Notes on the control and power supply leads The power antenna (aerial) control lead (blue) supplies +12 V DC when you turn on the tuner. When your car has built-in FM/AM antenna (aerial) in the rear/ side glass, connect the power antenna (aerial) control lead (blue) or the accessory power supply lead (red) to the power terminal of the existing antenna (aerial) booster. For details, consult your dealer. A power antenna (aerial) without a relay box cannot be used with this unit. Memory hold connection When the yellow power supply lead is connected, power will always be supplied to the memory circuit even when the ignition switch is turned off. Notes on speaker connection Before connecting the speakers, turn the unit off. Use speakers with an impedance of 4 to 8 ohms, and with adequate power handling capacities to avoid its damage. Do not connect the speaker terminals to the car chassis, or connect the terminals of the right speakers with those of the left speaker. Do not connect the ground (earth) lead of this unit to the negative () terminal of the speaker. Do not attempt to connect the speakers in parallel. Connect only passive speakers. Connecting active speakers (with built-in ampliers) to the speaker terminals may damage the unit. To avoid a malfunction, do not use the built-in speaker leads installed in your car if the unit shares a common negative () lead for the right and left speakers. Do not connect the units speaker leads to each other. Note on connection If speaker and amplier are not connected correctly, FAILURE appears in the display. In this case, make sure the speaker and amplier are connected correctly.

CAUTION

The use of optical instruments with this product will increase eye hazard.

About MP3 files

MP3, which stands for MPEG-1 Audio Layer-3, is a music file compression format standard. It compresses audio CD data to approximately 1/10 of its original size. ID3 tag versions 1.0, 1.1, 2.2, 2.3 and 2.4 apply to MP3 only. ID3 tag is 15/30 characters (1.0 and 1.1), or 63/126 characters (2.2, 2.3 and 2.4). When naming an MP3 file, be sure to add the file extension.mp3 to the file name. During playback or fast-forward/reverse of a VBR (Variable Bit Rate) MP3 file, elapsed playing time may not display accurately.
Note If you play a high-bit-rate MP3, such as 320 kbps, sound may be intermittent.

About WMA files
WMA, which stands for Windows Media Audio, is a music file compression format standard. It compresses audio CD data to approximately 1/22* of its original size. WMA tag is 63 characters. When naming a WMA file, be sure to add the file extension.wma to the file name. During playback or fast-forward/reverse of a VBR (Variable Bit Rate) WMA file, elapsed playing time may not display accurately.

Troubleshooting

The following checklist will help you remedy problems you may encounter with your unit. Before going through the checklist below, check the connection and operating procedures.

Radio reception

The stations cannot be received. The sound is hampered by noises. The connection is not correct. t Connect a power antenna (aerial) control lead (blue) or accessory power supply lead (red) to the power supply lead of a cars antenna (aerial) booster (only when your car has built-in FM/AM antenna (aerial) in the rear/side glass). t Check the connection of the car antenna (aerial). t If the auto antenna (aerial) will not go up, check the connection of the power antenna (aerial) control lead. Preset tuning is not possible. Store the correct frequency in the memory. The broadcast signal is too weak. Automatic tuning is not possible. Setting of the local seek mode is not correct. t Tuning stops too frequently: Set LOCAL-ON (page 10). t Tuning does not stop at a station: Set LOCAL-OFF (page 10). The broadcast signal is too weak. t Perform manual tuning. During FM reception, the ST indication flashes. Tune in the frequency accurately. The broadcast signal is too weak. t Set MONO-ON (page 10). An FM program broadcast in stereo is heard in monaural. The unit is in monaural reception mode. t Set MONO-OFF (page 10).

No power is being supplied to the unit. Check the connection or fuse. If the unit is turned off and the display disappears, it cannot be operated with the remote commander. t Turn on the unit. The power antenna (aerial) does not extend. The power antenna (aerial) does not have a relay box. No sound. The ATT function is activated. The position of the fader control FAD is not set for a 2-speaker system. No beep sound. The beep sound is canceled (page 10). An optional power amplifier is connected and you are not using the built-in amplifier. The contents of the memory have been erased. The RESET button has been pressed.*1 t Store again into the memory. The power supply lead or battery has been disconnected or it is not connected properly. Stored stations and correct time are erased. The fuse has blown. Makes noise when the position of the ignition is switched. The leads are not matched correctly with the cars accessory power connector. During playback or reception, demonstration mode starts. If no operation is performed for 5 minutes with DEMO-ON set, demonstration mode starts. t Set DEMO-OFF (page 10). The display disappears from/does not appear in the display window. The dimmer is set DIM-ON (page 10). The display disappears if you press and hold (SOURCE/OFF). t Press (SOURCE/OFF) on the unit until the display appears. The connectors are dirty (page 14). The Auto Off function does not operate. The unit is turned on. The Auto Off function activates after turning off the unit. t Turn off the unit.
PTY displays - - - - - - - -. The current station is not an RDS station. RDS data has not been received. The station does not specify the program type.

CD playback

The disc cannot be loaded. Another disc is already loaded. The disc has been forcibly inserted upside down or in the wrong way. The disc does not playback. Defective or dirty disc. The CD-Rs/CD-RWs are not for audio use (page 12). MP3/WMA files cannot be played back. The disc is incompatible with the MP3/WMA format and version (page 13).
