Setting the pupillary distance
Fold the two eyepiece tubes (1) together or unfold them until you see a single
circular image when looking through both eyepieces. Your binoculars are now
correctly adjusted for your pupillary distance.
Focusing
If you do not normally wear eyeglasses, you will see distant objects sharply if
the dioptric adjustment (3) is set to 0. For closer ranges, this setting must be
changed by turning the knurled center focusing wheel (2).
If the degree of shortsightedness or farsightedness is the same in both of your
eyes, either deficiency can be compensated for by turning the center wheel.
If your eyes have different visual acuities and if you do not wear eyeglasses,
proceed as follows for focusing:
1. Look through the binoculars with both eyes and cover objective of the
right-hand barrel with your hand. Focus the binoculars for your left eye
by turning the center wheel (2).
2. Cover left-hand barrel with your hand and turn the diopter scale for the
right eye without changing the setting of the center wheel until the same
target is in focus. The setting in which the image is just sharp and no
more is that in which your eye muscles are relaxed.
The different refractive powers of your eyes have now been compensated –
you can see sharply and clearly with both eyes.
If you wear your eyeglasses when looking through the 20x60 S, the above
procedure is not needed, as the eyeglasses correct these deficiencies including
astigmatism.
The center focusing wheel is used to adjust the binoculars to varying
distances.
