2.8 ADJUSTING THE INTERPUPILLARY DISTANCE
To see a single round image, turn both ocular fins toward the
outside until your eyes adjust to the optimum distance.
2.9 DIOPTER ADJUSTMENT
To achieve optimal image quality, the possibly varying visual acuity between the left
and right eye must be corrected.
Use with equal acuity of both eyes:
The diopter adjustment is set to "zero".

Use with varying acuity of both eyes:
1. Use the left eye to look through the left eyepiece and
use the focusing adjustment ring to focus on the selected
object.
2. Now, using your right eye, look at the same object
through the right eyepiece and use the diopter adjustment
to set the optimal image sharpness. Keep the other eye
closed.
2.10 FOCUSING
• For distant objects, turn the focusing adjustment ring to the
right (clockwise).
• By turning the focusing adjustment ring to the left (anti-clock-
wise), you can observe objects that are nearer.
• In order to ensure fatigue-free observation, turn the adjust-
ment ring for focusing a bit to the left (anti-clockwise) until the
image becomes slightly unsharp. Then turn the adjustment ring to the right (clockwise)
until the maximum image definition is attained for the first time.
