WARNING:

Never look through your binoculars or with the unaided eye at the Sun! It can

How to adjust interpupillary distance

The distance between the eyes is called "interpupillary distance". It varies from

person to person. To achieve perfect alignment of lens to your eyes, follow

these simple steps:
• Hold your binoculars in the normal viewing position.

• Grasp each barrel firmly. Move the barrels closer together or further apart

until you see a single circular field. Always reset your binoculars to this

position before using. Most binoculars have a graduated area at the top of

the centre hinge for reference in subsequent use in setting interpupillary

distance.

How to adjust the magnification

Set the maximum magnification by turning the zoom lever (D).

Note: with variable magnifications you should first align the binoculars at the

maximum magnification. If you have adjusted focus at small magnification, the

image sharpness can be lost when you increase the magnification.

focusing wheel (B) until you get the sharp

image in the left eyepiece.

procedure.

right eyepiece until the image becomes
