SETTING THE DIOPTER ADJUSTMENT
The diopter adjustment (4) of the binoculars is important to provide a sharp image and avoid eye strain.
Readjusting the diopter adjustment is not necessary if the binoculars are operated by only one user.
To set the diopter adjustment:
1) Look through the left eyepiece with the left eye at a distant object.
2) Rotate the focus ring (3) until the object is in focus.
3) Look through the right eyepiece with the right eye at the same object.
4) Rotate the diopter adjustment until the same object is in focus
ADJUSTING THE INTERPUPILLARY DISTANCE
Interpupillary distance is the distance between your eye’s pupils. In order to obtain a single image, the center of the
binocular’s eyepieces (1) must be set the same distance apart as your eye’s pupils.
To set the interpupillary distance:
1) Look through the binoculars with both eyes.
2) Rotate the binoculars gradually until the two images become one.
FOCUSING ADJUSTMENT:
Focusing adjustment is necessary to view objects at different distances.
To adjust focusing:
1) Look through the binoculars with both eyes at a distant object.
2) Rotate the focus ring (3) until the image is crisp and sharp.
