Power on/off switch (2 position):
- Upper: the video assist is ON and the red LED is lit.
- Lower: power is OFF and the red LED is not lit.
White balance switch (3 position):
- Upper : Auto White Balance is ON. The white balance is adjusted according to the color temperature
transition of the subject. This mode is suitable for shooting with variable lighting.
- Middle: 3200K (fixed) - for indoor shooting under incandescent light.
- Lower: 5600K (fixed) - for outdoor shooting on sunny days.
Gain control set by decimal switch:
"0" - Manual Gain (MG) 0dB
"1" - MG 2dB
"2" - MG 4dB
"3" - MG 6dB
"4" - MG 8dB
"5" - MG 10dB
"6" - MG 12dB
"7" - MG 14dB
"8" - AGC is ON
"9" - FR/A mode, 0dB
The flicker reduction switch is a 3 position switch:
- When set to the lower position, flickerfree mode FF is activated and the green LED is lit. This mode is
designed to produce a flickerfree image for camera speeds ranging from 10 to 150 fps.
- When set to the middle position, flicker reduction is off and the green LED is not lit. The video assist is in
normal mode.
- NTSC - When set to the upper position, flickerfree mode FF30 is activated and the green LED is lit. This
mode provides a 100% flickerfree image when operating at a camera speed of 29.97 fps or 30 fps. In this
mode, flickering is reduced by 70% for camera speeds other than 29.97 fps and 30 fps.
PAL - When set to the upper position, flickerfree mode FF24/25 is activated and the green LED is lit. This
mode provides a 100% flickerfree image when operating at a camera speed of 24 fps or 25 fps.
If the video assist is powered from the camera's accessory connector, flickerfree modes FF , FF30 (NTSC)
and FF24/25 (PAL) will only be active when the camera is running. Once the camera is stopped, normal mode
will resume. If the digital gain control is set to "9", flickerfree FR/A mode will be active even when the camera
is stopped. If the video assist is supplied from the 12 V battery using a cable with a 4 pin XLR connector,
activation of the flickerfree FR/A mode will not depend on whether the camera is running.
The accessory connector which is installed on the side of the video assist is designed to
supply power 12 V DC, 600mA to an LCD monitor.
DIP switches located on the electronics board: By using the DIP switches
located on the electronics board you can flip the image horizontally (mirroring) or
vertically (upside down).
