Adjusting the eye relief
The distance between the eyes differs between individuals.
To achieve optimal centering of the eye and eyepiece axis look through the
binoculars and change the angle of the center axis by folding or expanding
until you have a clear field of view.
Adjusting the focus
Your binoculars have single eyepiece adjustment (1) means. To focus look at an
object approximately 100 meters away. Close only your left eye and keep
turning the right eyepiece setting ring 1 until the object looked at is in
sharp focus. Then close only your right eye and turn the left eyepiece setting
1 until the object you are looking at is again in sharp focus. The binoculars
are now precisely adjusted to your eyesight. The single eyepiece setting (1)
is designed to give you a better perspective. When switching between objects
of varying distance the focus needs only be readjusted if the change in
distance is really major.
Reversing the eye-piece cup (3)
Note for spectacles wearers. The rubber eyepiece cups (2) are reversed when
using spectacles to look through the binoculars. The maximum field of view of
the binoculars can thus be exploited to the full.
Compass (3)
Your binoculars are equipped with a compass. If you look through them you will
see a scale in degrees (0 – 360) at the lower edge of your field of view. If
360 is exactly at the center of the scale you are looking directly to the
north (if 180, to the south).
Compass lighting
In the darkness, you can turn on the compass lighting by lightly depressing
the On/Off button (5). The lighting stays on as long as the button is
depressed.
Changing the batteries (Fig. 2)
Remove the plastic battery compartment cover (4) by raising it gently. Open
the compartment (4) by turning the latch with a coin and then change the
batteries (GP 186). Both batteries must have the positive (+) pole at the top
when inserted in the compartment.
Using the reticule (8)
Distance calculation
To determine the distance of an object you must first know its size. Look at
it and measure the image height on the reticule. In illustration (8) a 12 m
high building reaches 3.9 on the scale. Now turn the scale ring until the
white triangle (A) points to 3.9 on the upper scale. The lower scale on the
ring is the object size. In this example, the number 12 (B) stands for the
known height of the tower and is exactly below the number 300 (C) on the
distance scale. The tower is hence 300 m from you.
Determining size
You must know the distance it is away from you before you can determine the
size of an object. In this example, you‘re 400 m from the object. Look at it
and measure the image height on the reticule.
In illustration (8) a 12 m high building reaches 3.9 on the vertical scale.
Now turn the scale ring until the white triangle (A) points to 3.9 on the
upper scale. Over 400 (D) on the distance scale is the number 16 (E) on the
object size scale. The building height is therefore 16 m.
Cleaning your binoculars
- Remove coarse dust with a brush.
- Please use a soft fluff-free cloth for further cleaning.
- Should there still be residue on the lens dampen the cloth with standard cleaning fluid for optical glass (available from photography shops). Do not press hard when cleaning.
DISPOSAL
Dispose of the packaging materials properly, according to their types, such as
paper or cardboard. Contact your local waste disposal service or environmental
authority for information on the proper disposal.
In accordance with the regulations concerning batteries and rechargeable batteries, disposing of them in normal household waste is explicitly forbidden. Please pay attention to disposal of your used batteries as required by law – at a local collection point or in the retail market (disposal in domestic waste violates the Battery Directive). Batteries that contain toxins are marked with a sign and a chemical symbol. „ Cd“ = cadmium, „Hg“ = mercury, „Pb“ = lead.
- battery contains cadmium
- battery contains mercury
