EXTENTIONAL FUNCTIONS
Modification of Auto Gain Control
Preset is AGC ON.(CCB-M25/CE, CCB-M35A/CE)
AGC OFF
Remove R406 (0
Ω
) at 16P of CXA1310AQ on Process board, then make there OPEN. GAIN is fixed.
AGC Manual Control
Remove R406, R451 and R452. Supply the proper voltage to 3P at CN203 (GAIN CONT.).

AGC Manual Control characteristics
Electronic Shutter Control
Preset is normal shutter speed ( EIA : 1/60 sec., CCIR : 1/50 sec.)
With reference below table, connect 5P (D0), 6P (D1) and/or 7P (D2) at CN202 to GND, as preset of each
terminals are high.
On the PSB-915IA, short lands for settling the electronic shutter by connecting the lands. The terminal connect to
ground.
