Frequently Asked Questions - CDX-U8000 SONY

How do I install the CDX-U8000 in my car?

Ensure the car battery is disconnected. Use the supplied mounting sleeve and trim ring. Connect the wiring harness according to the color codes: yellow for constant 12V, red for switched 12V, black for ground, and speaker wires. Slide the unit into the sleeve until it clicks.

Why won't the CD play?

First, check if the CD is inserted correctly with the label facing up. Ensure the disc is not scratched or dirty. If the unit displays 'ERROR' or 'NO DISC', try cleaning the disc with a soft cloth. If the problem persists, reset the unit by pressing the reset button with a pointed object.

How do I set the clock on the CDX-U8000?

Press and hold the DSPL (Display) button until the hour digits flash. Rotate the volume control knob to set the hour, then press the button again. The minute digits will flash. Rotate to set minutes, then press the button to confirm.

How can I adjust the sound settings like bass and treble?

Press the SOUND button repeatedly to cycle through EQ presets or to access manual settings: Bass, Treble, Balance, Fader, and Loudness. Use the volume knob to adjust each setting. Press SOUND again to save.

How do I use the remote control?

Point the remote at the unit's sensor. Use the VOL +/ - for volume, SEEK/AMS for track or station search, MODE to switch sources, and DSPL to change display. The remote requires a CR2025 battery.

What should I do if FM/AM radio reception is poor?

Check the antenna connection. For FM, ensure the antenna is fully extended. If reception is still weak, try manual tuning to fine-tune stations. In some areas, a signal booster may be needed. Also, avoid parking near large metal structures.

Can I connect an external device like a phone or MP3 player?

Yes, the CDX-U8000 has a front Aux input (3.5mm mini-jack). Connect your device with a standard audio cable. Press the MODE button repeatedly until 'AUX' appears on the display. Adjust volume on both the unit and your device.

How do I reset the unit to factory settings?

Use a pointed object like a pen to press the RESET button located behind the detachable faceplate (near the disc slot). This will clear all settings and memory, restoring factory defaults.

How do I clean the CD lens?

Purchase a CD lens cleaning disc from an electronics store. Insert the cleaning disc and play it according to the instructions. Never use liquid cleaners directly on the lens, as they may damage the optical pickup.

Does the CDX-U8000 support MP3 and WMA files?

Yes, it plays MP3 and WMA files burned on CD-R or CD-RW discs. Ensure the files are saved at a bitrate of 32-320 kbps for MP3 and 32-192 kbps for WMA. The unit can read up to 255 folders and 512 files on a disc.

Whatever the display mode is, the indication automatically changes as follows:

Memorizing the Stations Automatically

—BTM (Best Tuning Memory) Function

Best receiving stations are automatically searched and memorized on each band (FM1, FM2 and AM). Up to 10 stations on each band can be stored on the preset number buttons 1 to 10 in the order of frequency.

1 Select the desired band from FM1, FM2 or AM. The band changes in the following order: FM1 → FM2 → AM.

2 Keep the BTM button pressed for more than two seconds.

Checking in Order, All the Stations Stored in the Memory—Memory Scan Function

Press lightly.

The tuner will receive in order, all the stations stored in the memory for five seconds each.

To cancel

Press the M. SCAN button lightly once more. The memory scan will be canceled and you will be able to listen to the station currently being received.

The receivable frequencies of FM1 and FM2 are the same

Therefore, 20 stations can be memorized on FM.

Note

There may be cases where even the stations which are stored in the memory cannot be received due to weak signals in the vicinity of your car.

The BTM function — how this function operates

This function starts by searching stations from the lowest frequency of the currently tuned in band. When a station is located, it will be stored in the memory on the preset button whose number is indicated on the display window. If there is no preset number indicated, it will be stored in the memory on the preset number button 1 onward. It continues to store the stations in the memory until all the preset buttons are occupied.

For example, if the FM1 band was selected, it will continue until the preset button 10 on the FM2 band is occupied. When all the memory preset buttons are occupied with the memories before the highest receivable frequency is searched, the unit will start searching for higher frequencies from where it was left off. This is to check if there are any more stations with better receptions than the ones already stored in the memory.

If a station with a better reception is found, the unit will store it in the memory in place of a station with an inferior reception.

Lastly, it rearranges all the stations in the order of frequency from the lowest and stores them in the memory. The whole operations is now completed. The stations with better receptions are stored in the memory on the preset number buttons in the order of frequency.

Notes

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

- If you start the BTM operation from the FM1 band, it will continue to store stations in the memory on the FM2 band. Care must be taken if you wish to keep the stored stations on the FM2 band

- If you start the BTM operation from the FM2 band, it will stop when all the memories on the FM2 band are occupied. It will not continue to the FM1 band

Memorizing Only the Desired Stations

Up to 10 stations on each band (FM1, FM2 and AM) can be stored on the preset number buttons in order of your choice (a total of 30 stations).

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

1 Select a desired band from FM1, FM2 or AM.

The band changes in the following order: FM1 → FM2 → AM.

2 Tune in the station which you wish to store on the preset number button. (page 32 or 34)

3 Keep the preset number button pressed for about two seconds until the "MEM" indication comes on the display window.

The number of the preset number button of which you are pressing now comes on the display window. When the "MEM" indication comes on, the station is stored in the memory and the operation is now completed. The "MEM" indication goes off after a while.

Repeat the same procedure to store other stations.

Only one station per band (FM1, FM2 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 Stations Stored in the Memory

1 Select the desired band from FM1, FM2 or AM. The band changes in the following order: FM1 → FM2 → AM.

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

Précautions

When the Unit Is Used in a Car with No Accessory Position on the Ignition Key — POWER SELECT switch

The illumination on the front panel is factory-set to be turned on even when the unit is not being played. However, this setting may cause some car battery wear if the unit is used in a car with no accessory position on the ignition key.

To avoid this battery wear when using the unit in such a car, set the POWER SELECT switch located at the bottom of the unit to the OFF position, then press the reset button. The illumination is reset to stay off while the unit is not being played.

Note

The caution alarm for the front panel is not activated when the POWER SELECT switch is set to the OFF position.

When an FM Diversity Antenna is Used — FM DIVERSITY switch

This unit can be connected with diversity antennas. If you use this unit with the diversity antennas, set the FM DIVERSITY switch located at the bottom of the unit to the ON position to activate the diversity system.

When you do not use the FM diversity antennas

If you wish to connect a conventional rod antenna, be sure to connect it to the antenna connector of the unit marked "MAIN", and set the FM DIVERSITY switch to the OFF position. Never connect the antenna to the connector marked "SUB", otherwise if the FM DIVERSITY switch is set to the ON position, the radio signals may not be received properly.

Note

The radio reception will be disturbed by noise if the connection of the antennas was not made properly or the FM DIVERSITY switch was not set correctly.
