Notes:
• When AGC GAIN is set to 9 or 18 dB or when SUPER AGC is
set to ON, dark parts of the picture may look noisy. This is be-
cause sensitivity increased and it is not a malfunction.
• With SUPER AGC set to ON, the level reaches 18 dB even with
AGC GAIN at 0 or 9 dB. AGC GAIN display does not change
however.
• The camera ID level can be adjusted by turning SUPER AGC on
and off.
• The response of the SUPER AGC may be retarded against the
acute level changes.
<Setting in MANUAL mode>
1. Press SET button in MANU ( 1/50 [1/60] ) mode, and ( ) are
removed to allow setting.
2. Change the shutter speed with or button.
3. Press SET button again, and ( ) comes out to finish shutter
speed setting.
If the AUTO mode or a high-speed shutter mode is selected under
fluorescent lighting, the picture could flickering or the white bal-
ance could be un-stable.
Set according to whether the electronic
shutter is to be switched manually or au-
tomatically.

In such a case, the flickering and white balance variation can be
improved by setting the shutter speed to 1/100 [1/120] in an area
where the local power supply frequency is 50 [60] Hz or to 1/60 [1/
50] in an area where it is 60 [50] Hz. E type [U type]
Note:
When shutter speed is higher, goes to worse the smear which
is a phenomenon inherent to CCDs.
