Description of error
In normal operation, when DCDET2 goes
to "L" (Low) (Not during POWER OFF
condition), F61 appears on FLDisplay
for 1 second and PCONT goes to
"L" (Low).This is due to speaker output
has DC voltage or fan is not working.
In normal operation when DCDET1 is
detected "L" (Low) for two consecutive
times, F76 is displayed on FL for
1 second and after that PCONT will be
turned to "L" (Low). This is due to any of
the DC voltages (+9V, +7V, -7V, +5V,
+5.3V etc.) not available.
Description of error
