MUST NOT be set for longer than
recommended distances or the lens
may be seriously damaged.
CAUTION: Do not mount an
ens on a camera which is installed
on a autopanning unit. Such use
will cause excessive wear, as the
iris mechanism constantly compen-
sates for
light levels.
2.1 Mounting the Lens
1. Screw the lens firmly into the
mount on the camera. Once the lens is
attached to the camera, the lens orien-
tation may be adjusted.

3. If the lens is not oriented correctly,
rotate it in either direction against the

position to be easily installed on a

2.3 Focusing and Adjusting Procedure
The following procedure should be used
to obtain the best results in setting optical
and mechanical focus.
1 . Adjust the zoom function to the
mum telephoto setting, then focus on
a convenient distant object. Readjust
the zoom to the maximum wide angle
setting and check the focus. The focus
should remain reasonably sharp. If it
does not, the back focus (mechanical
focus) of the camera must be adjusted
according to steps 2 and 3.
