Instructions for Use
Your PROMASTER binocular is a precision instrument designed to provide
many years of pleasurable viewing. These instructions will help you achieve
optimum performance by explaining how you can adjust the binocular to your
eyes and how to care for this instrument. Read the instructions carefully before
using your binocular.
7. Using the “diopter setting” adjustment ring, focus the same object being
viewed. Caution should be used as over turning or forcing the diopter
eyepiece can cause damage or cause the eyepiece to break away from the
chassis.
8. Your binocular should be adjusted for your eyes. Focus at any far or near
distances can now be attained simply by turning the center focus wheel.
Make a note of the diopter setting for your eyes for future reference.
Instructions for Care
Your PROMASTER binocular will provide years of trouble-free service if it
receives the normal care you would give any fine optical instrument.
Non-waterproof models should not be exposed to excessive moisture.
Eye Adjustments (Figure 1)
How to adjust for distance between your eyes. The distance between the eyes,
called “interpupillary distance,” varies from person to person. To achieve perfect
alignment of lens to eye, follow these simple steps:
1. Hold your binocular in the normal viewing position.
2. Grasp each barrel firmly. Move the barrels closer together or further apart
until you see a single circular field. Always reset your binocular to this
position before using.
How to adjust for individual eye strength. As individual eyesight varies from
one person to another, all PROMASTER binoculars have a diopter setting
feature which allows you to fine tune the binocular to your vision. Follow the
focusing instructions below for your type of binocular.
Focusing
1. Adjust interpupillary distance. (Figure 1)
2. Set the “diopter setting” (Figure 2) to zero and view a distant object.
3. Keep both eyes open at all times.
4. Using a lens cover or your hand, cover the objective (front) lens of the
same side of the binocular that has the “diopter setting.” This is usually the
right side.
5. Using the center focus wheel, focus on a distant object with fine detail (e.g.,
brick wall, tree branches, etc.) until it appears as sharp as possible.
6. Uncover the objective lens on the diopter side, cover the other objective lens,
then view the same object.
1. If your binocular has roll-down, flexible eyecups, store it with the eyecups
up. This avoids excessive stress and wear on the eyecups in the down
position.
2. Avoid banging and dropping.
3. Store in a cool, dry place.
4. Looking directly at the sun with your binocular may be very harmful to your
eyes.
Cleaning
1. Blow away any dust or debris on the lens (or use a PROMASTER lens pen).
2. To remove dirt or finger prints, clean with a “microfiber” cleaning cloth like
the PROMASTER SoftClean or MicroClean soft cleaning cloth. Rub lightly in
a circular motion. Use of a coarse cloth or unnecessary rubbing may scratch
the lens surface and eventually cause permanent damage.
3. For a more thorough cleaning, photographic-type lens cleaning fluid like
PROMASTER OpticClean may be used. Always apply the fluid to the cleaning
cloth ~ never directly on the lens.
