cuitry for automatic iris control, as well
s a neutral-density spot filter. The lens
provides optimum viewing contrast re-
gardless of light conditions or brightness
variations within the scene.
This lens is powered with 8.516 VDC
power from the camera.
2. INSTALLATION
NOTE: The front element of a zoom
lens moves in and out as the lens focus is
changed. The closest focusing position
corresponds to the greatest extension of

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 maxi-
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.

lighting to open the iris up to its maxi-
mum. This is necessary to obtain the
most accurate back focus adjustment.
2.4 Autoiris Adjustment
Autoiris (AC) zoom lenses must be ad-
justed for optimum picture quality. Al-
though the automatic light control (ALC)
adjustment is provided on the lens, the
level control is preset at the factory and
should not be readjusted unless other
methods of optimizing the picture are
unsuccessful.
Before making any attempt to adjust the
lens, perform the following monitor
setup procedure: turn the BRIGHTNESS
and CONTRAST controls on the monitor
fully counterclockwise, then turn them
back to approximately midscale. These
controls vary from monitor to monitor,
but these settings are adequate for initial
adjustment.
2.4.1 Automatic Light Control (ALC)
This control adjusts the contrast level of
the picture. The limits of the adjustment
are labeled P (peak) and A (average), and
the control is set at average at the factory.
When making an adjustment, turn the
potentiometer a little at a time. If the
contrast is too strong, turn the potenti-
ometer clockwise, toward P; if the con-
trast is too weak, turn the potentiometer
counterclockwise, toward A.
2.4.2 Video Level (LEVEL)
The level control is preset at the factory
for optimum performance, so normally
no adjustment is required. Adjusting this
control when it is not necessary may spoil
the picture quality. If all other adjust-
ments fail to produce a satisfactory pic-
ture, adjust the LEVEL potentiometer.
The adjustment limits are low (L) and
high (H).
