Preparation for Demonstration • Prepare for your demonstration
1. Connect a optical fiber cable and ROP cable
• See Connection.
2. Check a camera power switch.
• Switch to CCU.
3. Initialize a ROP and CCU setting to factory setting.
• ROP:CALL + SW4 (ROP)
• CCU: Remove a panel and Menu ON. Maintenance – System – Initialize
4. Change Format (Default: 1080/60i)
• See format change. You have to change camera head, VF and CCU.
5. Check ROP setting.
• Light ON: ROP ON, Head ON, VF PW, IRIS ACTIVE, M-PED ACTIVE
• Light OFF: HEAD
6. Set a Range (Iris control range) to maximum.
7. Check a lens.
• Set Iris to A (Auto). Set Zoom to S (servo). To Top

Trouble Shooting: Operation
• Iris doesn’t work by joystick! – Check lens. Lens has manual and auto
iris mode. Set to A (Auto Iris), otherwise it doesn’t work.
– Check the Close button. If it lights on, it doesn’t work.
– Check the AUTO button of ROP. • If it on, it doesn’t work.
– Check IRIS ACTIVE button. • If it is off, it doesn’t work.
• Master pedestal doesn’t work by joystick. – Check the M-PED ACTIVE button.
• If it is off, it doesn’t work.
• ND and CC filter switching don’ work. – Check the head button. It must light off.

Trouble shooting: B/W screen (PM out)
• The monitor is B/W. 1. PM output is B/W.
– You have to select ENC to get color signal. If you choose R, G or B, it becomes B/W.
2. CCU output is B/W. • OPERATION– Setting3 – MONO SW
You should select OFF. Otherwise output becomes B/W.
3. The monitor mode is B/W. 1. Check the monitor mode.

Trouble shooting: Format change
1. NG appears when you change format. 1. You should meet the format each peripherals,
camera, VF, CCU.
In case of 1080i/59.94:
1. Camera: Hold MENU button
– Maintenance – Format – Format
59.94i,50i
Select 59.94i.
2. VF: Change format by physical switch.
– Switch to 1080i/60
3. CCU:Remove the front cover and Turn on menu.
– OPERATION– Setting1 – CCU mode
Select 1080/59.94i(60i)
To Top
Trouble shooting: Auto Set Up NG
1. NG appears when you press Auto Set UP. 1. Check Range (Iris control range) if its position is maximum.
If the position is wrong, iris doesn’t close. So ABB doesn’t work.

34.Iris sensitivity control [SENSE] This is used to adjust the iris control range of the
joystick.
35.Iris control range control [RANGE] This is used to adjust the iris control position
(shift the
control range) of the joystick.
Factory Setting: ROP • Reference file operations
– The operations which can be performed include calling the default basic camera data settings and registering and calling the basic user settings selected.
• How to call the settings in the reference files – Scene file is not selected.
1. Factory file
1. Press scene file SW4 while holding down CALL. When the LED of scene file SW4 goes off, it signals the completion of the call operation.
2. User files 1, 2 and 3
1. Press scene file SW1, SW2 or SW3 while holding down CALL. When the LED of scene file SW1, SW2 or SW3 goes off, it signals the completion of the call operation.
– Refer to next page to register user files

How to register Factory Setting/ User File
• How to register settings in the reference files
– 1 Factory file
• Adjust the camera to the status in which the settings are to
be registered, and select the settings. When the scene file
STORE SW is pressed, the LED lights up red. When the
SHIFT and scene file SW4 are now pressed together while
holding down CALL, the STORE SW lamp goes off,
signaling the completion of the registration. The factory file
is the file which contains the settings stored at the factory.
Do not undertake the steps described above because the
registration operation is undertaken by the servicing
department.
– 2 User files 1, 2 and 3
• Adjust the camera to the status in which the settings are to
be registered, and select the settings. When the scene file
STORE SW is pressed, the LED lights up red. When
scene file SW1, SW2 or SW3 is now pressed while holding
down CALL, the STORE SW lamp goes off, signaling the
completion of the registration.

signals received in the transmission between the
camera and CCU are strong enough.
The optical reception strength level is 5.
Orange: The optical reception strength level is 3
to 4.
Red: The optical reception strength level is 1 to 2.
Check the optical connector connections and
mating. If the problem persists, turn off the CCU
power, disconnect the cable between the camera
and CCU, and clean the optical contact area. Use
cotton swabs moistened with alcohol to wipe the
optical fiber part gently.
2. Fan alarm indicator [FAN] This indicates that the CCU’s fan has stopped or
that the camera’s fan is OFF.

are operating normally.
3 Cable alarm indicator [CABLE] This is the camera cable warning indicator.
Lighted: The indicator warns that there is no
connection between the camera and CCU or that the
power supply has been shorted. If it remains lighted,
turn off the CCU’s
main power, and check out the cables and connectors.
If there is no change in the lighting status, contact your
dealer.

Adjusting the lens flange back
1 Mount the lens on the camera. Do not forget to
connect the lens cable at this time.
2 Set the lens iris to manual, and open the iris.
3 Set the lighting in such a way that the appropriate
video output level is obtained at a distance of about
9.9 ft. (3 m) from the flange back adjustment chart.
If the video level is too high, use a filter or shutter.
4 Loosen the screw that secures the F.f (flange
focus) ring.
Note
Depending on the lens concerned, this ring may be
marked as the “F.b” (flange back) ring.
5 Set the zoom ring to the telephoto position either
by manual or electrical means.
6 Shoot the flange back adjustment chart, and turn
the distance ring to adjust the focus.
7 Set the zoom ring to the wide-angle position, and
turn the F.f ring to adjust the focus. Take care not to

The difference between Electrical CC Filter and Optical CC Filter

5600K’s amplifier gain becomes the same
as 3200K’s because color temperature
converts optically.

around 4dB and R
gain is around -6dB

• Lens flare is the light scattered in lens systems through generally unwanted image formation mechanisms, such as internal reflection and scattering from material inhomogeneities in the lens. – Refer to Wikipedia
