General care recommendations
Follow the following care recommendations to ensure
maximum enjoyment and excellent viewing for many
years with your MINOX binoculars.
Binocular case included in scope of delivery
To protect your binoculars when not in use or when
traveling we recommend that you keep them in the
provided neoprene case.
Cleaning your binoculars
Keep your binoculars clean and dry. Avoid exposure
to excessive heat. Remove dust and foreign particles
from the body using a soft damp cloth. If you are using
your binoculars at sea or near salt water we strongly
recommend rinsing them off with fresh water after
use. Over time, sea salt can damage the objective
lenses and the optical quality of your binoculars.
Cleaning the objective lenses
and eyepiece lenses
Contamination such as dust, foreign particles and
grease from fingerprints impairs the imaging quality
(sharpness and contrast) of your MINOX binoculars.
Remove minor soiling and particles on the lenses us-
ing a soft brush. More severe soiling or fingerprints
on the lens surfaces can be removed using and optical
lens cloth and lens cleaner solution. We recommend
the MINOX Optical Cleaning Kit (order number 69731)
for cleaning your binoculars. Other suitable optical
cleaning solutions can also be purchased from spe-
cialist dealers.
Serial number
On the bottom of every pair of MINOX binoculars you
will find the “individual“ serial number. It is important
to make a record of this number and keep it in a safe
place in case of any loss.
In the illustration (Fig. 3) the arrow in the middle
indicates the boat’s direction of travel, in this case
roughly due south. When you look through your
binoculars the compass shows the observed buoy at
190°. The difference between South (180°) and the
observed buoy (190°) is 190° - 180° = 10°. This is
your first reference value for position determination.
To complete the determination of your exact position
you need a second reference value. In the following
illustration (Fig. 4) the indicated and observed light-
house is at 120° (300° - 120°) from the boat. You can
now determine your boat’s exact position on the map
by superimposing the two course lines. Your boat’s
position is exactly where the two lines cross.
Note:
Do not cover the light opening for the com-
pass (5) with your fingers, as you with otherwise
not be able to read the bearings.
Compass illuminator switch
The compass of your MINOX BN 7x50 C II has an illu-
minator switch so that you can also read the compass
in the dark. When you press the switch the compass
display has a backlight in red. There is no illumination
when the switch is not pressed.
