SET THE TWIST UP RUBBER EYECUPS
Twist the Rubber Eyecups up if you do not wear eyeglasses and
twist them down if you do wear eyeglasses to obtain the maximum
field of view.
HINT: Eyeglasses worn for nearsightedness should be worn when using binoculars, as you
may not be able to reach a sharp focus at infinity without them.
ADJUSTING THE INTERPUPILLARY DISTANCE (IPD)
Since the distance between the eyes (specifically, the distance
between the centers of the pupils) varies among individuals, the two
eyepieces of the binoculars must be correctly aligned (adjusted).
This is called adjusting the interpupillary distance. To adjust this
distance, lift the binoculars up to your eyes (using both hands)
and look through them at an object in the distance. Move the two
halves of the binoculars about the hinge until you see one clear
circle of image through both eyes.
SETTING THE DIOPTER COMPENSATION
This binocular has a diopter compensation adjustment setting
marked with +/- below the right eyepiece. This is the diopter
compensation adjustment dial (often simply called the “diopter”)
for the binocular and is used to adjust for any differences between
your eyes.
Whenever you first begin using a new binocular, of if you resume
using a binocular after someone else has been using it, the diopter
compensation adjustment dial should be re-set to ensure that you
are receiving the optimal level of optical performance from the
binocular for you own visual acuity. Once set, it will not need to
be set again unless it is changed by another user, or if the diopter
compensation adjustment dial has been unintentionally turned out
of its set position.
To set the diopter compensation adjustment for a binocular:
1. Set the dial at the zero point by placing the index mark on the
focusing eyepiece opposite the zero or middle on the scale.
2. Use one of the binocular’s objective lens covers to cover the
right objective lens.
3. Select a distant stationary object such as a tree or sign as your
focusing target. Keeping both eyes open, raise the binocular
to your eyes and center the selected focusing target into the
binocular’s field of view.
4. Still keeping both eyes open while viewing the target, use the
center focus dial to bring the target into sharp focus in the left
eyepiece. Once this is done, do not adjust the center focus dial
again until the end of this process.
5. Lower the binocular and move the objective lens cover to cover
the left objective lens.
6. Still keeping both eyes open, relocate and view the focusing
target. This time, use the diopter compensation adjustment dial
to bring the target into sharp focus in the right eyepiece.
7. Lower the binocular and uncover the left eyepiece. You should
now be able to view through both eyepieces and adjust
focus using the center focus dial with the proper amount of
compensation maintained between your two eyes.
If the diopter compensation adjustment dial ever becomes
moved – either intentionally or unintentionally – simply repeat this
process to re-set it.
Now you are ready to use your binoculars — enjoy the view!
