- New Test Mode(aging operation and setup analysis)

The single CD player plays in normal mode. After being set up, it will display FOK (focus), LOCK (spindle), subcode,
sound skip, protection against a mechanical error or the like, occurrence of an error, cause and time of an expiry, if
any, (and disc number)
During the setup, the CD software operation status (internal RAM and C-point)is displayed.

(1) How to enter NEW TEST Mode

→Defects, disc upside-down, severe vibration

12 ELECTRIC SETUP failure Spindle failed to lock or subcode unreadable

Subcode failure →Spindle defective, defect, severe vibration

14 ELECTRIC Mirror failure Unrecorded CD-R

The disc is upside-down, defects, vibration

17 ELECTRIC Set up failure AGC protect failed

→Defects, disc upside-down, severe vibration

19 ELECTRIC Set up failure Tracking error waveform is too unbalanced (>50%) or

level is too small
→The pickup unit or tracking error circuitry is N.G.

30 ELECTRIC Search time out Failed to reach target address

→Carriage/tracking defective and/or defects

A0 SYSTEM Power failure Power overvoltage or short circuit detected

To Listen to Music

The following explains the initial operations required before you can listen to music.

Note:

• Loading a cassette in this product.

1. Select the desired source. (e.g. Tuner)

7 Head Unit

Each press of the SOURCE/OFF button selects the desired source in the following order:

CD player (one disc only) = Tuner = Tape = Multi-CD player = External Unit

= AUX

7 Remote Controller

Each press of the button selects the desired source in the following order:

TUNER button: Tuner = OFF

TAPE button : Tape = AUX = OFF

CD button : CD player (one disc only) = Multi-CD player = OFF

Note:

• External Unit refers to a Pioneer product (such as one available in the future) that, although incom-

patible as a source, enables control of basic functions by this product. Only one External Unit can

be controlled by this product.

• In the following cases, the sound source will not change:

* When a product corresponding to each source is not connected to this product.

* When no tape is set in this product.

* When no magazine is set in the Multi-CD player.

* When the AUX (external input) is set to OFF.

• When this product’s blue/white lead is connected to the car’s Auto-antenna relay control terminal,

the car’s Auto-antenna extends when this product’s source is switched ON. To retract the antenna,

switch the source OFF.

2. Extend the VOLUME forward.

When you press the VOLUME, it extends forward so that it becomes easier to roll. To

retract the VOLUME, press it again.

Each press changes the Source ...

3. Raise or lower the volume.

Rolling the VOLUME changes the volume level.

Note:

• Roll clockwise to raise the volume level.

• Roll counterclockwise to lower the volume level.

4. Turn the source OFF.

Hold for 1 second

Basic Operation of Cassette Player

Note:

• Be sure to close the front panel after loading or ejecting a cassette.

Cassette Loading Slot

Play Time Indicator

Note:

• The continuous playback time count starts at 00’00” at

the following times.

* When a tape is inserted.

* When the tape direction is changed.

* When you rewind the tape side currently playing

back to the beginning.

• The continuous playback time count is halted when

fast-forwarding/rewinding and while the Music Search

function is operating.

Eject

Note:

• The Tape function can be

turned ON/OFF with the cas-

sette tape remaining in this

product.

Note:

• “METAL” appears on the display for 4 seconds

when a metal or chrome tape is inserted. Nothing

is displayed for a normal tape.

Open

Note:

• Use to open the front panel when loading or ejecting a cassette.

(The illustration on the right shows the front panel open.)

Fast Forward/Rewind and Music Search

• Each press of the 3 button selects Fast Forward or Forward-Music

Search.

FF (Fast Forward) = F-MS (Forward-Music Search) = Normal Playback

• Each press of the 2 button selects Rewind or Rewind-Music

Search.

REW (Rewind) = R-MS (Rewind-Music Search) = Normal Playback

Note:

• Fast Forward/Rewind and Music Search can be canceled by pressing the BAND button.

Direction Change

Basic Operation of Tuner

Manual and Seek Tuning

• You can select the tuning method by changing the length of

time you press the 2/3 button.

Manual Tuning (step by step) 0.5 seconds or less

Seek Tuning 0.5 seconds or more

Note:

• If you continue pressing the button for longer than 0.5 seconds, you can skip

broadcasting stations. Seek Tuning starts as soon as you release the button.

• Stereo indicator “” lights when a stereo station is selected.

Preset Tuning

• You can memorize broadcast stations in buttons

1 through 6 for easy, one-touch station recall.

Preset station recall 2 seconds or less

Broadcast station preset memory 2 seconds or more

Note:

• Up to 18 FM stations (6 in F1 (FM1), F2 (FM2) and F3

(FM3)) and 6 AM stations can be stored in memory.

• You can also use the 5 or ∞ buttons to recall broadcast sta-

tions memorized in buttons 1 through 6.

Preset Number Indicator

Basic Operation of Multi-CD Player

This product can control a Multi-CD player (sold separately).

Track Search and Fast Forward/Reverse

• You can select between Track Search or Fast

Forward/Reverse by pressing the 2/3 button

for a different length of time.

Track Search 0.5 seconds or less

Fast Forward/Reverse Continue pressing

Play Time Indicator

Disc Search

Disc Number Indicator

Disc Number Search (for 6-Disc, 12-Disc types)

• You can select discs directly with the 1 to 6 buttons. Just press the num-

ber corresponding to the disc you want to listen to.

Note:

• When a 12-Disc Multi-CD Player is connected and you want to select disc 7 to 12, press the
