MPEG-audio bit stream data stored in ROM (IC803) are trans-
ferred to the AV Decoder (IC203) via ARP (IC806), and analog
audio data are output from 2ch DAC (IC215).
In such a case, first the mute by I/O of SH (IC805), then the mute
by setting AV Decoder (IC203), and by setting DAC are turned on
respectively to output low frequency tones.
Finally, the mute is turned off to output high frequency tones.
Checking is finished when high frequency tones are heard.
Low tones will be heard before this checking finished, if the mute
is not effective.
To make sure which mute is not effective, the check should be
repeated while paying attention to the message.
If no error is found, the message is displayed to prompt for key

the select switch. To make sure, they are outputagain by turning
off the select switch. If normal, the tones in the first check are
same as in “MPEG Audio Analog Output”, but the sound level in

The drive can be automatically adjusted, except disc change and
tangential skew adjustment. For a disc, use the disc for adjust-
ment.
In case of abnormality, press the [stop] key to stop adjustment.
If the drive does not stop, prevent secondary failure by taking
proper action such as disconnection of the power cable. This ad-
justment should be made after repair is finished and no trouble is
present in the drive.
A trouble, if present, causes NG and the adjustment to be aborted.
As the secondary failure could occur, perform automatic adjust-
ment after the drive is completely repaired.
