TEST MODE

● How to enter the test mode

Press and hold the [1] and [3] keys and reset. (While “– – – –” is being displayed, power can be ON for 30 minutes.)

● How to clear the test mode

Reset, momentary power down, Acc OFF, Power OFF, detach the panel.

● Test mode default condition

• Source is STANDBY.

• Display lights are all turned on.

• The volume is at -10dB (The display is 30).

● 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 display ed, pow er can be ON f or 30 minutes.) [CD mechanism information]

• Displays I2C communication condition

• Displays CD mechanism error log

• Displays CD loading error data.

• Displays CD ejection error data

• Displays CD time code error count data (missing count) Displays CD time code error count data (count not updated)

•

[Service information]

• Displays power ON time is displayed

• Displays CD operation time

• Displays number of CD EJECT times

• Displays number of times panel was opened/closed

• Displays forced Power OFF 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 not be retained.)

● Clearing DC offset error detection data

(E2PROM data clearing)

If DC voltage difference (DC offset error) is detected between audio power amplifier (power IC) ± outputs , “DC_ERR_” is displayed on the display. When this occurs, the audio is forcedmute and the display displays only “DC_ERR_”. Once this product detected a DC offset error, even if it is restarted (or reset), its display displays “DC_ERR_”. However, if the error is detected while in Test Mode, it is not saved in E2PROM.

1. Press and hold [3] and [6] keys and reset-start to go into the DC offset error display mode. (While “– – – –“ is being display ed, pow er can be ON f or 30 minutes.)

2. While in ST ANDBY source, the current DC offset error condition is displayed. When detected : “DC_ERR_ _” When not detected: “DC_OK_ _ _”

3. While error condition is being displayed, press [AUTO] key to clear the detection data. (Clear E2PROM)

4. DC offset error display mode is cancelled by resetting. (The last screen will not be retained.)
