Initializing AUDIO-related setting value
Press the [ ] key in the STANDBY source and reset the AU-
DIO 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.

2. After the initialization process is completed, the following is
displayed.
When successfully completed : "CD_O"
When finished but unsuccessful : "CD_X"
∗ CD mechanism information clearing is no good.
3. This mode is cancelled by resetting. (The last screen will

Clearing DC offset error detection data
(E2PROM data clearing)
1. Press and hold [3] and [6] keys and reset-start to go into
the DC offset error display mode.
(While "– – – –" is being displayed, power can be ON for 30
minutes.)
2. While in STANDBY source, the current DC offset error con-
dition is displayed.
When detected
When not detected : "DC_OK_ _ _"
3. While error condition is being displayed, press [AUTO] key
to clear the detection data. (Clear E2PROM)

While in test mode and all lights are lit (STANDBY), press and
hold [1] key and press [6] key for 3 seconds or longer.
