● Initializing AUDIO-related setting value

Press the [ ] key in the STANDBY source and reset the AUDIO setting value to the test mode default value.

● Other

•When started in Test Mode, duration of prohibiting LINE MUTE shall be changed from 10 seconds to 1 second.

•When in Test Mode, when DC offset error detection is run, the detection information is not written into the E2PROM.

● Clearing CD mechanism information and service

information (E2PROM data clearing)

1.While pressing the [Q] key and [ATT] key, reset-start to start CD mechanism and service information initialization.

(While “– – – –“ is being displayed, power can be ON for 30 minutes.)

[CD mechanism information]

•Displays I2C communication condition

•Displays CD mechanism error log

•Displays CD loading error data.
