The messages shown in the figures below will be displayed if the color temperature of the
subject is lower than 2500K or higher than 5600K.
The down [] arrow indicates a color temperature which is lower than the one displayed;
conversely, the up [] arrow indicates a color temperature which is higher than the one dis-
played.
Note
If a lens equipped with the automatic iris function is used, the iris may experience hunting
1). In
these cases, adjust the iris gain knob (the knob marked IG, IS, S, etc.) on the lens.
See the Handling Instructions for the lens for a detailed description.
1) Hunting:The auto iris responds repeatedly causing the image to become darker and brighter.

Adjusting the White Balance/Black Balance
When the White Balance Cannot be Automatically Adjusted
An error message will appear on the viewfinder screen.
(The message appears when the display mode is set to “2” or “3”.)
The displayed messages are as follows.

Meaning
The color temperature is too
high.
The color temperature is too
low.
There is insufficient
illumination.
There is too much illumination.
The shooting conditions are

place under fluorescent lighting
or the camera is not being held
or pointed properly, etc.).
The CC/ND FILTER knob is
not set correctly.
Treatment
Select an appropriate filter
Select an appropriate filter.
Increase the illumination or
gain.
Decrease the illumination or
gain.
If flickering is a problem, turn
the SHUTTER switch to ON
and stabilize the shooting
conditions.
Set the CC/ND FILTER knob
correctly.
If the above error messages appear, carry out the respective treatment attempt to adjust the white
balance again.
If the error message continues to appear even after repeated attempts, consult your dealer.
Notes
The white balance will not be adjusted while the setting menu is displayed on the viewfinder
screen.
The MENU SET/OFF switch must be set to the OFF position to make this adjustment.
In rare instances the white balance adjustment may not be possible and an NG display will
appear.
In a case like this, proceed with the white balance adjustment again.
When there is no Time to Adjust the White Balance
Set the WHITE BAL switch to PRST.
The white balance for the filter is automatically adjusted according to the setting position of the
FILTER knob (outside).
White balance memories
The white balance memories fall into two categories, A and B.
The number of A and B memories is limited to 1 each when FILTER INH is set to ON (default
setting) on the “CAMERA SW MODE” SUB menu page of MAIN menu screen 2 of 4.
In this case, the contents of the memories are not linked to the filter.
However, when FILTER INH is set to OFF, the adjustments values for each filter can be automat-
ically stored in the memory corresponding to the WHITE BAL switch setting (A or B).
The unit contains 4 filters, making a total of 8 (42) adjustment values which can be stored. 
						

							–74– Adjusting the White Balance/Black Balance
When the ON setting has been selected for FILTER INH
When the automatic white balance is adjusted, the color temperature and filter number at the time
are displayed.
When the filter is now turned, the new color temperature and filter number are displayed.
The white balance is almost perfectly adjusted if the subject is illuminated by a light with a color
temperature close to the one displayed.

If the color temperature of the subject in this state is close to 5.2K, the white balance is adjusted,
and so operation is now possible.
Change to filter (3).
“5.2K (1)” (see Note) appears on the display.
Note:
This display indicates that the AWB was adjusted using filter (1).
Use filter (1) to adjust the AWB for objects with an illumination color
temperature of 3200K.AWBAOK 3.2K

“3.2K (1)” appears on the display denoting the status when the
AWB was first adjusted.

The black balance must be adjusted in the following cases.
When the unit is used for the first time
When the unit is first used after an extended period of non-use
When the unit is used under conditions where the ambient temperature has changed by a wide
margin
When the gain selector value is changed
When the super gain setting has been changed using the SUPER GAIN button
When the gamma ON/OFF is changed

Adjustment is completed after a few seconds (the following message appears) and the ad-
justment value is automatically stored in the memory.
Notes
Check that the lens connector is connected and that the iris of the lens is set to CLOSE.
During black balance adjustment, the iris automatically goes to the shaded status.
During black balance adjustment, the gain selector circuit switches automatically.
In addition, flicker and noise may appear on the viewfinder screen, but this does not indicate a
malfunction.
The black balance cannot be adjusted while the setting menu is displayed on the viewfinder
screen. Therefore, be sure to set the MENU SET/OFF switch to OFF.
If the black shading is not satisfactory even when the “ABB OK” message appears, open the
“AUTO SHADING” SUB menu page of MAIN menu screen 4 of 4, and adjust the black shading.
(See page 141.)
The black shading adjustment is performed automatically when the AUTO W/B BAL switch is
held down at the ABB position for 10 or more seconds.
When the super gain is set to ON, the black balance is performed at the preset position in the
white balance memory.

Setting the Electronic Shutter
Shutter Modes
The shutter modes which can be used with the unit’s electronic shutter and the shutter speeds
which can be selected are as follows.
Shutter modes and shutter speeds which can be selected
Mode
Standard
SYNCHRO
SCAN
SUPER V
Shutter speed
1/100, 1/120, 1/250, 1/500,
1/1000 and 1/2000
(seconds)
Range from 60.8 Hz to
250 Hz
Application
This mode is used to shoot clear images of
quickly moving subjects.
This mode is used to reduce horizontal stripe
patterns for monitor screens with a vertical
scanning frequency of 60 Hz or more.
This mode is used to increase the vertical
resolution.
Notes
Increasing the shutter speed lowers the camera sensitivity regardless of electronic shutter
mode.
If the iris is set to AUTO, the iris opens and the depth of the focuses decreases as the shutter
speed rises. 
						

							–78– Setting the Electronic Shutter
Setting the Shutter Mode/Speed
The shutter speed during shutter mode and standard mode is set by the SHUTTER switch.
During SYNCHRO SCAN mode, the shutter speed can be set beforehand at the SYNCHRO
SCAN page of the setting menu. In the SYNCHRO SCAN mode, the shutter speed can easily be
changed using the SYNCHRO (“	” and “
”) buttons. (It can also be set using the UP or DOWN
button.)
The shutter speed selection range can be limited to the required range and whether to use
special operation modes (SYNCHRO SCAN or SUPER V) can be selected at the SHUTTER
SPEED page of the setting menu.
1Set DISP MODE on the “VF DISPLAY” SUB menu page of MAIN menu screen 2 of 4 to “2” or
“3” by following the steps outlined in “Changing the Display Mode” (page 62).
2Press the SHUTTER switch from the ON position to the SEL side. The current shutter setting
appears in the setting change message display position on the viewfinder screen.
Ex.: 1/120, 1/60.8, etc.
3Press the SHUTTER switch to the SEL side repeatedly until the desired mode or speed ap-
pears. When all modes and speeds can be displayed, the display changes in the order shown
below. If the required shutter speeds and modes have been designated beforehand, only the
designated speeds or modes appear.
When the unit is shipped from the factory, SUPER V mode is not specified and is therefore
not displayed.
