Eye distance
The distance between one's eyes varies
from person to person, so it is essential
that you adjust your binoculars before
you use them. Take the binoculars in both
hands (Fig. 1) and hold them to your eyes.
Fold them so that you see a single circle
when looking through them with both
eyes (Fig. 2).
Adjusting the focus
Find an object over ten metres away. Take
a look through the eyepieces with both
eyes (2) and turn the focusing wheel (Fig.
3, 1) until the object is in focus.

Notes on cleaning

• Clean the eyepieces and lenses only
with a soft, lint-free cloth like a mi-
crofibre cloth. To avoid scratching the
lenses, use only gentle pressure with
the cleaning cloth.
• To remove more stubborn dirt, moisten
the cleaning cloth with an eyeglass-
cleaning solution and wipe the lenses
gently.
