• Dust on the lens may prevent the unit from operating properly. Be sure to close the disc compartment lid after inserting and ejecting an MD. Note on mechanical noise The recorder gives out mechanical noise while operating, which is caused by the power-saving system of the recorder and it is not a trouble. Notes on recording Mechanical shock or vibration Do not subject the recorder to strong mechanical shock or continuous vibration while recording. The sound may be skipped or recording may stop.
Do not remove the black sheet unless you are disposing of this product, or it may not work properly. If you have any questions or problems concerning your recorder, please consult your nearest Sony dealer.
Troubleshooting Should any problem persist after you have made these checks, consult your nearest Sony dealer. Symptom Cause/Solution The recorder does not work or works poorly. • Moisture has condensed inside the recorder. b Take the MD out and leave the recorder in a warm place for several hours until the moisture evaporates. • The dry batteries or rechargeble battery are weak (b "LOW BATT" flashes). b Replace the dry batteries or recharge the battery (page 6 or 27).
Symptom Cause/Solution Sound has a lot of static. • Strong magnetism from a television or such device is interfering with operation. b Move away from the source of strong magnetism. The REC button stays pressed down. • You pressed the REC button while the recorder was not connected to the power source. b Install dry batteries or a rechargeable battery. Or connect to house current with the AC power adaptor (page 6 or 27). Cannot erase the track marks.
System limitations The recording system in your MiniDisc recorder is radically different from those used in cassette and DAT decks and is characterized by the limitations described below. Note, however, that these limitations are due to the inherent nature of the MD recording system itself and not to mechanical causes. Symptom Cause "TR FULL" appears even before the disc has reached the maximum recording time (120 or 148 minutes in monaural, 60 or 74 minutes in stereo).
Error messages If the following error messages flash in the display window, check the chart below. Meaning/Remedy BLANKDISC •An MD with no recording on it is inserted. b Insert a recorded MD. BUSY •You tried to operate the recorder while it was accessing the recorded data. b Wait until the message goes out (in rare cases, it may take 2–3 minutes). CANNOT •You tried to erase a track mark while playing the MD or at the beginning of the first track.
Error message Meaning/Remedy TEMP OVER • Heat has built up in the recorder. b Leave the recorder to cool down. TR FULL • There is no more space for new data when you are editing the MD. b Erase unneccessary track numbers or tracks (page 24 or 25).

How the MiniDisc got so small Shock-Resistant Memory The 2.5-inch MiniDisc, encased in a plastic cartridge that looks like a 3.5inch diskette, uses a new digital audio compression technology called ATRAC (Adaptive TRansform Acoustic Coding). To store more sound in less space, ATRAC extracts and encodes only those frequency components actually audible to the human ear. One major drawback of optical read systems is that they can skip or mute when subjected to vibration.
