System (RDS)
(European model only)
What is the Radio Data System?
Radio Data System (RDS) is a broadcasting service that allows radio stations to send additional information along with the regular program signal. This tuner offers convenient RDS features such as station name. RDS is available only on FM stations.*
Note
RDS may not work properly if the station you are tuned in is not transmitting the RDS signal properly or if the signal is weak.
* Not all FM stations provide RDS service, nor
do they provide the same type of services. If you are not familiar with the RDS system, check with your local radio stations for details on RDS services in your area.
Receiving RDS broadcasts
Simply select a station from the FM band.
When you tune in a station that provides RDS services, the station name appears in the display.
To check the RDS information
While receiving an RDS station, press DISPLAY repeatedly.
RDS information appears on the display.

Troubleshooting

Should you encounter a problem with your system, do the following:
1 Make sure the power cord and
speaker cords are correctly and firmly connected.
2 Find your problem in the checklist
below, and take the indicated corrective action.
If the problem persists, contact your nearest Sony dealer. Note that if service personnel changes some parts during repair, these parts may be retained.
When the "/1 indicator flashes
Immediately unplug the power cord, and check the following items.
• If your system has a voltage selector, is the voltage selector set to the correct voltage?
• Are you using only the supplied speakers?
• Are the + and – speaker cords short­circuited?
• Is anything blocking the ventilation holes of the unit?
After checking the above items and fixing any problems, plug in the power cord again and turn on the system. If the STANDBY indicator still flashes, or if the cause of the problem cannot be found even after checking all the above items, consult your nearest Sony dealer.
The display starts flashing as soon as you plug in the power cord even though you have not turned on the system.
• Press DISPLAY once while the system is turned off. The demonstration disappears.
The clock or timer setting is canceled.
• The power cord is disconnected or a power failure occurred. Redo “Setting the clock” (page 16). If you have set the timer, redo “Using the timer” (page 36).
“– –:– –” appears in the display.
• The clock is not set. Set the clock (page 16).
• A power failure has occurred. Set the clock (page 16) and timer settings (page 36) again.
There is no sound.
• Turn MASTER VOLUME clockwise (or press VOLUME + repeatedly on the remote).
• The headphones are connected to the PHONES jack.
• Check the speaker connections (page 15).
• There is no audio output during Recording Timer.
There is no sound from the subwoofer.
• Check that the subwoofer is connected securely and correctly to the unit.
There is no microphone sound.
• Turn MASTER VOLUME clockwise (or press VOLUME + repeatedly on the remote) or turn MIC LEVEL clockwise to adjust the microphone volume.

Precautions

Discs that this system CAN play
• AUDIO CD
• CD-R/CD-RW (audio data/MP3 files)
Discs that this system CANNOT play
•CD-ROM
• CD-R/CD-RW other than those recorded in AUDIO CD format or MP3 format conforming to ISO9660 Level 1/Level 2, Joliet in the expansion format
• CD-R/CD-RW recorded in multisession that have not ended by “closing the session”
• CD-R/CD-RW of poor recording quality, CD-R/CD-RW that have scratches or are dirty, or CD-R/CD-RW recorded with an incompatible recording device
• CD-R/CD-RW which is finalized incorrectly
• Discs containing files other than MPEG 1 Audio Layer-3 (MP3) files
• Discs of non-standard shape (for example, heart, square, star)
• Discs that have adhesive tape, paper, or sticker attached to them
• Rental or used discs with attached seals where the glue extends beyond the seal
• Discs that have labels printed using ink that feels tacky when touched
Notes on discs
• Before playing, wipe the disc with a cleaning cloth from the center out to the edge.
• Do not clean discs with solvents, such as benzine thinner, or commercially available cleaners or anti-static spray intended for vinyl LPs.
• Do not expose discs to direct sunlight or heat sources such as hot air ducts, nor leave it in a car parked in direct sunlight.
On safety
• The unit is not disconnected from the mains as long as it is connected to the AC outlet, even if the unit itself has been turned off.
• Completely disconnect the power cord (mains lead) from the wall socket (mains) if it is not going to be used for an extended period of time. When unplugging the unit, always grip the plug. Never pull the cord itself.
• Should any solid object or liquid get into the system, unplug the system, and have it checked by qualified personnel before operating it again.
• AC power cord must be changed only at the qualified service shop.
On placement
• Do not place the system in an inclined position or in locations that are extremely hot, cold, dusty, dirty, or humid or lacking adequate ventilation, or subject to vibration, direct sunlight or a bright light.
• Be careful when placing the unit or speakers on surfaces that have been specially treated (for example, with wax, oil, polish) as staining or discoloration of the surface may result.
• If the system is brought directly from a cold to a warm location or is placed in a very damp room, moisture may condense on the lens inside the unit, and cause the system to malfunction. In this situation, remove the disc, and leave the system turned on for about an hour until the moisture evaporates.
On heat buildup
• Heat buildup on the unit during operation is normal and is not a cause for alarm.
• Do not touch the cabinet if it has been used continuously at a high volume because the cabinet may have become hot.
• Do not obstruct the ventilation holes.
On the speaker system
This speaker system is not magnetically shielded, and the picture on nearby TV sets may become magnetically distorte d. In this situation, turn off the TV, wait 15 to 30 minutes, and turn it back on. If there is no improvement, move the speakers far away from the TV.
Cleaning the cabinet
Clean this system with a soft cloth slightly moistened with a mild detergent solution. Do not use any type of abrasive pad, scouring powder, or solvent, such as thinner, benzine, or alcohol.
