Power ON:
FRONT BOARD
Standby Key 1214 → Line KEY2 → Microprocessor 7001.
Microprocessor 7001 sends an I
2
C command to Shiftregister
7403 on
AF9 BOARD
D5 (7403/11) = AMP_ON is set to high level.
Line AMP_ON is connected to the
POWER BOARD
If AMP_ON is high → power amplifiers 7301 and 7302 are
switched on.
CDR ON:
FRONT BOARD
CDR Key 1002 → Line KEY2 → Microprocessor 7001.
Microprocessor 7001 sends an I
2
C command to Shiftregister
7403 on
AF9 BOARD
D1 (7403/6) = VCD/CDR_ON is set to high level.
Line VCD/CDR_ON is connected to the
POWER BOARD
On the Power Board the line is called VCD_ON.
If this line is high → +5V_VCD and +12V_CDR are switched
on.
CDR MODULE gets supply voltages via 1312 → 1214.
