FM/MW/LW Cassette Car Stereo
Operating Instructions GB
For installation and connections, see the supplied installation/connections manual.
Thank you for purchasing this Sony Cassette Player. This unit lets you enjoy a variety of features using the following controller accessory:
Optional accessory
Rotary commander (RM-X4S)
XR-C33R only:
In addition to the cassette playback and radio operations, you can expand your system by connecting an optional CD/MD unit*1.
When you operate this unit or a connected optional CD unit with the CD TEXT function, the CD TEXT information will appear in the display when you play a CD TEXT disc*2.
1 You can connect a CD changer, an MD changer, a CD player, or an MD player.
2 A CD TEXT disc is an audio CD that includes information such as the disc name, artist name, and track names.
This information is recorded on the disc.
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.
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.

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.

- 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.

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 19).
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 long-distance drive without having to retune the station manually.

2 Press / TA repeatedly until "AF-ON" appears.

The unit starts searching for an alternative station with a stronger signal in the same network.
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.
Changing the display item
Each time you press / TA , the item changes as follows:

- 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.
1 During radio reception, press SHIFT, then press ③ (PLAY MODE) repeatedly until "REG" appears.

1 Press a number button that has a local station stored on it.
2 Within five seconds, press the number button of the local station again.
3 Repeat this procedure until the desired local station is received.
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.
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.
Preseting the volume of traffic announcements
You can preset the volume level of the traffic announcements beforehand so you won't miss the announcement. When a traffic announcement starts, the volume will be automatically adjusted to the preset level.
1 Select the desired volume level.
2 Press / 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 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.
Presetting the same setting for all preset stations
1 Select an FM band (page 9).
2 Press ( / 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.
3 Press SHIFT, then press 3 (PLAY MODE) repeatedly until "B.T.M" appears.
4 Press ④ () until "B.T.M" flashes.
5 Press SHIFT.
Presetting different settings for each preset station
1 Select an FM band, and tune in the desired station.
2 Press ( / TA) repeatedly to select either "AF-ON," "TA-ON" or "AF TA-ON" (for both AF and TA functions).
3 Press the desired number button and hold until "MEM" appears.
