Features

General

• Built-in power amplifier (max. output: 20W × 4ch ) enables you to connect to 4-speaker systems.
  Automatic loudness control automatically boosts high and low frequencies at low listening volumes for improved sound.

Cassette player section

• Auto-reverse cassette player provides continuous play of the cassette tape.
• Locking Fast-Forward and Rewind buttons let you easily move to any position on the tape.

Tuner section

• Up to 24 stations can be preset: 12 stations on FM, 6 stations on MW and 6 stations on LW.
• Seek tuning provides an easy way to find the station you want to listen to.
• Scan function scans each of the stations with the strongest signals for five seconds in order (page 5).
  Automatic Memory function stores a total of 24 stations in memory quickly and easily (page 6).
• Memory Scan function scans each preset station for five seconds in order (page 7).

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 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.
• When the tape is played back for a long period, the cassette shell may become warm because of the built-in power amplifier. However, this is not a sign of a malfunction.

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.

Removing the Unit

To prevent the unit from being stolen

When you leave your car, remove the unit from the bracket and take it away with you. Be sure to turn off the power of the unit before removing the unit, otherwise you may hear a noise.

The stations with the strongest signals will be scanned for five seconds each in order. Press the button again when the desired station is received.

Memorizing Stations

Memorizing Stations Automatically

Automatic Memory Function

This function selects from the currently received band six stations and memorizes them in order of their frequencies. If six strong stations cannot be found, it will search the band again looking for farther stations.

1 Select the desired band.

2 Use any tuning method to tune to a frequency slightly below that of the first station you want to memorize.
3 Press the M.SCAN/A.MEM button for more than two seconds.

Note

If a station you want to store has a weak signal or interference, it might not automatically be memorized.

Memorizing Only the Desired Stations

1 Select the desired band.

2 Tune in the station which you wish to store on the preset number button.
3 Keep the desired preset number button (1 to 6) pressed for about two seconds until the volume briefly mutes.

The number of the pressed preset number button now appears on the display window.

Up to 6 stations on each band (FM1, FM2, MW and LW) can be stored on the preset number buttons in order of your choice. Therefore, 12 stations can be memorized on FM. If you try to store another station on the same preset number button, the previously stored station will be erased.

Receiving the Memorized Stations

1 Select the desired band.

2 Press momentarily the preset number button on which the desired station is stored.

Note

If you press the preset number button for more than two seconds, the currently received station will be memorized. To receive the previously memorized station, make sure that the preset number button is pressed only momentarily.

Checking What is Being Broadcast on the Preset Stations — Memory Scan Function

1 Select the desired band.

2 Press the M.SCAN/A.MEM button momentarily.

The memorized stations will be scanned for five seconds each in order. (When the broadcast signal of a memorized station is too weak, it cannot be received.)

Note

Make sure that you press the M.SCAN/A.MEM button momentarily. If you press it for more than two seconds, the button will function as the A.MEM (automatic memory) button, and the memories of the currently activated preset number button and of the succeeding preset number buttons will be altered.

Maintenance

Fuse Replacement

When replacing the fuse, be sure to use one with the correct amperage which is stated on the fuse case. Never use a fuse whose amperage rating exceeds the one supplied to the unit, as this could cause a malfunction of the unit.

Warning

Use a fuse with the specified amperage. Use of a fuse with higher amperage may cause serious damage.

Cleaning the Head and the Tape Path

Prolonged use may contaminate the tape head and the tape path. Contamination causes sound drop-outs during playback.

Clean the tape head and the tape path every two weeks to enjoy optimum hi-fi stereo sound. Use a commercially available cleaning cassette.
