1.   Select the pan/tilt head system using the CONTROL/ 

PREVIEW MONITOR OUT SEL button.

2.   Shoot a white object (such as a white wall or 

handkerchief) to fill the whole screen using the pan/tilt 
head system currently selected.

Do not allow shiny, reflective or very bright objects to 
appear on the screen.

3.   Press the WHITE BAL A button, and press the AWC 

button. The AWC button’s lamp flashes, and the white 
balance is automatically adjusted. Once the adjustment 
has been performed correctly, the lamp goes off, and the 
conditions set are entered in channel A. 
The AWC button’s lamp will remain lit if it was not 
possible for the adjustment to be performed. In this case, 
change the brightness, iris, object, light source, etc., and 
perform the adjustment again.

The AWC button’s lamp goes off even if the white 
balance adjustment was not performed correctly in 
cases where a pan/tilt head system other than the  
AW-PH350, AW-PH360 or AW-PH650 is being used.

4.   Similarly, enter the conditions set for channel B using the 

WHITE BAL B button.

5.   Select the next pan/tilt head system using the 

CONTROL/PREVIEW MONITOR OUT SEL button, and 
continue adjusting the white balance in each system 
concerned.

White balance adjustment

The white balance must be adjusted when the equipment 
is used for the first time, when it has not been used for a 
prolonged time or when the lighting conditions or brightness 
has changed.
The white balance conditions can be entered in advance 
into channels A and B.
If the equipment is to be used under conditions which are 
identical to the entered settings, it means that no further 
adjustment need be undertaken since the white balance 
will be set simply by pressing the WHITE BAL A button or B 
button once the white balance has been adjusted.
When the white balance is adjusted again, the previously 
entered settings will be deleted and replaced by the new 
conditions.

Automatic adjustment of white balance

1.   As with the procedure for automatic adjustment, select 

the pan/tilt head system using the CONTROL/PREVIEW 
MONITOR OUT SEL button, and shoot a white object to 
fill the whole screen.

2.   Connect a waveform monitor or colour monitor to the 

VIDEO/Y OUT connector on this unit that corresponds to 
the pan/tilt head system currently selected.

3.   Press the WHITE BAL A button to select the channel A 

memory.

4.   Press the R/B GAIN/PED button, and set it so that the 

following item appears on the LCD panel.

GAIN            0dB

   R: 0    B: 0

5.   Use the menu setting control (L) to adjust the gain of the 

R (red) channel, and use the menu setting control (R) to 
adjust the gain of the B (blue) channel.

6.   Similarly, enter the conditions set for channel B using the 

WHITE BAL B button.

7.   Select the next pan/tilt head system using the 

CONTROL/PREVIEW MONITOR OUT SEL button, and 
continue adjusting the white balance in each system 
concerned.

Manual adjustment of white balance

When the WHITE BAL ATW button is pressed during 
shooting, the ATW button’s lamp comes on, compensation 
is provided so that the white balance will be automatically 
adjusted even if the light source or colour temperature has 
changed in order to minimize an unnatural appearance in 
the resulting images.

If nothing white is shown on the screen, it may not 
be possible for the white balance to be compensated 
properly.
Similarly, with some light sources or colour temperatures, 
it may not be possible for the white balance to be 
compensated properly.
