does not mean there is a problem with

your radio—it is just the normal result of

conditions outside the vehicle.

For example, nearby buildings and terrain

can interfere with FM reception. Power

lines or telephone wires can interfere with

AM signals. And of course, radio signals

have a limited range. The farther you are

from a station, the weaker its signal will

be. In addition, reception conditions

change constantly as your vehicle moves.

CAUTION

Operate the switches with due care

while you are driving to avoid acci-

dents.

Here are some common reception prob-

lems that probably do not indicate a prob-

lem with your radio:

AM

ꢀ Bumpy roads or other vibrations may

make your compact disc player skip.

Fading—AM broadcasts are reflected by

the upper atmosphere—especially at night.

These reflected signals can interfere with

those received directly from the radio sta-

tion, causing the radio station to sound

alternately strong and weak.

ꢀ If moisture gets into your compact disc

player, you may not hear any sound

even though your compact disc player

appears to be working. Remove the

disc from the player and wait until it

dries.

FM

Fading and drifting stations—Generally, the

effective range of FM is about 40 km (25

miles). Once outside this range, you may

notice fading and drifting, which increase

with the distance from the radio transmit-

ter. They are often accompanied by distor-

tion.

Station interference—When a reflected sig-

nal and a signal received directly from a

radio station are very nearly the same

frequency, they can interfere with each

other, making it difficult to hear the broad-

cast.

CAUTION

Compact disc players use an invisible

laser beam which could cause hazard-

ous radiation exposure if directed

outside the unit. Be sure to operate

the player correctly.

Multi−path—FM signals are reflective,

making it possible for two signals to reach

your antenna at the same time. If this

happens, the signals will cancel each oth-

Static—AM is easily affected by external

sources of electrical noise, such as high

tension power lines, lightening, or electri-

cal motors. This results in static.

a

momentary flutter or

Static and fluttering—These occur when

signals are blocked by buildings, trees, or

other large objects. Increasing the bass

level may reduce static and fluttering.

CARING FOR YOUR COMPACT DISC

PLAYER AND DISCS

ꢀ The player is intended for use with

12cm (4.7 in.) discs only.

Station swapping—If the FM signal you

are listening to is interrupted or weak-

ened, and there is another strong station

nearby on the FM band, your radio may

tune in the second station until the origi-

nal signal can be picked up again.

ꢀ Extremely high temperatures can keep

your compact disc player from working.

On hot days, use the air conditioning

to cool the vehicle interior before you

listen to a disc.

Special shaped discs

Low quality discs

ꢀ Use only compact discs marked as

shown above. The following products

may not be playable on your compact

disc player.

NOTICE

Do not use special shaped, transpar-

ent/translucent, low quality or labeled

discs such as those shown in the il-

lustrations. The use of such discs

may damage the player or changer, or

it may be impossible to eject the

disc.

Correct

Wrong

ꢀ Handle compact discs carefully, espe-

cially when you are inserting them.

Hold them on the edge and do not

bend them. Avoid getting fingerprints

on them, particularly on the shiny side.

To clean a compact disc: Wipe it with a

soft, lint−free cloth that has been damp-

ened with water. Wipe in a straight line

from the center to the edge of the disc

(not in circles). Dry it with another soft,

lint−free cloth. Do not use a conventional

record cleaner or anti−static device.

ꢀ Dirt, scratches, warping, pin holes, or

other disc damage could cause the

player to skip or to repeat a section of

a track. (To see a pin hole, hold the

disc up to the light.)

ꢀ Remove discs from the compact disc

player when you are not listening to

them. Store them in their plastic cases

away from moisture, heat, and direct

sunlight.

MP3 WMA FILES

ꢀ WMA files can contain a WMA tag that

is used in the same way as an ID3

tag. WMA tags carry information such

as track title, artist name.

ꢀ The MP3/WMA player does not play

back MP3/WMA files from discs record-

er using packet write data transfer

(UDF format). Discs should be re-

corded using “per−mastering” software

rather than packet−write software.

ꢀ MP3 (MPEG Audio Layer 3) and WMA

(Windows Media Audio) are audio com-

pression standards.

ꢀ The emphasis function is available only

when playing MP3/WMA files recorded

at 32, 44.1 and 48 kHz. (The system

can play MP3 files with sampling fre-

quencies of 16, 22.05, and 24 kHz.

However, the emphasis function is not

available for files recorded at these fre-

quencies.)

ꢀ The MP3/WMA player can play MP3

and WMA files on CD−ROM, CD−R and

CD−RW discs.

ꢀ M3u playlists are not compatible with

the audio player.

The unit can play disc recordings com-

patible with ISO 9660 level 1 and level

2 and with the Romeo and Joliet file

system.

ꢀ MP3i (MP3 interactive) and MP3PRO

formats are not compatible with the au-

dio player.

ꢀ The MP3 player is compatible with

ꢀ When naming an MP3 or WMA file,

add the appropriate file extension (.mp3

or .wma)

ꢀ The sound quality of MP3/WMA files

generally improves with higher bit

rates. In order to achieve a reasonable

level of sound quality, discs recorded

with a bit rate of at least 128 kbps are

recommended.

VBR (Variable Bit Rate).

ꢀ When playing back files recorded as

VBR (Variable Bit Rate) files, the play

time will not be correctly displayed if

fast−forward or reverse operations are

used.

ꢀ The MP3/WMA player plays back files

with .mp3 or .wma file extensions as

MP3 or WMA files. To prevent noise

and playback errors, use the appropri-

ate file extensions.

Playable bit rates

MP3 files:

MPEG1 LAYER3—64 to 320 kbps

MPEG2 LSF LAYER3—64 to 160 kbps

WMA files:

ꢀ It is not possible to check folders that

do not include MP3/WMA files.

ꢀ Multi−session compatible CDs can also

be played.

ꢀ MP3/WMA files in folders up to 8 lev-

els deep can be played. However, the

start of playback may be delayed when

using discs containing numerous levels

of folders. For this reason, we recom-

mend creating discs with no more than

two levels of folders.

ꢀ MP3 files are compatible with the ID3

Tag Ver. 1.0, Ver. 1.1, Ver. 2.2, and

Ver. 2.3 formats. The unit cannot dis-

play disc title, track title and artist

name in other formats.

Ver. 7, 8 CBR—48 to 192 kbps

Ver. 9 CBR—48 to 320 kbps

ꢀ It is possible to play up to 192 folders

or 255 files on one disc.

282

CD−R and CD−RW discs

ꢀ Recordings on CD−R/CD−RW cannot

be played using the DDCD (Double

Density CD) system.

ꢀ CD−R/CD−RW discs that have not been

subject to the “finalizing process” (a

proc ess that allows discs to be played

on a conventional CD player) cannot

be played.

scratches or dirt on the disc, or dirt,

condensation, etc. on the lens of the

unit.

This is a method of embedding track−re-

lated information in an MP3 file. This em-

bedded information can include the track

title, the artist’s name, the album title, the

music genre, the year of production, com-

ments and other data. The contents can

be freely edited using software with ID3

tag editing functions. Although the tags

are restricted to the number of characters,

the information can be viewed when the

track is played back.

ꢀ It may not be possible to play discs

recorded on a personal computer de-

pending on the application settings and

the environment. Record with the cor-

rect format. (For details, contact the

appropriate application manufacturers of

the applications.)

ꢀ The play order of the compact disc

with the structure shown above is as

follows:

001.mp3

002.wma . . .

006.mp3

ꢀ CD−R/CD−RW discs may be damaged

by direct exposure to sunlight, high

temperatures or other storage condi-

tions. The unit may be unable to play

some damaged discs.

WMA Tag—

WMA files can contain a WMA tag that is

used in the same way as an ID3 tag.

WMA tags carry information such as track

title, artist name.

ꢀ If you insert a CD−RW disc into the

MP3/WMA player, playback will begin

more slowly than with a conventional

CD or CD−R disc.

283

ISO 9660 format—

WMA—

This is the international standard for the

formatting of CD−ROM folders and files.

For the ISO 9660 format, there are two

levels of regulations.

WMA (Windows Media Audio) is an audio

compression format developed by Micro-

soft. It compresses files into a size small-

er than that of MP3 files. The decoding

formats for WMA files are Ver. 7, 8, and

9.

Level 1:

The file name is in 8.3 format (8 charac-

ter file names, with

a

3

character file

extension. File names must be composed

of one−byte capital letters and numbers.

The “_” symbol may also be included.)

Level 2:

The file name can have up to 31 charac-

ters (including the separation mark “.” and

file extension). Each folder must contain

fewer than 8 hierarchies.

m3u—

Playlists created using “WINAMP” software

have a playlist file extension (.m3u).

MP3—

MP3 is an audio compression standard

determined by a working group (MPEG) of

the ISO (International Standard Organiza-

tion). MP3 compresses audio data to

about 1/10 the size of that on convention-

al discs.
