INDICATION OF PROTECTION INFORMATION

■

If any of indicators shown below fl ashes after turning on the power to this unit, it means that the protection func-
tion is at work and normal operation is not available.

●

Details of Protection Information

a. DC protection

Cause: Abnormal DC voltage of amplifi er output L/R
Normal value: 0.312 to 2.327 V
Detection port: PRD (58 pin of microprocessor IC15)
Detected at: Amplifi er output L/Rch of MAIN P.C.B.

b. I protection

Cause: Excess current fl ow into amplifi er
Normal value: Low (0 V)
Detection port: PRI (56 pin of microprocessor IC15)
Detected at: Amplifi er output L/Rch of MAIN P.C.B.

c. TH protection

Cause: Abnormal temperature of heat sink.
Normal value: 0.3 to 1.4 V
Detection port: TH_R (57 pin of microprocessor IC15)
Detected at: Heat sink temperature detection IC401 of MAIN P.C.B.

MUSIC indicator flashing: DC protection

MIC indicator flashing: TH protection

ECHO indicator flashing: I protection

KEY CONTROL indicator flashing in red/green alternately
