• Use a disc with MP3/WMA tracks recorded in a format 

compliant with ISO 9660 Level 1, Level 2, Romeo, or Joliet.

• Add the extension code <.mp3> or <.wma> to the file 

names.

Noise is generated.

Skip to another track or change the disc. (Do not add the 
extension code <.mp3> or <.wma> to non-MP3 or WMA 
tracks.)

A longer readout time is required 
(“READING” keeps flashing on the 
display).

Do not use too many hierarchical levels and folders. 

Tracks are not played back in the order 
you have intended.

Playback order is determined when the files are recorded.

The elapsed playing time is not correct. This sometimes occurs during playback. This is caused by 

how the tracks are recorded on the disc.

The correct characters are not 
displayed (e.g. album name).

This unit can only display letters (upper case), numbers, and 
a limited number of symbols.

The fuse blows.

Connect the red and black leads correctly.

Power cannot be turned on.

Check to make sure the yellow lead is connected.

No sound from the speakers.

Check to make sure the speaker output lead is not 
shortcircuited.

Sound is distorted.

• Check to make sure the speaker output lead is grounded.
• Check to make sure the “–” terminals of L and R speakers 

are grounded in common.

Noise interfere with sounds.

Check to make sure the rear ground terminal connected to 
the car’s chassis is using shorter and thicker cords.

This unit becomes hot.

• Check to make sure the speaker output lead is grounded.
• Check to make sure the “–” terminals of L and R speakers 

are grounded in common.

This unit does not work at all.

Reset the unit. (See page 1.)

• CD-RWs may require a longer readout time since 

the reflectance of CD-RWs is lower than that of 
regular CDs.

• This unit can play back MP3/WMA files with the 

extension code <.mp3> or <.wma> (regardless of 
the letter case—upper/lower).

• This unit can show the names of albums, artists

folders, and 8 hierarchical levels.

• This unit can play back files recorded in VBR 

(variable bit rate).

  Files recorded in VBR have a discrepancy in the 

elapsed time display, and do not show the actual 
elapsed time. In particular, this difference becomes 
noticeable after performing the search function.

• This unit cannot play back the following files:
  – MP3 files: encoded in MP3i and MP3 PRO format; 

an inappropriate format; layer 1/2.

playback stops. Next time you select “CD” as the 
playback source, playback will start from where it 
had been stopped previously.

• If the ejected disc is not removed within 

15 seconds, the disc is automatically inserted again 
into the loading slot to protect it from dust.
