instructions below.
1.
View an object in the distance through the
binocular.
2. Cover the right objective lens with your hand
or the objective lens cap.

. Viewing the same object, rotate the right
eyepiece (the diopter) until the image viewed
with your right eye is clear and sharp.
6. Your binocular is now adjusted to your eyes
and focusing on any object can now be
achieved by simply turning the focus wheel.
TIp: Eyeglasses worn for nearsightedness should be worn when using
binoculars as you may not be able to obtain focus at infinity
without them.
eyecup adjustment
The Cometron binoculars feature foldable
rubber eyecups to accommodate both eyeglass
and non-eyeglass wearers. If you do not wear
eyeglasses, leave the rubber eyecups in the
up position. If you wear eyeglasses, make sure
that the eyecups are folded down to obtain the
maximum field of view. When done observing,
make sure the rubber eyecups are in the up
position for storage.
