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 the right way up when attaching it to the unit as it cannot be attached upside down. Do not press the front panel hard against the unit 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, put it in the supplied front panel case. Do not press hard or give excessive pressure to 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.

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.

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.
If you have any questions or problems concerning your unit that are not covered in this manual, please consult your nearest Sony dealer.
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. 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 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 remote labels

You can control this unit with the optional rotary remote (RM-X2S). Some labels are supplied with the rotary remote. Attach that label which matches the functions of the master unit and the mounting position of the rotary remote. When you mount the rotary remote, attach the label 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 centre 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 and you are not using the built-in amplifier. The beep tone is muted (page 10).
Indications do not appear on the display window. 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. The ST indication flashes. Cause/Solution Store the correct frequency. The broadcast is too weak. The broadcast is too weak. n Use manual tuning. Tune in precisely. The broadcast is too weak.

Disc play

Problem Playback sound skips. Cannot turn off -------- indication Cause/Solution A dusty or defective disc. You cannot label MDs unless you connect a CD changer with the custom file function. n Press (FILE) for two seconds.
