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 adjust-
ment 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-
clockwise), 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.
