2011 MAZDA MODEL 2 Owners Manual

Black plate (177,1)
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.
AM wave
FM wave
FM wave
100—200 km (60—120 miles) Ionosphere
Atmospheric conditions can also affect
FM reception. High humidity will cause
poor reception. However, cloudy days
may provide 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.
Reflected wave
Direct
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
frequencies, the original station may be
temporarily lost and the second station
picked up. At this time there will be some
noise from this disturbance.
Station 2
88.3 MHz

Operating Tips for CD Player
Condensation phenomenon
Immediately after turning on the heater
when the vehicle is cold, the CD or
optical components (prism and lens) in the
CD 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 the CD player
The following precautions should be
observed.
lDo not spill any liquid on the audio
system.
lDo not insert any objects, other than
CDs, into the slot.

lThe CD revolves at high speed within
the unit. Defective (cracked or badly
bent) CDs should never be used.
lDo not use non-conventional discs
such as heart-shaped, octagonal discs,
etc. The disc may not eject resulting in
a malfunction.
lIf the memory portion of the CD is
transparent or translucent, do not use
the disc.

lA 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 the CD
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.
lWhen driving over uneven surfaces,
the sound may jump.
lThe CD player has been designed to
play CDs bearing the identification
logo as shown below. No other discs
can be played.

lUse discs that have been legitimately
produced. If illegally-copied discs such
as pirated discs are used, the system
may not operate properly.
lBe 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.
lDo 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.
lDust, 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.
lDo 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.
lInsert discs one by one. If two discs are
inserted at the same time, the system
may not operate properly.
lThe CD player ejects the CD if the CD
is inserted upside down. Also dirty
and/or defective CDs may be ejected.
lDo not insert cleaning discs in the CD
player.
lDo not insert any disc with a peel-off
seal affixed to it.
lThis 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.
lStoring CDs in the vehicle exposed to
direct sunlight or high temperature may
damage the CD-R/CD-RWs, and make
them unplayable.
lCD-R/CD-RW exceeding 700 MB
cannot be played.
lThis 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.)
lIt 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.
lThe period from when a CD-RW is
inserted to when it begins playing is
longer than a normal CD or CD-R.
lCompletely read the instruction manual
and cautions for CD-R/CD-RWs.
lDo 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.

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.
Multi-session
A session is the complete amount of data
recorded from the beginning to the end of
a single period of CD-ROM, CD-R/CD-
RW data recording. Multi-session refers to
the existence of data from two or more
sessions on a single disc.
Sampling
Refers to the process of encoding analog
audio data at regular intervals and
converting it to digital data. The sampling
rate refers to the number of times a
sample is taken in one second and is
expressed in Hz units. Increasing the
sampling rate improves the sound quality
but also increases the data size. 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.
ID3 Tag
ID3 tag is a method for storing
information related to the music in an
MP3 file. Information such as track, artist
and album name can be stored. This
content can be freely edited using ID3
editing function software.
VBR
Abbreviation for Variable Bit Rate. While
CBR (Constant Bit Rate) is generally
used, VBR varies the bit rate for audio
compression according to compression
conditions and this allows for
compression with preference given to
sound quality.
q
Operating Tips for WMA
WMA is short for Windows Media Audio
and is the audio compression format used
by Microsoft.
Audio data can be created and stored at a
higher compression ratio than MP3.
