BASIC OPERATIONS

RELATED TO VOICE RECOGNITION

Related to Telephone

The system should respond correctly to all voice commands without difficulty. If problems are encountered, try
the following solutions.
Where the solutions are listed by number, try each solution in turn, starting with number 1, until the problem is
resolved.

RELATED TO AUDIO

• The majority of the audio malfunctions are the result of outside causes (bad CD/cassette, electromagnetic

interference, etc.). Check the symptoms below to diagnose the malfunction.

• The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning.

Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and oper-
ation of each piece of electrical equipment, and then determine the cause.

NOTE:
• CD-R is not guaranteed to play because they can contain compressed audio (MP3, WMA, AAC, M4A) or

could be incorrectly mastered by the customer on a computer.

• Check if the CDs carry the Compact Disc Logo. If not, the disc is not mastered to the “red book” Compact

Disc Standard and may not play.

Symptom

Possible cause

Possible solution

No image is displayed.

The brightness is at the lowest setting.

Adjust the brightness of the display.

The systems in the video mode.

Press “DISC-AUX” to change the mode.

The display is turned off.

Press “

OFF” to turn on the display.

The screen is too dim. The move-
ment is slow.

The temperature in the interior of the vehicle is low.

Wait until the interior of the vehicle has
warmed up.

Some pixels in the display are dark-
er or brighter than others.

This condition is an inherent characteristic of liquid
crystal displays.

This is not a malfunction.

Some menu items cannot be se-
lected.

Some menu items become unavailable while the ve-
hicle is driven.

Park the vehicle in a safe location, and
then operate the multi AV system.

Symptom

Solution

System fails to interpret the com-
mand correctly.

1. Ensure that the command is valid.

2. Ensure that the command is spoken after the tone.

3. Speak clearly without pausing between words and at level appropriate to the ambient noise lev-
el in the vehicle.

4. Ensure that the ambient noise level is not excessive (for example, windows open or defroster
on).
NOTE:
If it is too noisy to use the phone, it is likely that the voice commands will not be recognized.

5. If more than one command was said at a time, try saying the commands separately.

6. If the system consistently fails to recognize commands, the voice training procedure should be
carried out to improve the recognition response for the speaker. See “Speaker adaptation (SA)
mode” earlier in this section. Refer to “OWNER’S MANUAL”.

The system consistently selects
the wrong voicetag

1. Ensure that the phone book entry name requested matches what was originally stored. This
can be confirmed by using the “List Names” command.

2. Replace one of the names being confused with a new name.

Noise resulting from variations in field strength, such as fading noise and multi-path noise, or external noise from trains and other
sources, is not a malfunction.

NOTE:

• Fading noise: This noise occurs because of variations in the field strength in a narrow range due to mountains or buildings blocking

the signal.

• Multi-path noise: This noise results from a time difference between the broadcast waves directly from the station arriving at the

antenna and the waves reflected by mountains or buildings.

Symptom

Cause and Counter measure

Cannot play

Check if the CD was inserted correctly.

Check if the CD is scratched or dirty.

Check if there is condensation inside the player, and if there is, wait until the condensation is gone
(about 1 hour) before using the player.

If there is a temperature increase error, the player will play correctly after it returns to the normal
temperature.

If there is a mixture of music CD files (CD-DA data) and MP3/WMA/AAC/M4A files on a CD, only
the music CD files (CD-DA data) will be played.

Files with extensions other than “.MP3”, “.WMA”, “.AAC”, “M4A”, “.mp3”, “.wma”, “.aac” or “.m4a”
cannot be played. In addition, the character codes and number of characters for folder names and
file names should be in compliance with the specifications.

Check if the disc or the file is generated in an irregular format, This may occur depending on the
variation or the setting of MP3/WMA/AAC writing applications or other text editing applications.

Check if the finalization process, such as session close and disc close, is done for the disc.

Check if the CD is protected by copyright.

Discs recorded in live file system format are not supported. (For Microsoft Windows Vista, check
the settings.)

Poor sound quality

Check if the CD is scratched or dirty.

It takes a relatively long time before
the music starts playing.

If there are many folder or file levels on the MP3/WMA/AAC/M4A CD, or if it is a multisession disc,
some time may be required before the music starts playing.

Music cuts off or skips

The writing software and hardware combination might not match, or the writing speed, writing
depth, writing width might not match the specifications. Try using the slowest writing speed.

Skipping with high bit rate files

Skipping may occur with large quantities if data such as for high bit rate data.

Move immediately to the next song
when playing

When a non-MP3/WMA/AAC file has been given an extension of “.MP3”, “.WMA”, “.AAC”, “.M4A”,
“.mp3”, “.wma”, “.aac” or “.m4a” or when play is prohibited by copyright protection, the player will
skip to the next song.

The songs do not play back in the
desired order.

The playback order is the order in which the files were written by the software, so the files might
not play in the desired order.
