• 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.
• As the laser beam used in this compact disc player is harmful to the eyes, do not attempt to disassemble the cabinet. Refer servicing to qualified personnel only.
• If your car is equipped with a power antenna, note that it will be automatically extended while the unit is being operated.

Note on moisture condensation

On a rainy day or in a very damp environment, moisture in the atmosphere may condense on the lenses inside the unit. Should this occur, the unit may not operate properly. In such a case, remove the disc from inside the car and wait for about an hour or so until the moisture has evaporated.

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

important

Since the CD system offers a wide dynamic range, the peaks of the high level inputs are recorded with high fidelity and the noise level is very low. Do not turn up the volume while listening to a section with no audio signals or very low level inputs. If you do so, the speakers may be damaged when a section with a peak signal is played.

Select the desired band, then press and hold either side of the SEEK/MANU button.

For lower frequencies

For higher frequencies

Release the button when the desired station is received.

At least two seconds after releasing the button, the system will return to Automatic Tuning.

PREVENTING ACCIDENTS!

While you are driving' the use of the Automatic Tuning and the Memory Preset Tuning is recommended instead of the Manual Tuning.

Note

Make sure that you press either side of the SEEK button lightly. If you keep it pressed, the button will function as the manual tuning button.

When an FM stereo program with a sufficient signal strength is tuned in

The "STEREO" indication will appear.

Avoiding the automatic tuning from stopping on stations too frequently (Local Seek Mode) Press the SENS button lightly to get the "LOCAL" indication. Only the stations with relatively strong signals can be tuned in. The local seek mode functions only when the Automatic Tuning is in operation.

Using the Memory Preset Function

Stations with clearest reception are automatically searched and memorized on each band (FMI).

FMII. FMIII and AM)

Up to 6 stations on each band can be stored on the preset number buttons 1 to 6 in the order of frequency.

1

Memorizing the Stations Automatically

— A.MEM (Auto Memory) Function

1 Select the desired band.

2 Press the A.MEM button for more than two seconds.

The A.MEM function

The A.MEM function searches all the receivable stations within the currently selected band and memorizes the ones in good receiving conditions in sequence from the frequency at present.

How to memorize the stations on the preset number buttons

— When there is no preset number indicated on the display window, all the preset number buttons set in the currently selected band will be filled with the memories.
— When there is a preset number indicated on the display window, the unit will memorize the stations on the preset number buttons from the one currently being displayed. For example, when you choose FMI and preset number 3 is being displayed, the operation will start from the preset number 3 on FMI and stops at the preset number 6 on FMI.

The receivable frequencies of FM1. FMII and FMIII are the same.

Therefore, 18 stations can be memorized on FM

Note

There may be cases where there are not enough receivable stations due to the lack of stations in the vicinity or weak broadcasting signals. In such cases, the A.MEM operation may stop without all the buttons being occupied with memories.

Memorizing Only the Desired Stations

For example, store a station on the preset number button 1.

Up to 6 stations on each band (FMI, FMII, FMIII and AM) can be stored in the memory in order of your choice.

Only one station per band (FMI, FMII, FMIII and AM) can be stored in the memory on each preset number button.

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 the desired preset number button lightly.

Notes

• There may be cases in which even the stations stored in the memory cannot be received due to weak signals in the vicinity of your car.
• If you keep pressing the preset number button for more than two seconds, the currently received station will be memorized. To receive the previously memorized station, press the preset number button only lightly.

Caution

• This unit is designed for negative ground 12 V DC operation only.
• Before making connections, disconnect the ground terminal of the car battery to avoid short circuits.
• Connect the red power input lead only after all other leads are connected. And be sure to connect it to the positive 12 V power terminal which is energized when the ignition key is set to the accessory position.
• Run all ground wires to a common ground point.

Précautions

Votes on speaker connections

- Use speakers with an impedance of 4 to 8 ohms, and with adequate power handling capacities.

Otherwise, the speakers may be damaged.

- Do not connect the terminals of the speaker system to the car chassis, and do not connect the terminals

of the right speaker with those of the left speaker.

• Do not connect the speakers in parallel.

Do not connect any active speakers (with built-in amplifiers) to the speaker terminals of the unit. Doing so may damage the active speakers. Therefore, be sure to connect passive speakers to these terminals.

Notes on the control leads

• A power antenna without relay box cannot be used with this unit.

The numbers in the list are keyed to those in the instructions.
