remedy the problem. Should any problem persist, consult
your nearest Sony dealer.

, The MD may be dirty or damaged. Replace the
MD.
, Only ~/1 and INPUT are operable while the MD
deck is being controlled by a personal computer.

, Moisture has formed inside the deck. Take the MD
out and leave the deck in a warm place for several
hours until the moisture evaporates.
, The deck is not on. Press ~/1 to turn the deck on.
, The deck may not be connected to the amplifier
correctly. Check the connection.
, The MD is inserted in the wrong direction. Slide
the MD into the disc slot with the label side up and
the arrow pointing towards the slot.
, The MD may not be recorded. Replace the disc
with one that has been recorded.
The sound has a lot of static.
, Strong magnetism from a television or a similar
device is interfering with operations. Move the
deck away from the source of strong magnetism.
The deck does not record.
, The MD is record-protected. Slide the record-
protect tab and close the slot.
, The deck is not connected properly to the program
source. Check the connection.
, Select the correct program source using INPUT.
, The recording level is not adjusted properly.
Adjust the recording level.
, A premastered MD is inserted. Replace it with a
recordable MD.
, There is not enough time left on the MD. Replace
it with another recordable MD with fewer recorded
tracks, or erase unnecessary tracks.
, There has been a power failure or the AC power
cord has been disconnected during recording.
Data recorded to that point may be lost. Repeat
the recording procedure.
The deck does not perform Synchro-recording
with a CD player or video CD player.
, The remote supplied with the MD deck is not set
correctly. Reset the remote.

the prescribed remedies, turn off the deck, then reinsert the plug
into the power outlet.
