Use With And Without Glasses; Focusing - Leica APO-TELEVID 65 Instrucciones

USE WITH AND WITHOUT GLASSES

Users who do not wear glasses should turn (see below)
the eyepiece cup to the left (anticlockwise) until it clicks
into place. This position secures the correct distance
between eyepiece and eye and prevents annoying stray
light. The click-stop provides the eye with a steady rest
and thus avoids blurring. When viewing with glasses,
the eyepiece cup should remain screwed in, so that the
entire field of view is visible.

FOCUSING

The dual focusing roller of the Leica Apo-Televid models
is equipped with two different ratios. The rear section
of the focusing roller (in viewing direction, 4b) is used
for rough or presetting; the front, narrower section (4a)
is used for fine adjustment. This ensures fast, precise
focusing at both low and high magnifications.
Note: The rear focusing roller can only be turned
between its two stops. Unlike this, the front roller is
equipped with a friction clutch, allowing it to be turned
beyond its stops. This is a matter of design, it neither
impairs focusing in any way, nor does it cause any
damage.
