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

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

Use the buttons on the unit for this
operation.

1 Select the AM band, and then turn

off the system.

2 While holding down ENTER, press

"/1.

The system turns on automatically and
“AM 9K STEP” or “AM 10K STEP”
appears.
All the AM preset stations are erased.
To reset the interval to the factory
preset, repeat the procedure.

To reset the system to factory
settings

If the system still does not operate
properly, reset the system to factory
settings. You cannot reset the system to
factory settings in Power Saving Mode.

1 Disconnect and reconnect the

power cord, and then turn on the
system.

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.
