Changing the batteries (Fig. 2)
Remove the plastic battery compartment cover
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
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 a 12 m high building reaches to
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
. The lighting stays on as
by
GB/IR
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 a 12 m high building reaches to 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

2. Please use a soft fluff-free cloth for further cleaning.
3. Should there still be residue on the lens dampen the
cloth with standard cleaning fluid for optical glass

when cleaning.
