Function Switches

1) SW1 (LL):
When set to OFF, the camera operates in the Internal
Sync mode. When set to ON, it operates in the Power
Sync mode. If the camera is set to INT (Internal Sync)
when monitoring in the Auto Switching mode with more
than one camera connected to a sequential switcher, etc,
the jump of the screen will occur each time of screen
switching. To switch the screen gently without a jump, set
the camera to LL and adjust the Vertical Sync Phase using
the INC/DEC switch.

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 to
1/120,000 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".

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
※ To adjust the Vertical Sync Phase using the INC/DEC
switch in LL mode, the SW4 must be set to AWB "ON".
※ For DC 12V, the INT/LL mode is fixed to INT.
