1 Gain Up Control Setting [GAIN: AGC LOW, AGC
HIGH, 0DB, 9DB, 18DB]
When the mode is set to AGC LOW or AGC HIGH, the
AGC with a maximum gain increase of about 9 dB/18
dB operates to control gain up and automatically reg-
ulate the amount of light.
Normally, the mode should be set to 0DB. If a suffi-
cient video output is not obtained in shooting a dark
object even when the iris is fully opened, set the mode
to the 9DB or 18DB position.
• AGC convergence level, photometric method, and
detecting ratio can be set by INITIAL SET menu.
Note:
In using the AGC, it may not function when the iris
switch is in the manual position on the lens with
auto iris ON in the SETUP menu.
2 Iris Control Setting [IRIS: MANU, AUTO]
When the mode is set to AUTO, lens iris is controlled
automatically with lens iris is A (auto) position.
• Auto iris convergence level, photometric method, and
detecting ratio can be set by INITIAL SET menu.
Note:
When the iris control is set to AUTO in this menu,
set the iris switch on the lens to the A (auto) posi-
tion. If the iris is set to MANU in this menu, set the
iris switch on the lens to the M (manual) position.
3 Electronic Shutter Speed Setting [SHUTTER: ELC,
OFF, 1/100, 1/250, 1/500, 1/1000, 1/2000, 1/4000,
1/10000, SYNCHRO]
When the mode is set to ELC, the electronic shutter
speed is automatically controlled to regulate the
amount of light.
When the mode is set to OFF, the electronic shutter is
turned off. The mode is set to between 1/100 and
1/10000 represent respective shutter speeds.
Set the mode to SYNCHRO (synchro scan) for fine
adjustment of shutter speed.
* Refer to the table below for the relative light quantity
required for each setting of shutter speed and synchro
scan.
Shutter Speed Synchro Scan Required Light Ratio
OFF -- 1
1/100 159/525 2
1/250 63/525 4
1/500 31/525 8

1/10000 1/525 160
* ELC convergence level, photometric method, and
detecting ratio can be set by INITIAL SET menu.
When the mode is set to SYNCHRO, shutter speed
can be set by INITIAL SET menu.
Note: If the camera is used with an RCU (RCB), shut-
ter speeds of 1/250, 1/2000, 1/4000, 1/10000 can-
not be selected.
