Adjustments and Setup During Recording
Setting the Gain Selector Value
When shooting in locations without sufficient brightness, bright images can be obtained by rais-
ing the gain. However, care should be taken as raising the gain also increases the noise.
The gain value for the image amplifier is selected by the GAIN switch. The gain values corre-
sponding to the L, M and H positions of the GAIN switch are set at the MASTER GAIN page of
the setting menu.
Setting the gain selector value
1Set the MENU SET/OFF switch to SET.

(This operation can also be performed using the PAGEoUP/DOWN function.)
3Press the SHIFT/ITEM button repeately to move the cursor to the MASTER GAIN position.
4Press the UP or DOWN button to set the gain value.
The gain value can be set freely regardless of size from among p3, 0, 3, 6, 9, 12, 15, 18,
21, 24 and 30 dB.
When resetting the gain values to the settings when shipped from the factory (LOWr0 dB,
MIDr9 dB, HIGHr18 dB), select MENU INIT. at the DATA RESET page of the setting
menu and press the UP or DOWN button.

Adjusting the White Balance/Black Balance
Adjusting the White Balance
Adjusting the white balance and black balance in the order of AWB (white balance
adjustment)>ABB (black balance adjustment)>AWB will provide a better picture.
Normally, the white balance and black balance do not need to be readjusted even if the power is
turned off and then on again.
However, the white balance must be readjusted when the lighting conditions change.
If black balance and white balance adjustments are started when the display mode is set to “2”
or “3”, messages informing of the adjustment course and results will appear on the viewfinder
screen. Set the display mode to “1” to not display these messages.
ÁSee “Display Mode and Setting Change Message” (page 55) for a description of setting the
display mode.
|Notes{
ÁThe white balance and black balance cannot be adjusted while the setting menu appears on
the viewfinder screen. Therefore, be sure to set the MENU SET/OFF switch to OFF.
ÁABB must be executed again when the MASTER GAIN values on the LOW SETTING, MID
SETTING and HIGH SETTING pages of the setting menu are changed, the S IRIS SW item is
set to o30 dB at the FUNCTION 2/5 page of the setting menu, or the GAMMA (ON/OFF) item
is switched at the FUNCTION 1/5 page of the setting menu.
ÁWith artificial lights, particularly with fluorescent lights and mercury-arc lamps, the strength of
the R, G and B colors changes in synchronization with the power line frequency even if the
brightness of these lights appears to be constant. Especially in areas where the power line fre-
quency is 50 Hz, the vertical synchronizing frequency (approx. 60 Hz) of the TV and the fre-
quency (50 Hz) of the lighting tend to interact. This gives rise to flicker and to a phenomenon
where the hue changes along with the passage of time, and it is it impossible to obtain the
proper white balance.
These phenomena can be reduced by setting the shutter speed to 1/100. For this reason,
wherever the unit is used under fluorescent or mercury-arc lamps and at a frequency of 50 Hz,
the shutter speed must be set to 1/100 and the white balance obtained. This shutter speed of
1/100 should also be used during shooting.
1Set the switches as shown in the figure.
If the settings of the GAIN and WHITE BAL switches are changed, a message informing of
the new setting will appear for about 3 seconds at the setting change message display posi-
tion on the viewfinder screen. (However, the message appears only when the display mode
is set to “3”.)
2Select the FILTER knob setting in accordance with the lighting conditions.
ÁSee FILTER knob (page 15) in the Shooting (Recording)/Playback Function Section for
examples of FILTER knob settings. If the setting of the FILTER knob is changed, a mes-
sage informing of the new setting will appear for about 3 seconds at the setting change
message display position on the viewfinder screen. (However, the message appears only
when the display mode is set to “3”.)
GAIN: Normally, set to 0 dB. When it is too dark,
it is set to the appropriate gain.MENU SET/OFF: OFF

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.
Error messages related to white balance adjustment
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.
|Note{
The white 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.
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 has two memory systems: A and B.
Adjustment values for each filter can automatically be stored in the memory corresponding to
the setting (A or B) of the WHITE BAL switch. The unit contains 4 filters, making a total of
8 (4q2) adjustment values which can be stored.
If FILTER INH on the FUNCTION 2/5 page of the setting menu is set to ON, the A and B sys-
tems can be limited to one memory each.
In this case, the memory contents are not linked to the filters.
