Adjustment of focusing
By turning the focusing
wheel you can focus any
object sharply at a distance
of 2 m/6.6 ft to infinity.
In the infinity position the
little nose of the focusing
wheel is at the top.
Dioptric compensation
To achieve optimal image quality, the possibly
varying visual acuity between the left and right eye
must be corrected.
Use without eyeglasses and equal acuity of both eyes, or
with eyeglasses:
1. Pull the focusing wheel outwards.
2. By turning the focusing wheel, set the dioptric
scale to "0".
3. Push the focusing wheel back in.

Maintenance and Care
Lens-cleaning cloth
You can clean high sensitive lens surfaces with
the enclosed special cloth made of micro-fibres.
It is suitable for objective lens, ocular lens and
eye-glasses.
Please keep the cloth clean, as dirt can damage
the lens surface. If the cloth gets dirty, it can be
washed in luke-warm soapy water and air-dried.
Please use it exclusively for cleaning lens sur-
faces!
