1) SW1(L/L) :
Set to OFF, the camera activates the internal synchronization mode and set to ON, the power
synchronization mode. If you connect multi cameras to the sequential switcher to enter the
automatic conversion mode, the screen will bounce every screen while the camera stays in
E
INT(internal synchronization). Such bouncing phenomena may be cleared and screen conversion
becomes smooth by setting the L/L switch to ON and using the INT/DEC switch to control the
vertical synchronous phase.
If you want to control the vertical synchronous phase with the INT/DEC switch when L/L is set
to ON, you shall set SW4 to AWB ON.
In case of DC12V, INT(internal synchronizer) will be fixed without regard to ON/OFF of L/L.
2) SW2(ELC) :
Use this switch with the Manual Iris Lens. While this switch is ON, the speed of the electronic
shutter varies with the brightness of the subject from 1/60(50) to 1/100,000 sec for automatically
controlling the brightness of the screen. However, with the Auto Iris Lens (DC or Video Control),
be sure to switch OFF.
Color Rolling may occur in this mode. In that case, input AC power source to the camera and
select SW1 "ON".
(NTSC : 60HZ, PAL : 50HZ)
3) SW3(FL):
This is to prevent flicker on the screen when NTSC system is used in 50HZ power supply region
and PAL system is used in 60HZ power supply region. That is to prevent shaking on the
screen resulted from the discordance of the vertical sync frequency and the flicker frequency of
the illumination. While this switch is ON, the electronic shutter is fixed to 1/100sec (NTSC) or
1/120 sec (PAL).
4) SW4(AWB):
When setting up ON, the color of screen is adjusted automatically in accordance with the change
of lighting color temperature by the change of outer environment. (ATW) If the lighting condition is
steady, OFF setting is available. The camera memorizes the lighting color temperature at the
time when the switch setting is changed from ON to OFF, and the camera color is adjusted to the
memorized color temperature. (AWC) If the lighting color temperature is changed and you want
to make the camera be memorized/operated with the changed color temperature, re-operate the
switch On/Off operation. However, be aware that an error may occur under the following
conditions.
First, a case that the subject is big, single color of the high chroma, and in the center of
the screen or a case with almost no white color on the screen.
Second, a case with a specific illumination such as a natrium lamp
