USING YOUR FUTURUS™ 8-24x50 ZOOM BINOCULAR

Before using your binoculars for the first time, please review all of the instructions contained within the
instruction manual. Carefully following the instructions, you will get the most out of this precision
instrument. Protect your binoculars by exercising caution when in the company of children or people
unfamiliar with the proper use of optical instruments.

Attention!
Always protect your eyes and never look directly at the sun or any other source of bright light
through the binoculars!

Setting the interpupillary distance (IPD)

Attention!
When setting the Interpupillary Distance, be careful not to jam the tips of your fingers in the folding
action of the two barrels of the binoculars.

• Remove the binoculars from their case and flip open all four lens caps on both the large objective (1)

and the smaller eyepiece lenses (2).

• For utmost utility, the objective lens caps (1) are constructed to lie flat against the housing. For your

convenience, you can rotate the opened lens caps to about their center until you find the most
unobtrusive position.

• Pick a group of objects off in the distance and folding or unfolding the binoculars (moving the two

halves of the binoculars up or down close to the central pivot) while observing through the eyepieces,
choose such a position when you see only one image of the objects and feel they are equally remote.

FOCUSING THE BINOCULAR AND DIOPTRIC ADJUSTMENT

• Aiming the binoculars at any distant object, turn the large center focus wheel (3), until you see a sharp

image through the left fixed eyepiece. Do not attempt to rotate the left eyepiece!

• With the image in the left eyepiece now focused, you can proceed to Dioptric Adjustment. This will

address the natural differences between the right and the left eyes and reduce eyestrain from
prolonged use.

• Look through the right eyepiece at the distant object and turn the Diopter Knob of the right eyepiece

(4) until you get a crisp image.

• Turn the central focusing wheel (3) until you get a sharp image through both barrels.

• As you continue viewing, you may find that you need to refocus the image. This should be done only

using the central focusing wheel (3) as you have already tuned the binoculars to your individual needs.

• Special characters “+ | -“ and “Δ”, located near the right eyepiece (4), will help you to easily mark

and remember your personal setting for the Diopter Knob.

MAGNIFICATION ADJUSTMENT

The Futurus Zoom Binoculars have a magnification change feature – from 8x till 24x. In order to adjust the
desired magnification, using the adjustment knob (5) set the mark opposite the respective magnification value
shown on the numeric scale located on the underside of the right eyepiece (see picture).

NOTE:

Due to the magnification changing, the scale of the image also changes, so to make operation most
comfortable, it is advisable to re-focus using the central focusing knob (3).
