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
entry.
