RDS (XR-5890R/5880R only)
Overview of the RDS
function
Radio Data System (RDS) is a broadcasting
service that allows FM stations to send
additional digital information along with the
regular radio programme signal. Your car
stereo offers you a variety of services. Here are
just a few: retuning the same programme
automatically, listening to traffic
announcements, and locating a station by
programme type.
Notes
• Depending on the country or region, not all of
the RDS functions are available.
• RDS may not work properly if the signal strength
is weak or if the station you are tuned to is not
transmitting RDS data.
Displaying the station
name
The name of the current station lights up in the
display.
Select an FM station (page 7).
When you tune in an FM station that
transmits RDS data, the station name
appears in the display.
Note
The “*” indication means that an RDS station is
being received.

will automatically change to the Motion
Display mode after a few seconds.
In the Motion Display mode, all the above
items are scrolled in the display one by one in
order.
Tip
The Motion Display mode can be turned off. (See
“Changing the sound and display settings” on
page 17).
Note
“NO NAME” appears if the received station does
not transmit RDS data (XR-5890R/5880R only).

11
Changing the display item
Each time you press (AF/TA), the item changes
as follows:
” TA-ON ”AF TA-ON*
AF-ON “AF TA-OFF “
*Select this to turn on both the AF and TA
functions.
Notes
• When “NO AF” and the station name flash
alternately, it means that the unit cannot find an
alternative station in the network.
• If the station name starts flashing after selecting
a station with the AF function on, this indicates
that no alternative frequency is available. Push
the SEEK/AMS control up or down while the
station name is flashing (within eight seconds).
The unit starts searching for another frequency
with the same PI (Programme Identification) data
(“PI SEEK” appears and no sound is heard). If the
unit cannot find another frequency, “NO PI”
appears, and the unit returns to the previously
selected frequency.
Listening to a regional programme
The “REG-ON” (regional on) function lets you
stay tuned to a regional programme without
being switched to another regional station.
(Note that you must turn the AF function on.)
The unit is factory preset to “REG-ON,” but if
you want to turn off the function, do the
following.

thenpress (3) (PLAY MODE)repeatedly
until“REG”appears.
2Press (4) (n)repeatedlyuntil“REG-OFF”

2Press (AF/TA) fortwoseconds.
”TA“ appears and the setting is stored.
Receiving emergency
announcements
If an emergency announcement comes in while
you are listening to the radio, the programme
will automatically switch to it. If you are
listening to a source other than the radio, the
emergency announcements will be heard if
you set AF or TA to on. The unit will then
automatically switch to these announcements
no matter which source you are listening to at
the time.
Presetting the RDS
stations with the AF and
TA data
When you preset RDS stations, the unit stores
each station’s data as well as its frequency, so
you don’t have to turn on the AF or TA
function every time you tune in the preset
station. You can select a different setting (AF,
TA, or both) for individual preset stations, or
the same setting for all preset stations.
Listening to traffic
announcements
The Traffic Announcement (TA) and Traffic
Programme (TP) data let you automatically
tune in an FM station that is broadcasting
traffic announcements even if you are listening
to other programme sources.
Press (AF/TA) repeatedlyuntil“TA-ON”
or“AFTA-ON”appears.
The unit starts searching for traffic
information stations. “TP” appears in the
display when the unit finds a station
broadcasting traffic announcements.
When the traffic announcement starts,
“TA” flashes. The flashing stops when the
traffic announcement is over.
Tip
If the traffic announcement starts while you are
listening to another programme source, the unit
automatically switches to the announcement and
goes back to the original source when the
announcement is over.
Notes
•
“NO TP” flashes for five seconds if the received
station does not broadcast traffic announcements.
Then, the unit starts searching for a station that
broadcasts it.

Additional
Information
Precautions
•If your car was parked in direct sunlight
resulting in a considerable rise in
temperature inside the car, allow the unit to
cool off before operating it.
•If no power is being supplied to the unit,
check the connections first. If everything is in
order, check the fuse.
•If no sound comes from the speakers of a
two-speaker system, set the fader control to
the centre position.
•When the tape is played back for a long
period, the cassette may become warm
because of the built-in power amplifier.
However, this is not a sign of malfunction.
If you have any questions or problems
concerning your unit that are not covered in
this manual, please consult your nearest Sony
dealer.
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 car audio. Sugary
residues on this unit or cassette tapes may
contaminate the playback heads, reduce the
sound quality, or prevent sound reproduction
altogether.
Cassette cleaning kits cannot remove sugar
from the tape heads.
Boosting the bass sound
— D-bass
You can enjoy a clear and powerful bass
sound. The D-bass function boosts the low
frequency signal with a sharper curve than
conventional bass boost.
You can hear the bass line more clearly even
while the vocal volume remains the same. You

•Do not touch the tape surface of a cassette, as
any dirt or dust will contaminate the heads.
•Keep cassettes away from equipment with
built-in magnets such as speakers and
amplifiers, as erasure or distortion on the
recorded tape could occur.
•Do not expose cassettes to direct sunlight,
extremely cold temperatures, or moisture.
•Slack in the tape may cause the tape to be
caught in the machine. Before you insert the
tape, use a pencil or similar object to turn the
reel and take up any slack.
•Distorted cassettes and loose labels can cause
problems when inserting or ejecting tapes.
Remove or replace loose labels.
•The sound may become distorted while
playing the cassette. The cassette player head
should be cleaned after each 50 hours of use.
Cassetteslongerthan90minutes
The use of cassettes longer than 90 minutes is
not recommended except for long continuous
play. The tape used for these cassettes is very
thin and tends to stretch easily. Frequent
playing and stopping of these tapes may cause
them to become entangled in the cassette deck
mechanism.

Maintenance
Fuse replacement
When replacing the fuse, be sure to use one
matching the amperage rating stated on the
original fuse. If the fuse blows, check the
power connection and replace the fuse. If the
fuse blows again after replacement, there may
be an internal malfunction. In such a case,
consult your nearest Sony dealer.
Warning
Never use a fuse with an amperage rating
exceeding the one supplied with the unit as
this could damage the unit.

Cleaning the connectors
The unit may not function properly if the
connectors between the unit and the front
panel are not clean. In order to prevent this,
open the front panel by pressing (RELEASE),
then detach it and clean the connectors with a
cotton swab dipped in alcohol. Do not apply
too much force. Otherwise, the connectors may
be damaged.
