Adjustment of the distance

between the eyepieces

The distance between the eyes is different

from person to person . In order to achieve

an optimum visual field, the distance be

-

tween the eyepieces must be set individ-

ually . For this purpose, the two halves of

the binoculars are pushed together or

extended around the centre axis until one

collective, circular image without shadows

is shown from the images of both lenses .

Adjustment of the eyecups

For setting the correct distance of the

eyes to the ocular lenses, the binoculars

of the Blaser Primus series feature eye-

cups .

Use without glasses

For the use without glasses, the eyecups

of both eyepieces are unscrewed to the

left (counter-clockwise). Three different

latching graduations provide the constant

adjustment of the correct distance from

the eyes to the eyepiece lenses .

Use with glasses

Wearers of glasses turn the eyecups of

both eyepiece lenses in up to the stop

(delivery condition) . This setting enables a

view across the entire field of vision with

-

out being “cut off” at the edge.

Adjustment of the binoculars

Adjustment of the focus

By turning the focusing wheel [3], every

object can be set from the minimum

focusing distance (approx. 2 m) to being

focused to infinity.

Dioptre compensation

Since the eyes of many people supply

various eyesight values, this difference

can be compensated for by means of the

dioptre adjustment ring [2] .

Adjustment for an identical vision on

both eyes

Turn the dioptre adjustment ring to zero

position .

Adjustment for varying visual acuity

between both eyes

When looking at a more distant object

(approx. 100 m) through the binoculars,

set the focus correctly for the left eye

using the focusing wheel [3], keeping

the right eye closed . Then set the correct

focus for the right eye using the dioptre

adjustment ring [2], keeping the left eye

closed .

DANGER:

Never look at the sun through the bin-

oculars, as doing so can cause serious

injuries to the eye .

Maintenance tips

Smudges on the lenses may impair the

sharpness of your Blaser binoculars . We

therefore recommend removing finger

prints, dust and other impurities of the

lens and eyepiece surfaces using a soft

hair pencil and/or the lens cloth supplied .

The housing of the binoculars can be

cleaned with a damp cloth . Please use

the optical cleaning cloth supplied exclu-

sively for cleaning the lenses .
