● How to enter the Test mode

Procedure

Note

Press and hold the [1] key and [3] key and reset.

All lamps blinks when it is detected that the sub-clock resonator is disconnected.

When having started up in the Test mode, change the LINE MUTE inhibition time from 10 seconds to 1 second.

In the Test mode, do not write the detection information in the Data Flash ROM even if a DC Offset Error is detected.

Do not operate the DEMO mode in the Test mode, CD Mechanism Error Log Information Clear Mode, or DC Offset Error Detection Information Clear Mode.

Also, when the source is STANDBY in the above mode, do not display DEMO ON/OFF switching items in the FUNCTION. In the Test mode, the forced disc ejection operation is prohibited.

● How to clear the Test mode

Procedure
