Adjustments Ideal for people wearing glasses
To ensure that people wearing glasses also have an optimal
field of view MINOX binoculars are fitted with rotating
eyecups.
For use without wearing glasses
Those who do not wear glasses must turn the eyecups at
both eyepieces in counterclockwise direction until they
engage in the extended position. The binoculars are now
set at the correct distance to the eyes.
For use with glasses
Those who wear glasses must leave the rotating eyecups on
both eyepieces in the original position (as delivered) or, if
necessary, turn the eyecups in clockwise direction until they
noticeably engage. In this setting you can enjoy the entire
field of view without disturbing interference at the edges.
The right distance between the eyes
(inter-pupillary distance)
Look into the eyepieces of your binoculars and adjust the
angle of the hinged tubes until you have a singular circular
viewing field from both fields of view.

Focusing For pin-sharp definition you must adjust the optics of the
binoculars to your individual eye vision. To do this, please
proceed as follows:
(a) First get a far-off, fixed object into view. With closed right
eye turn the central focusing until the object in view has
optimal sharpness for your left eye.
(b) Next you must get the same object in view again with
your left eye closed and turn the adjusting ring on the right
eyepiece until the object has optimal sharpness for your
right eye.
(c) Your MINOX binoculars are now set to the individual
vision of both eyes.
(d) For the observation of different objects at varying
distances you will always have to adjust the focusing. To do
this, please now just use the central focusing.
Caution:
Do not use binoculars to look into the sun, this could lead
to eye injuries.

Attaching a tripod
Tips on how to care
For shake-free viewing we recommend the use of a tripod,
especially for high-power magnification. For this purpose,
use the MINOX tripod adapter which is available as an
optional accessory (Order no. 69727). Remove the cover
screw (6) on the bottom of the binoculars and attach the
MINOX tripod adapter in its place. Keep the cover screw
(6) in a safe place and replace it after removing the tripod
adapter.
Soiling impairs the brightness of your MINOX binoculars.
We therefore recommend always removing fingerprints,
dust and other forms of soiling on the surfaces of the lens
and eyepieces using a soft hair brush or the special MINOX
Lens-Cleaner (Order number 99605).
On the bottom of each pair of binoculars you will find the
factory number. It is important that you make a note of this
number for the event of loss.
