Is DSP writing mode entered? (Simultaneously press and hold the ENTER and VIDEO Multi-Zone &
Source/REC SEL ON/OFF keys.)
Is DIR locked? → You can check this on the Signal Select indicator if the input is set to Auto and
Digital. If DIR is not locked, check the input function and digital connections between the player
and this unit.
Is the stream (Track No., etc.) being played back correct?
Are compressed audio signals, such as WMA, being input when or after writing mode is entered ?
→ As soon as the compressed audio signals are input, writing mode is exited. It is recommended
that playback be paused at the beginning of the track of a updating stream then writing mode is
entered by simultaneous pressing of the keys. Release Pause mode after entering of writing mode
is confirmed.
Is the volume control of the receiver set to -∞ dB? If not, set it to -∞ dB (- - -).
Reset the receiver then enter writing mode.
Note: All the user data stored in the receiver are cleared when the receiver is reset.
Is the track played back from the beginning to the end?
→ With the receiver in writing mode, be sure to play back the stream track twice.
If an error is generated because any scratches on the disc, "OK" is not displayed.
→ In such a case, play back the same stream stored on another track as backup.
