FUNCTION SWITCH-1
SW1(ELC)
Use this for the manual iris lens. If set to ON, the electronic
shutter speed varies between 1/60 and 1/120,000 second
to keep the screen brightness proper. However, you must
position this switch to OFF if you are using the auto iris
lens (DC control type). Because, in this mode, the camera
can show the color rolling effect when operating under the
mechanical fluorescent lightning. If this happens, apply the
AC power and set the L/L to "EXT". (NTSC: 60Hz, PAL:
50Hz)
SW2(BLC)
Use to compensate for a display that is too bright or too
dark when indoor lighting or windows reflects against the
subject. Set to ON for these conditions.

3. FL(Flickerless)
4. AWB
SW3(FL)
It is an anti-flicker system that prevents the flickering of the
image due to mismatch between the vertical sync frequency
and the on-off frequency of lighting.
It is used when the camera and broadcasting system within
its own region do not match each other. If set to ON, the
electronic shutter speed stays at either 1/100sec (NTSC) or
1/120sec (PAL).
If SW1 (ELC) is set to ON, the anti-flicker system
does not work even if SW3 is positioned to ON.
SW4(AWB)
ON(ATW): It automatically adjusts the image color
according to the temperature change of the
lightning color. Under a very irregular lightning
condition (such as car headlight), if set to ON,
it captures a subject normally (white).
OFF(AWC): It remembers the normal color temp switch
with the OFF to operate at a certain white
balance level.
Note that AWB can cause an error in the following
conditions:
- If a big subject of a uniform color with a high
saturation exists in the center of the screen or
if few part of the image is in white.
- If lighting is made of special material like
sodium.
