nRadio Reception
AM characteristics
AM signals bend around such things as
buildings or mountains and bounce off the
ionosphere. Therefore, they can reach
longer distances than FM signals. Because
of this, two stations may sometimes be
picked up on the same frequency at the
same time.
FM characteristics
An FM broadcast range is usually about 40–
50 km (25–30 miles) from the source.
Because of extra coding needed to break the
sound into two channels, stereo FM has
even less range than monaural (non-stereo)
FM. Signals from an FM transmitter are similar to
beams of light because they do not bend
around corners, but they do reflect.
Unlike AM signals, FM signals cannot travel
beyond the horizon. Therefore, FM stations
cannot be received at the great distances
possible with AM reception.
Atmospheric conditions can also affect FM
reception. High humidity will cause poor
reception. However, cloudy days may pro-
vide better reception than clear days.
Multipath noise
Since FM signals can be reflected by
obstructions, it is possible to receive both the
direct signal and the reflected signal at the
same time. This causes a slight delay in
reception and may be heard as a broken
sound or a distortion. This problem may also
be encountered when in close proximity to
the transmitter.

Audio Operation
Flutter/Skip noise
Signals from an FM transmitter move in
straight lines and become weak in valleys
between tall buildings, mountains, and other
obstacles. When a vehicle passes through
such an area, the reception conditions may
change suddenly, resulting in annoying
noise.
Weak signal noise
In suburban areas, broadcast signals
become weak because of distance from the
transmitter. Reception in such fringe areas is
characterized by sound breakup.Strong signal noise
This occurs very close to a transmitter tower.
The broadcast signals are extremely strong,
so the result is noise and sound breakup at
the radio receiver.
Station drift noise
When a vehicle reaches the area of two
strong stations broadcasting at similar fre-
quencies, the original station may be tempo-
rarily lost and the second station picked up.
At this time there will be some noise from
this disturbance.

nOperating Tips for Single CD-MP3
Player
Condensation phenomenon
Immediately after turning on the heater
when the vehicle is cold, the CD or optical
components (prism and lens) in Single CD-
MP3 Player may become clouded with
condensation. At this time, the CD will eject
immediately when placed in the unit. A
clouded CD can be corrected simply by
wiping it with a soft cloth. Clouded optical
components will clear naturally in about an
hour. Wait for normal operation to return
before attempting to use the unit.
Handling Single CD-MP3 Player
The following precautions should be
observed.
l
Do not spill any liquid on the audio system.
l Do not insert any objects, other than CDs,
into the slot.
l The CD revolves at high speed within the
unit. Defective (cracked or badly bent) CDs
should never be used. l
Do not use non-conventional discs such as
heart-shaped, octagonal discs, etc. The
disc may not eject resulting in a
malfunction.
l If the memory portion of the CD is
transparent or translucent, do not use the
disc.
l A new CD may have rough edges on its
inner and outer perimeters. If a disc with
rough edges is used, proper setting will not
be possible and Single CD-MP3 Player will
not play the CD. In addition, the disc may
not eject resulting in a malfunction.
Remove the rough edges in advance by
using a ball-point pen or pencil as shown
below. To remove the rough edges, rub the
side of the pen or pencil against the inner
and outer perimeter of the CD.
l When driving over uneven surfaces,
the sound may jump.

Audio Operation
lUse discs that have been legitimately
produced. If illegally-copied discs such as
pirated discs are used, the system may not
operate properly.
l Be sure never to touch the signal surface
when handling the CDs. Pick up a CD by
grasping the outer edge or the edge of the
hole and the outer edge.
l Do not stick paper or tape on the CD.
Avoid scratching the reverse side (the side
without a label). The disc may not eject
resulting in a malfunction.
l Dust, finger smudges, and dirt can
decrease the amount of light reflected from
the signal surface, thus affecting sound
quality. If the CD should become soiled,
gently wipe it with a soft cloth from the
center of the CD to the edge.
l Do not use record sprays, antistatic
agents, or household spray cleaners.
Volatile chemicals such as benzine and
thinner can also damage the surface of the
CD and must not be used. Anything that
can damage, warp, or fog plastic should
never be used to clean CDs.
l Insert discs one by one. If two discs are
inserted at the same time, the system may
not operate properly.
l Single CD-MP3 Player ejects the CD if the
CD is inserted upside down. Also dirty
and/or defective CDs may be ejected.
l Do not insert any disc with a peel-off seal
affixed to it. Handling Single CD-MP3 Player
l
This unit may not be able to play certain
CD-R/CD-RWs made using a computer or
music CD recorder due to disc
characteristics, scratches, smudges, dirt,
etc., or due to dust or condensation on the
lens inside the unit.
l Storing CDs in the vehicle exposed to
direct sunlight or high temperature may
damage the CD-R/CD-RWs, and make
them unplayable.
l CD-R/CD-RW exceeding 700 MB cannot
be played.
l This unit may not be able to play certain
discs made using a computer due to the
application (writing software) setting used.
(For details, consult the store where the
application was purchased.)
l It is possible that certain text data, such as
titles, recorded on a CD-R/CD-RW may
not be displayed when musical data (CD-
DA) is playing.
l The period from when a CD-RW is
inserted to when it begins playing is longer
than a normal CD or CD-R.
l Completely read the instruction manual
and cautions for CD-R/CD-RWs.
l Do not use discs with cellophane tape
adhering, partially peeled off labels, or
adhesive material exuding from the edges
of the CD label. Also, do not use discs with
a commercially-available CD-R label
affixed. The disc may not eject resulting in
a malfunction.

nOperating tips for MP3
l
This audio system handles MP3 files that
have been recorded on CD-R/CD-RW/CD-
ROMs. Discs that have been recorded
using the following formats can be played:
• ISO 9660 level 1
• ISO 9660 level 2
• Joliet extended format
• Romeo extended format
l This unit handles MP3 files conforming to
the MP3 format containing both header
frames and data frames.
l If a disc has both music data (CD-DA) and
MP3 files, playback of the two file types
differs depending on how the disc was
recorded.
l Packet written discs cannot be played on
this unit.
l This unit does not play CDs recorded
using MP3i (MP3 interactive), MP3 PRO
and RIFF MP3 formats. Specialized glossary
MP3
Abbreviation for “MPEG Audio Layer 3”.
A technical standard for audio compression
as decided by an ISO (International
Organization for Standardization) MPEG
working group.
Use of MP3 allows for audio data to be
compressed to approximately a tenth of the
source data size.
ISO 9660
An international standard for logical
formatting of CD-ROM files and folders.
It is divided into three separate levels based
on differences in file naming procedures,
data configuration and other characteristics.
Bit rate
Refers to the volume of data per second,
expressed in bps (bits per second).
Generally, the larger the number of the
transfer bit rate when compressing an MP3
file, the more information regarding musical
reproduction it carries, and therefore the
better the sound quality.
Packet writing
A general term for the method, similar to that
used for floppy discs or hard drives, of
recording the required file in a single
increment on a CD-R and similar.

Audio Operation
nCD-TEXT
Music CDs are available in which separate
music data including album/title names,
music name, artist name, and other textual
information can be recorded. The data stan-
dard for recording textual information to
these kinds of music CDs is termed CD-
TEXT.
There are two regions of a CD where textual
information can be recorded which include
regions related to the entire CD (Attributes
recorded for the entire CD) and individual
track regions (Attributes recorded for individ-
ual tracks).As for this audio unit, textual information
(Album/artist information), which can be
recorded on individual track regions,
appears on the display. Textual information
(Artist and other information), which can be
recorded to regions related to the entire CD,
does not appear on the display.
Unless all the textual information is input in
one-byte characters, a dotted line (----) will
appear in place of the textual information,
even if one of the characters is not a one-
byte character (Two-byte character).
