If you have any questions or problems concerning your unit that are not covered in this manual, please consult your nearest Sony dealer. Moisture condensation On a rainy day or in a very damp area, moisture may condense on the lenses inside the CD/MD player. Should this occur, the unit will not operate properly. In this case, remove the disc and wait for about an hour until the moisture has evaporated. To maintain high quality sound If you have drink holders near your audio equipment, be careful not to splash juice or other soft drinks onto the unit and CD/MD. Sugary residues on the unit or CD/MD may contaminate the lenses inside the unit, reduce the sound quality, or prevent sound reproduction altogether. Notes on CDs A dirty or defective disc may cause sound dropouts while playing. To enjoy optimum sound, handle the disc as follows. Handle the disc by its edge. To keep the disc clean, do not touch the surface. Do not stick paper or tape on the labeled surface. If you use the discs explained below, the sticky residue can cause the CD to stop spinning and may cause malfunction or ruin your discs. Do not use second-hand or rental CDs that have a sticky residue on the surface (for example from peeled-off stickers or from ink, or glue leaking from under the stickers). There are paste residue Ink is sticky Do not use rental CDs with old labels that are beginning to peel off. Stickers that are beginning to peel away, leaving a sticky residue Do not use your CDs with labels or stickers attached. Labels are attached continue to next page t4 Notes on MDs Since the disc itself is housed in a cartridge, free from accidental contact with your fingers and dust, MDs can withstand a certain degree of the rough handling. However, dirt or dust on the surface of the cartridge or a warped cartridge may cause a malfunction. Observe the following for best results. Never touch the surface of the disc itself by deliberately opening the shutter on the cartridge. When you eject the MD, the shutter may be open. In such a case, close the shutter immediately. Do not expose the MD to direct sunlight or heat sources such as hot air-ducts. Do not leave it in a car parked in direct sunlight where there can a considerable rise in temperature. Make sure the MD is not left on the dashboard or rear tray of a car etc. where the temperature can also be excessive. Do not expose the discs to direct sunlight or heat sources such as hot air-ducts, or leave them in a car parked in direct sunlight where there can be a considerable rise in the temperature inside the car. Before playing, clean the discs with an optional cleaning cloth. Wipe each disc from the center out. Do not use solvents such as benzine, thinner, commercially available cleaners or antistatic spray intended for analog discs. Notes on CD-R discs

• You can play CD-Rs (recordable CDs) on this unit. However depending on the conditions of the recording equipment or the CD-R disc itself, some CD-Rs cannot be played on this unit.

• You cannot play a CD-R that is not finalized (Finalization is necessary for a recorded CD-R disc to be played on the audio CD player).

• You cannot play CD-RWs (rewritable CDs) on this player. When you play 8 cm (3 in.) CDs Use the optional Sony compact disc single adaptor (CSA-8) to protect the CD player from damage.5 Notes on attaching labels Be sure to attach labels on cartridges correctly, as failing to do so may cause the MD to become stuck in the unit.

• Attach the label in a suitable position.

• Remove old labels before putting new ones on.

• Replace labels that are beginning to peel away from the MD. Cleaning Wipe the surface of the MD cartridge from time to time with a soft dry cloth.6 Table of contents Location of controls ................................................. 7 Getting Started Resetting the unit ................................................ 9 Detaching the front panel .................................. 9 Turning the unit on/off ................................... 10 How to use the menu ....................................... 10 Setting the clock ................................................ 10 CD/MD Listening to a CD with CDX-C8050X only ............................... 11 Listening to an MD with MDX-C8500X only .............................. 12 Playing a CD or MD (with optional CD/MD unit) ..................... 12 Playing tracks repeatedly — Repeat Play .............................................. 14 Playing tracks in random order — Shuffle Play .............................................. 14 Labeling a CD — Disc Memo (For a CD unit with the custom file function).................................... 15 Locating a disc by name — List-up (For a CD unit with the custom file function or an MD unit) ....................... 16 Selecting specific tracks for playback — Bank (For a CD unit with the custom file function) ................................................. 17 Radio Memorizing stations automatically — Best Tuning Memory (BTM) ................. 18 Memorizing only the desired stations ........... 18 Receiving the memorized stations.................. 19 Storing the station names — Station Memo .......................................... 20 Locating a station by name — List-up ...................................................... 21 DSP Setting the equalizer ......................................... 21 Selecting the listening position ....................... 22 Selecting a soundstage menu — Dynamic Soundstage Organizer (DSO) .......................................... 23 Adjusting the balance (BAL) ........................... 23 Adjusting the front and rear fader ................. 24 Adjusting the volume of the subwoofer(s).... 25 Listening to each programme source in its registered DSO — Source Sound Memory (SSM) ............... 25 Selecting the spectrum analyzer ..................... 26 Other Functions Labeling the rotary commander ..................... 26 Using the rotary commander .......................... 27 Attenuating the sound ..................................... 28 Changing the sound and display settings ..... 29 TV/Video Watching the TV ............................................... 30 Watching a video .............................................. 30 Memorizing TV channels automatically ....... 30 Memorizing only the desired TV channels ... 30 Storing the TV channel names ........................ 31 Displaying the information stored on discs .............................................. 31 Watching the TV or video while listening to a CD or MD — Simultaneous Play .................................. 32 Additional Information Maintenance ....................................................... 33 Dismounting the unit ....................................... 34 Specifications ..................................................... 35 Troubleshooting guide ..................................... 367 Location of controls Refer to the pages listed for details. 1 Volume control dial 2 MENU button 10, 13, 15, 16, 17, 18, 19, 20, 22, 24, 25, 26, 29, 30, 32 3 DISC/PRST +/– (cursor up/down) button 10, 13, 15, 16, 17, 18, 19, 20, 21, 22, 24, 25, 26, 29, 30, 32 During radio reception: Preset stations select 19 During CD/MD playback: Disc change 13, 16 During TV reception: Channel select 30 4 Z (eject) button (located on the front side of the unit behind the front panel) 11, 12 5 DSPL (display mode change) button 12, 13, 15, 20 6 LIST button Station Memo 20 Disc Memo 15 List-up 16, 21, 31 7 SOURCE (Tuner/CD/MD/TV) button 10, 11, 12, 13, 16, 18, 19, 21, 22, 23, 24, 25, 26, 30, 32 8 Display window 9 OPEN button 9, 11, 12, 33 0 DSO button 23 qa SOUND button 21, 22, 23, 24, 25 qs Reset button (located on the front side of the unit behind the front panel) 9 qd OFF button* 9, 10, 11, 12 qf SEEK/AMS –/+ (cursor left/right) button 10, 13, 15, 17, 19, 20, 21, 22, 23, 24, 25, 26, 29, 30, 32 Seek 18, 19 Automatic Music Sensor 13 Manual Search 13, 19 qg ENTER button 10, 13, 15, 16, 17, 18, 19, 20, 21, 22, 24, 25, 26, 29, 30, 32 qh MODE button During radio reception: BAND select 18, 19 During CD or MD playback: CD/MD unit select 12, 16 During TV reception: TV1/TV2 select 30 qj Receptor for the card remote commander qk Number buttons During radio reception: Preset number select 18, 19 During CD/MD playback: (1) REP 14 (2) SHUF 14 During TV reception: Preset number select 30
