand
and properly use these features. Doing so will lead to the most satisfying
experience possible from your new optical equipment.
INTERPUPILLARY DISTANCE
Interpupillary distance is the distance between the eyepieces of a binocular.
Easy adjustment will ensure that your binoculars are giving you the view you
want. To adjust interpupillary distance, follow these simple steps:
1. Hold binoculars in the normal viewing position
2. Grasp each barrel firmly
3. Gently move the barrels closer together or farther apart until you see a
single circular field
4. When you view appears as a single circle, the interpupillary distance is
correct. Note the settings for easy adjustment in the future.
USING YOUR
ZHUMELL MARINE BINOCULARS
EYEPIECE FOCUS
Your Zhumell binoculars have individual eyepiece focus, which allows for
greater control over your view. Each eyepiece is focused using the diopter ring
directly behind the lens. To bring your binoculars into focus, follow these steps:
1. Choose a distant object on which to focus
2. Close your left eye or cover the left objective lens and turn the right diopter
until the object is in perfect focus
3. Close your right eye or cover the right objective lens and turn the left
diopter until the object is in perfect focus
4. When viewing with both eyes, the object should now be crystal-clear. If it is
not, make individual adjustments as needed.

USING YOUR
ZHUMELL MARINE BINOCULARS
INTERNAL RETICLE AND COMPASS ILLUMINATION
To illuminate the internal compass and reticle for low-light viewng, just
press and hold the power button top of the binocular. Illumination will turn
off when the button is released.
BATTERY REPLACEMENT
To replace the batteries that power the compass and reticle illumination,
remove the battery housing cover using a coin. Place two (2) batteries,
type SR-44, in the chamber with the negative side toward the binocular
body, and replace the battery housing cover.
USING THE RETICLE AND COMPASS
The Zhumell marine binoculars use degree measurements to determine
your position, which are read as follows:
North = 360, East = 90, South = 180, West = 270.
• Distance - If the height of a viewed object is known, use the following
equation substituting the object height for variable H: L = H/MILS x 1000
• Angle - To calculate the included angle of a viewed object, use the
following equation: x = 0.06 x MILS
• Height - If the distance to a viewed object is known, use the following equation
substituting the object distance for variable L: H = L x MILS/1000
