45、hod of system reset, power up/down via mains switch and standby mode has changed from that of the CD73. When the CPU is reset by the LM809, IC300 on the display board, after a short delay, approx. 200mS, the STANDBY line goes HIGH. The STANDBY line, in turn, generates 2 more timed signals. 1. XRST,

46、the system reset line, which goes HIGH 1s after the standby line goes high, and is also gated into the 10DAC power-on mute cct. 2. PWRDN, which switches off all the unregulated supplies except that which drives the +5VD to the CPU. This delays the LV power being switched off by 1s after the output i
