7. ABOUT THE LENSES
7.1. Lens (optional) Selection and Camera Setting
●When using the flickering-reduction function outdoors or under the fluorescent lighting in the area with the
power frequency of 50 Hz, use the auto-iris lens. Follow the procedure below to perform the setting:
1. Set the Lens Auto/Manual selector switch of the mode switch ⑥to "AUTO" position (factory-preset
position).
2. Set the lens selector switch ⑤to "DC" or "VIDEO" position depending on the type of auto-iris lens to use.
Factory-preset for "DC" position.
3. To reduce flickering, set the flickering-reduction switch of the mode switch to "1/120" position . Factory-
preset for "(1/50)" position.
●When using the flickering-reduction function indoors or in locations where the lighting condition does not
much change, you can use the manual or fixed iris lens by making the following camera settings:
1. Set the Lens Auto/Manual selector switch of the mode switch ⑥to "MANU" position. Factory-preset for
"AUTO" position.
2. Set the flickering-reduction switch of the mode switch to "(1/50)" position. Factory-preset for "(1/50)"
position.
Notes
●When the flickering-reduction switch is set to "1/120" position, the automatic
sensitivity adjustment function cannot be used even if the Lens Auto/Manual
selector switch of the mode switch is set to "MANU" position. Use the auto-iris
lens.
●To avoid damaging the internal sections of the camera's lens mount, be sure
that the lens flange is less than 5 mm thick as illustrated on the right.
●C-mount lenses must be used in conjunction with the Lens Mounting Adapter
CF-5 (optional).
7.2. Auto-Iris Lens Installation
1. Attach the lens to the camera.
2. Insert the connector from the lens into the lens
connector ③.

8. ADJUSTMENT
1. Supply power to the camera. The power indicator ⑪will light.
2. Flickering of lighting may interfere with the view when the camera is used in the room in the area with
power frequency of 60 Hz. To view the flickering-free picture, shift the flickering-reduction switch of the
mode switch ⑥to "1/120" position.
Note
Placing the flickering-reduction switch in the "1/120" position makes the sensitivity lower than in the "(1/50)"
position. Use the "(1/50)" position when the flickering does not interfere with the view or when the camera
is used in dark locations.
3. Connect the video output terminal ⑩to the monitor so that the picture may be displayed on the monitor.
4. Adjust the camera angle viewing the monitor screen.
5. Adjust the lens for the best possible picture reproduction.
●When using the DC input type lens, adjust the sensitivity with the iris control ⑦.
●When using the VIDEO input type lens, adjust the sensitivity with the ALC or LEVEL control of the lens.
Notes
●Because the iris control is set to the optimum position by the factory, avoid handling it. Rotating the
control more than required could downgrade the image quality or result in camera malfunction. When
readjusting the camera, first set the AGC switch of the mode switch to "OFF" position, then adjust the
iris control for the best possible picture reproduction. After adjustment completion, cover the lens front
with the hand and remove it from the lens a few seconds later. If you find the lens iris is functioning
correctly, shift the AGC switch back to "(AGC)" position.
●The object that was brought into focus in bright locations could be out of focus in dark conditions. In
such cases, use a commercial ND filter for focus adjustment.
●When the distance to an object is shorter than the lens' shortest focusing distance or when a zoom lens
is used, if the object is out of focus, adjust the camera as instructed below (back focal length
adjustment):
5-1. Attach a lens to the camera.
5-2. Loosen the back focal length
adjustment ring fixing screw ①.
5-3. Rotating the back focal length
adjustment ring ②, adjust it to the
optimum position.
5-4. Retighten the back focal length
adjustment ring fixing screw.
6. Set the synchronizing method using the synchronization selector switch of the mode switch ⑥.
One of the following methods can be selected: internal locking (switch position: "INT"), line locking ("LL"
position), and vertical signal external locking ("INT" position). In this setting, when the camera is connected
to other equipment capable of using vertical signal external locking, the method is automatically switched
from internal locking to vertical signal external locking. When using the line locking method, set the
synchronization switch to "LL" position.
Note
You cannot use the line locking method in the area where the power frequency is 60 Hz.
7. Using the vertical phase control ⑧, synchronize the camera. (This adjustment is required only for line
locking mode.) When using multiple line-locked cameras ("LL" position) and switching camera outputs by
means of a sequential switcher, the pictures may be distorted depending on the distance to the power
source or camera installation conditions. In such cases, turn the vertical phase control to avoid the picture
distortion.

image reduction than to a sensitivity level increase.
Normally, use this mode.
Use this mode to automatically adjust a AGC level without
using the sensitivity increasing function, and create
pictures free from residual images in poor lighting
conditions.
The AGC level is always maintained at a set level of 0-18
dB, and a sensitivity level automatically increases to up to
the level of the designated incremental parameter as the
lighting condition worsens. Use this function when noise is
a greater annoyance than a residual image.

●Lens auto/manual selector switch
AUTO MANU
Set the switch to this position
when using an auto-iris lens.
AUTO MANU
Set the switch to this position
when using a manual-iris or
fixed iris lens.
●AGC switch
OFF (AGC)
Normally, set the switch to this
position. Even when an ambient
brightness level changes, a video
output level is automatically
maintained constant, providing
the clear picture.
OFF (AGC)
Set this switch to OFF position
when the brightness level of an
object frequently changes.
●Backlight compensation switch
OFF (BLC)
Normally, set the switch to this
position.
OFF (BLC)
This position prevents an object
from becoming too dark and the
picture background from
becoming too white to be
viewed.
10. ABOUT THE MODE SWITCH
Set each switch to the position that provides the best picture reproduction. The color camera has the remote
camera control function. When setting the camera's property with the menu key, set the corresponding switch
(AGC, backlight compensation, ATW, and flickering reduction) to the "(MENU)" side (right-hand side).

●ATW switch
AWB (ATW)
Normally, set the switch to this
position. This position permits
the camera to automatically
adjust the white balance
depending on the type of light
source (change in color
temperature).
When the ATW function is disabled
because the camera is used under a
special light source or multiple light
sources that differ in color
temperature, set the switch to AWB
position. As soon as the switch is
shifted to this position, the camera
automatically adjusts the white balance of the on-screen
image and thereafter, keeps the white balance status.
Since several seconds are required before the white
balance is set, observe that the object does not change
during that period. When readjusting the white balance, first
shift the switch to "(ATW)" position and shift it back to AWB
position, then adjust the balance in the same manner.

1/120 (1/50)
Normally, set the switch to this
position. Flickering of the picture may interfere with the view under
fluorescent lamps in the area
with power frequency of 50 Hz.
In such cases, set the switch to
"1/120" position, and the image
free from flickering can be
obtained.
Note
Placing the flickering-reduction switch in the "1/120"
position makes the sensitivity lower than in the
"(1/50)" position. Use the "(1/50)" position when the
flickering does not interfere with the view or when
the camera is used in dark locations.
●Synchronization switch
INT LL
Set the switch to this position
when a single camera is used
and it does not need to be
synchronized with other camera.
INT LL
Set the switch to this position
when locking multiple cameras
to the power frequency.
Note
The line locking system cannot
be used in areas where the
power frequency is 60 Hz.
