illuminated from the rear (from the direction of
the stand column).

By pressing the rear button once briefly
(Fig. 18/1), the adjusted segment is turned
forward clockwise by one quarter turn in each
case.

By pressing and keeping the rear button
(Fig. 18/1) pressed for over 2 seconds, the
adjusted segment is set into continuous rotation
(rotation steps of 1/8 circle, 1 second per turn in
each case).
•
By pressing the rear button once more (Fig. 18/1), rotation is stopped and the specimen is backlit
again.
