Video signal type lens adjustment

Adjustment is required after replacing the lens or
if using the camera for the first time.
1) Preparation
(1) Gain in the GAIN/SHT. manu is set to
PRESET, and PRESET under that is set to
+0dB.
(2) If the light source has a flicker component
(e.g., fluorescent or mercury lighting),
change the electronic shutter mode (GAIN/
SHT. menu Shutter or Variable) to reduce
the flicker.
(3) Adjust the white balance. (Page 22)
2) Adjustment
Hold the U button depressed and press Setup for
about 2 seconds to display the Special Set menu.
Change to the Lens screen and check the Lens
Type setting. If DC, change this to Video.
(4) Auto iris operates, but scene is dark. Even
if lens Level control is adjusted ， the
quadrangle mark to the left of the H mark is
moved.
Boost the gain.
GAIN to 1 － 12 dB in order to raise the
sensitivity.
Note: The video signal level indicator sensitivity is
high in order to increase lens adjustment
accuracy. Operate the lens Level control

Set GAIN/SHT. menu
(1) Set the lens ALC control fully toward the
average (Av ) position.
(2) If auto iris hunting occurs, reduce the Iris
Gain setting.
(3) Adjust the lens level control to where the
center quadrangle is positioned at the video
signal level indicator cross mark.
If the camera video signal detection level is
optimum，the quadrangle mark is center. If
larger than optimum， the quadrangle marker
to the right of H is moved and if lower，the
quadrangle mark to the left of L is moved.
3) Lens adjustment difficult or impossible
(1) Video signal level indication unstable
Unstable indication can occur if the light
source has ａ flicker component （ e. g.,
fluorescent or mercury lighting）, change the
electronic shutter mode (GAIN/SHT. menu
shutter or Variable ) to reduce the flicker.
(2) Lens Level control fully at Hi, but auto iris
inoperative Reduce the Iris Gain setting.
(3) Lens Level control fully at Low, but auto iris
inoperative Increase the Iris Gain setting.

Camera mounting

The camera is provided with threaded screw holes
at the top and bottom. These allow mounting to
either a tripod or a mounting bracket.
Screw type: U 1/4-20
Length: 4.5 to 6 mm
Screws longer than 6 mm can
cause internal damage, while
less than 5 mm prevents secure
fastening and risks dropping to
cause damage and injury.
