Levenhuk Bino Ultra 6x18 [2/32] Diopter setting and central focusing

Diopter setting and central focusing

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.

• Adjust the diopter scale on the right eyepiece to "0".

Look through the binoculars at an object about 50

meters away.

• Shut the right barrel of the binoculars from the front

end and turn the central focusing wheel (B) until you

get the sharp image in the left eyepiece.

• Keep both eyes open during this procedure.

• Now shut the left barrel and turn the right eyepiece

until the image becomes sharp again.

WARNING:

Never look through your binoculars or with the unaided eye at the

Sun! It can result in permanent eye damage or even blindness.
