6 DIP switches for setting functions

1 & 2 - WHITE BALANCE switches

Select the white balance setting according to the lighting conditions.
3200K (fixed): for indoor shooting under incandescent light.
5600K (fixed): for outdoor shooting on sunny days.
ATW (auto tracing white balance): the white balance is adjusted according to the color temperature transition of the subject. This mode is suitable for shooting with variable lighting.
MAN (manual): Select this position when you want to adjust the red color with the R control and the blue color with the B control.

3 & 4 - SHUTTER speed switches.

Set the SHUTTER speed switches to select the desired shutter speed.
1/60 s (NTSC), 1/50 s (PAL)
1/1000 s
1/100 s (NTSC), 1/120 (PAL)
CCD IRIS: the video assist automatically adjusts the shutter speed according to amount of incident light, thus regulating the level of the video signal.

5 - AGC (auto gain control) ON/OFF switch.

ON: Auto gain control
OFF: 0 dB

6 - Y/C / VBS switch (to use this option you need a special cable).

V/C: Select this position to output the Y/C separated signal.
VBS: Select this position to output the VBS composite signal.

R control for manual white balance adjustment.
This control is effective when the WHITE BALANCE switches are set to MAN. Adjust the red color by turning the control.

B control for manual white balance adjustment.
This control is effective when the WHITE BALANCE switches are set to MAN. Adjust the blue color by turning the control.
