RX-8010VBK Adjustment method Tuner section 1.Tuner range 87.5MHz~108.0MHz AM(MW) 530kHz~1710kHz Power amplifier section Adjustment of idling current Measurement location B2204-B2205(Lch) , B2213-2214(Rch) Adjustment part VR787(Lch) , VR788(Rch) Attention This adjustment does not obtain a correct adjustment value immediately after the amplifier is used (state that an internal temperature has risen).
RX-8010VBK Self-diagnose function 1. Detection of abnormal power supply and voltage When the power is turned ON, if an abnormality is detected during the signal input at the A/D port (IC901, pin 2-5, 7) for one second continuously, the status will become STANDBY mode immediately.

RX-8010VBK 4. Self-diagnose To enter the self-diagnose mode, put the power plug in the socket while pressing SETTING key and UP key together simultaneously, then turn the power ON. With the UP/DOWN key operation, DSP microcomputer, ROM No.of system microcomputer as well as working status of DSP can be displayed for five seconds.
