Attach part A of the front panel to part B of the unit as illustrated and push until it clicks.
Reset button Note Pressing the reset button will erase all the memorized program and memory functions.
Detaching the front panel
The front panel of this unit can be detached to prevent the unit from being stolen.
Notes Make sure the front panel is right side up when attaching it to the unit as it cannot be attached upside down. Do not press the front panel too hard when attaching it to the unit. It can easily be attached by pressing it lightly against the unit. When you carry the front panel with you, keep it in the supplied front panel case. Do not press hard or put excessive pressure on the display windows of the front panel. Do not expose the front panel to direct sunlight, heat sources such as hot air ducts or leave it in a humid place. Never leave it on the dashboard etc. of a car parked in direct sunlight where there may be a considerable rise in temperature inside the car.

Caution alarm

If you turn the ignition key to the OFF position without removing the front panel, the caution alarm will beep for a few seconds (only when the POWER SELECT switch is set to the A position).

Memorizing stations automatically

Best Tuning Memory (BTM)

This function selects from the currently received band the stations with the strongest signals and memorizes them in order of their frequency. PREVENTING ACCIDENTS! When tuning in while driving, use the automatic tuning or memory preset search function instead of manual tuning.
Memorizing only the desired stations
Up to 6 stations on each band (FM1, FM2, FM3, AM1 and AM2) can be stored on the preset number buttons in the order of your choice. Therefore, 18 FM stations can be memorized. If you try to store another station on the same preset number button, the most recently stored station will be erased.
Press (SOURCE) repeatedly to select the tuner. Press (MODE) repeatedly to select the band. Press (SEEK/AMS) to search for the station you wish to store on a preset number button.
Press (SOURCE) repeatedly to select the tuner. Each time you press (SOURCE), the source changes as follows:
TAPE n TUNER n MD/CD (XR-C5100 only)
Press the desired preset number button ((1) to (6)) for two seconds. Cassette Player/Radio
Press (MODE) repeatedly to select the band. Each time you press (MODE), the band changes as follows:
FM1 n FM2 n FM3 n AM1 n AM2
The number of the selected preset number button appears on the display.
Press (BTM) for two seconds.

If you cannot tune in a preset station
Press either side of (SEEK/AMS) momentarily to search for the station (automatic tuning). Scanning stops when a station is received. Press either side of (SEEK/AMS) repeatedly until the desired station is received.
Note If the automatic tuning stops too frequently, press (LCL) to light up LCL on the display (local seek mode). Only the stations with relatively strong signals are tuned in. Tip If you know the frequency, press and hold either side of (SEEK/AMS) until the desired station is received (manual tuning).
Adjust within three seconds after selecting. (After three seconds the button will again serve as the volume control button.)

Attenuating the sound

Press (ATT). The ATT indication flashes. To restore the previous volume level, press again.
Changing the sound and beep tone

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 2-speaker system, set the fader control to the center 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.

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.
MD/CD Unit/Additional Information
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.
Cassettes longer than 90 minutes The use of cassettes longer than 90 minutes is not recommended except for long continuous play. The tapes used for these cassettes are very thin and tend to be stretched easily. Frequent playing and stopping of these tapes may cause them to be pulled into 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.

Dismounting the unit

Release key (supplied)

Fuse (10 A)

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.
The rotary commander labels
You can control this unit with the optional rotary commander (RM-X4S). Some labels are supplied with the rotary commander. Attach that label that matches the functions of the master unit and the mounting position of the rotary commander. When you mount the rotary commander, attach the appropriate label, as in the illustration below.

Troubleshooting guide

The following checklist will assist in the correction of most problems you may encounter with your unit. Before going through the checklist below, refer to the operating procedures.
Problem No sound. Cause/Solution Adjust the volume with (+). Set the fader control to the center position for 2-speaker systems. Remove the front panel and clean the connectors. See Cleaning the Connectors in Maintenance for details. An optional power amplifier is connected to the LINE OUT and you are not using the built-in amplifier. The beep tone is attenuated.
Indications do not appear on the display. No beep tone.

Tape playback

Problem Playback sound is distorted. The AMS does not operate correctly. Cause/Solution Contamination of the tape head. n Clean the head. There is noise in the space between tracks. A blank space is too short (less than four seconds). + on (SEEK/AMS) is pressed immediately before the following track. = on (SEEK/AMS) is pressed 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.

Radio reception

Problem Preset tuning is not possible. Automatic tuning is not possible. Cause/Solution Store the correct frequency. The broadcast is too weak. The broadcast is too weak. n Use manual tuning.
Disc play (XR-C5100 only)
Problem Playback sound skips. Cause/Solution A dusty or defective disc.
