CCB-M series
EXTENTIONAL FUNCTIONS
External Synchronization
CCB-M series camera's factory set are Internal sync. only.
They are, however, able to be modified to External synchronization camera, with adding External generator circuit.
1. Change the voltage 9P (EXT.) at CN202 from Low (0V) to High (5V).
2. By this change, IC301 can accept HR/VR signal.
3. Remove R305 and make there Open. R305 is a resister to supply internal clock.
4. Supply 28MHz clock synchronizing HD of 12P on CN202 and with external sync.
source to CN202 16P (CLK IN) .
5. Supply VD signal inputting from External sync. source to CN202 11P (VR).

Gamma (CCB-M25/M25CE, CCB-M35A/M35ACE)
C403 which is on 7P at IC401 on Process board is to be re-mounted into C451. This case, it is necessary to re-
adjust AGC.
Remove C403 on B side. Then mount a same type of chip condenser (0.1µF) at C451 on A side.
GAMMA should be set to "1".
