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.

nOperating Tips for In-Dash CD
Changer
Condensation phenomenon
Immediately after turning on the heater
when the vehicle is cold, the CD or optical
components (prism and lens) in the In-dash
CD changer 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 In-dash CD changer
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 the In-dash CD changer
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.

nOperating tips for MP3
l
This audio system handles MP3 files that
have been recorded on CD-R/CDRW/CD-
ROMs. Discs that have been recorded
using the following formats can be played:
• ISO9660 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.
NOTE
Supply of this product only conveys a
license for private, non-commercial use
and does not convey a license nor imply
any right to use this product in any
commercial (i.e. revenue-generating) real
time broadcasting (terrestrial, satellite,
cable and/or any other media),
broadcasting/streaming via the Internet,
intranets and/or other networks or in other
electronic content distribution systems,
such as pay-audio or audio-ondemand
applications. An independent license for
such use is required. For details, please
visit http://www.mp3licensing.com.
CAUTION
This unit can only play MP3 files that have
an MP3 file extension (.mp3) attached.
Do not attach an MP3 file extension to
any other type file as it could cause noise
to be emitted or a malfunction in the unit.

The liquid crystal display may not open if the power supply had been interrupted due to the
vehicle battery being disconnected.
l If the liquid crystal display stays open/closed (or partly opened) and does not move when
the liquid crystal display is pressed, turn the ignition switch and then on again. Then try the
open/close operation again. If the liquid crystal display still does not move, contact an
Authorized Mazda Dealer.
The beep sound and voice guidance related to the audio operation are not heard while a
Bluetooth Hands-Free is being used.
Operating Tips for Display
nDo not place any objects on the dashboard. If you drop any objects onto
the dashboard or spill liquid on it, it may result in system malfunction.
nBe careful not to pinch your hands or fingers when the liquid crystal
display is closed.
nDo not open/close the liquid crystal display manually. It may damage the
equipment.
