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.
Tip The Motion Display mode can be turned off. (See Changing the sound and display settings on page 16). Note NO NAME appears if the received station does not transmit RDS data.
Retuning the same programme automatically
Alternative Frequencies (AF)
The Alternative Frequencies (AF) function automatically selects and retunes the station with the strongest signal in a network. By using this function, you can continuously listen to the same programme during a longdistance drive without having to retune the station manually.
Frequencies change automatically. 96.0MHz

98.5MHz

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.

Station

102.5MHz
Select an FM station (page 7). Press (AF/TA) repeatedly until AF-ON appears. The unit starts searching for an alternative station with a stronger signal in the same network.

Note The * indication means that an RDS station is being received.
Station Name (Frequency) Clock
Note When there is no alternative station in the area and you do not need to search for an alternative station, turn the AF function off by pressing (AF/TA) repeatedly until AF TA-OFF appears.
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.
Local link function (United Kingdom only)
The Local Link function lets you select other local stations in the area, even if they are not stored on your number buttons.
Press a number button that has a local station stored on it. Within five seconds, press the number button of the local station again. Repeat this procedure until the desired local station is received.
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.
During radio reception, press (SHIFT), then press (3) (PLAY MODE) repeatedly until REG appears. Press (4) (n) repeatedly until REG-OFF appears. Press (SHIFT). Note that selecting REG-OFF might cause the unit to switch to another regional station within the same network.
To return to regional on, select REG-ON in step 2 above.
Note This function does not work in the United Kingdom and in some other areas.
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) repeatedly until TA-ON or AF TA-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. When EON appears with TP in the display, the current station makes use of broadcast traffic announcements by other stations in the same network.

Presetting the volume of traffic announcements
You can preset the volume level of the traffic announcements beforehand so you wont miss the announcement. When a traffic announcement starts, the volume will be automatically adjusted to the preset level.
Select the desired volume level. Press (AF/TA) for two seconds. 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 stations data as well as its frequency, so you dont 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.
To cancel the current traffic announcement
Press (AF/TA) or (SOURCE). To cancel all traffic announcements, turn off the function by pressing (AF/TA) until AF TA-OFF appears.
Presetting the same setting for all preset stations
Select an FM band (page 7). Press (AF/TA) repeatedly to select either AF-ON, TA-ON or AF TA-ON (for both AF and TA functions). Note that selecting AF TA-OFF stores not only RDS stations, but also non-RDS stations. Press (SHIFT), then press (3) (PLAY MODE) repeatedly until B.T.M appears. Press (4) (n) until B.T.M flashes. Press (SHIFT).

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 a 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.

Notes on Cassettes

Cassette care 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.
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.

The sound may become distorted while playing the cassette. The cassette player head should be cleaned after each 50 hours of use. Cassettes longer than 90 minutes 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.

XR-C5120R/C5110R:

Notes For safety, turn off the engine before cleaning the connectors and remove the key from the ignition switch. Never touch the connectors directly with your fingers or any metal device.

Dismounting the unit

Release key (supplied) Fuse (10 A) XR-C4120:

Troubleshooting guide

The following checklist will help you remedy the problems you may encounter with your unit. Before going through the checklist below, check the connections and operating procedures.
Problem No sound. Cause/Solution Cancel the ATT function. Set the fader control to the centre position for two-speaker systems. Rotate the dial clockwise to adjust the volume. The power cord or battery has been disconnected. The reset button was pressed. n Store again into the memory. Remove the front panel and clean the connectors. See Cleaning the connectors (page 21) for details.
The contents of the memory have been erased. Indications do not appear in the display.

Tape playback

Problem The sound is distorted. Cause/Solution The tape head is contaminated. n Clean the head with a commercially available dry-type cleaning cassette. There is noise in the space between tracks. A blank space is too short (less than four seconds). The SEEK/AMS control was pushed up immediately before the following track. The SEEK/AMS control was pushed down immediately after the track starts. A long pause, or a passage of low frequencies or very low sound level is treated as a blank space.
The AMS does not operate correctly.

Radio reception

Problem Preset tuning is not possible. Automatic tuning is not possible. The ST indication flashes. Cause/Solution Memorize the correct frequency. The broadcast signal is too weak. The broadcast signal is too weak. n Use manual tuning. Tune in the frequency accurately. The broadcast signal is too weak. n Set to MONO mode (page 8).
