OCEANA 7X50 BINOCULAR
MODEL # 71189-A
THANK YOU FOR PURCHASING A CELESTRON BINOCULAR. WE HOPE IT BRINGS YOU MANY YEARS
OF ENJOYMENT. TO MAXIMIZE YOUR SATISFACTION OF THE BINOCULAR, PLEASE READ THESE
INSTRUCTIONS ON USE AND CARE BEFORE USING IT.
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.
SET THE RUBBER EYECUPS
Keep the Rubber Eyecup up if you do not wear eyeglasses but fold
them down if you do wear eyeglasses to obtain the maximum field
of view
.
The batteries included with your binocular are for illuminating the
compass, so you can see it easily in the dark. You need to install the
batteries which are located in the case pocket. Unscrew the battery
cap by hand and then remove the screw with a coin or screwdriver. The
batteries are to be installed with the positive (+) side facing up towards
you. Replace the screw and battery cap. If you will not be using the
binocular for a long period of time (a few months or more), you should
take the batteries out to preserve their life.
ADJUSTING FOCUS
Since most people have a variance of vision from their left eye to their
right eye, you must adjust the focusing system. Use the following steps
to achieve focus: (1) Close your right eye and look through the left side
of the binoculars with your left eye at the subject matter. Rotate the
center focusing wheel until the image appears in sharp focus; (2) Close
your left eye and look through the right eyepiece (called the diopter).
Rotate the right eyepiece until the image appears in sharp focus;
(3) Look through both eyepieces with both eyes open. Since you’ve
already adjusted the right eyepiece, use only the center focusing wheel
to refocus on a new object at a different distance.
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.
