Be sure the temperature inside the vehicle is between +60°C
(+140°F) and –10°C (+14°F) before turning your unit on.

Moisture Condensation

You may notice the CD playback sound wavering due to
condensation. If this happens, remove the disc from the player
and wait about an hour for the moisture to evaporate.

Damaged Disc

Do not attempt to play cracked, warped, or damaged discs.
Playing a bad disc could severely damage the playback
mechanism.

PRECAUTIONS

Never Attempt the Following

Do not grip or pull out the disc while it is being pulled back into
the player by the automatic reloading mechanism.
Do not attempt to insert a disc into the unit when the unit power
is off.

Correct Handling

Do not drop the disc while handling. Hold the disc so you will
not leave fingerprints on the surface. Do not affix tape, paper, or
gummed labels to the disc. Do not write on the disc.

CORRECT

Inserting Discs

Your player accepts only one disc at a time for playback. Do not
attempt to load more than one disc.
Make sure the label side is facing up when you insert the disc.
Your player will automatically eject any disc that is inserted
incorrectly. If the player continues to eject a correctly inserted
disc, push the RESET switch with a pointed object such as a
ballpoint pen.
Playing a disc while driving on a very bumpy road may result in
skips, but this will not scratch the disc or damage the player.

New Discs

As a protective measure to prevent the CD from jamming, the CD
player will automatically eject discs with irregular surfaces or
inserted incorrectly. When a new disc is inserted into the player
and ejected after initial loading, using your finger, feel around the
inside of the center hole and outside edge of the disc. If you feel
any small bumps or irregularities, this could inhibit proper
loading of the disc. To remove the bumps, rub the inside edge of
the hole and outside edge of the disc with a ballpoint pen or other
such instrument, then insert the disc again.

Center Hole

INCORRECT

CORRECT

Disc Cleaning

Fingerprints, dust, or soil on the surface of the disc could cause
the CD player to skip. For routine cleaning, wipe the playing
surface with a clean, soft cloth from the center of the disc to the
outer edge. If the surface is heavily soiled, dampen a clean, soft
cloth in a solution of mild neutral detergent before cleaning the
disc.

Disc Accessories

There are various accessories available on the market for
protecting the disc surface and improving sound quality.
However, most of them will influence the thickness and/or
diameter of the disc. Using such accessories can cause the disc to
be out of standard specifications and may create operational
problems. We recommend not using these accessories on discs
played in Alpine CD players.

About MP3/WMA (CDE-9845/CDE-9843 only)

CAUTION

Except for private use, duplicating audio data (including MP3/
WMA data) or distributing, transferring, or copying it, whether for
free or for a fee, without permission of the copyright holder is
strictly prohibited by the Copyright Act and by international treaty.

What is MP3?

MP3, whose official name is “MPEG-1 Audio Layer 3,” is a
compression standard prescribed by the ISO, the International
Standardization Organization and MPEG which is a joint
activity institution of the IEC.

MP3 files contain compressed audio data. MP3 encoding is
capable of compressing audio data at extremely high ratios,
reducing the size of music files to as much as one-tenth their
original size. This is achieved while still maintaining near CD
quality. The MP3 format realizes such high compression ratios
by eliminating the sounds that are either inaudible to the
human ear or masked by other sounds.

What is WMA?

WMA, or “Windows Media™ Audio,” is compressed audio
data.
WMA allows you to create music files and store them at higher
ratios of compression than MP3 audio data (approx. half
original size). This is achieved while still maintaining CD
quality sound.

Method for creating MP3/WMA files

Audio data is compressed by using MP3/WMA specified
software. For details on creating MP3/WMA files, refer to the
user's manual for that software.
MP3/WMA files that can be played back by this device have
the file extension “mp3” / “wma”. Files with no extension
cannot be played back. (WMA ver. 7.1, 8 and 9 are
supported)

Supported playback sampling rates and bit rates

ID3 tags/WMA tags

This device supports ID3 tag v1 and v2, and WMA tag.
If tag data is in an MP3/WMA file, this device can display the title
(track title), artist name, and album name ID3 tag/WMA tag data.

This device can only display single-byte alphanumeric
characters (up to 30 for ID3 tags and up to 15 for WMA tags)
and the underscore. For non-supported characters, “NO
SUPPORT” (CDE-9845 only) or “NO SUPRT” (CDE-9843/CDE­9841 only) is displayed.
The tag information may not be correctly displayed,
depending on the contents.

Producing MP3/WMA discs

MP3/WMA files are prepared, then written to a CD-R or CD­RW using CD-R writing software. A disc can hold up to 510
files/folders (including Root Folders). However, the maximum
number of folders is 255.

Media supported

The media that this device can play back are CD-ROMs, CD­Rs, and CD-RWs.

Corresponding File Systems

This device supports discs formatted with ISO9660 Level 1 or Level 2.

Under the ISO9660 standard, there are some restrictions to
remember.
The maximum nested folder depth is 8 (including the root
directory). The number of file/folder name characters is
limited.
Valid characters for folder/file names are letters A-Z (all
caps), numbers 0-9, and ‘_’ (underscore).

This device also can play back discs in Joliet, Romeo, etc.,
and other standards that conform to ISO9660. However,
sometimes the file names, folder names, etc., are not
displayed correctly.

Formats supported

This device supports CD-ROM XA, Mixed Mode CD,
Enhanced CD (CD-Extra) and Multi-Session.
This device cannot correctly play back discs recorded with
Track At Once or packet writing.

Order of files

The unit plays the files in the order that the writing software
writes them. Therefore, the playing order may not be the same
as the order you input. The playback order of the folders and
files is shown in the illustration. The folder and file playback
order may differ from the folder no. and file no. indicated in the
display.

Terminology

Bit rate

This is the “sound” compression rate specified for encoding. The higher
the bit rate, the higher the sound quality, but also the larger the files.

Sampling rate

This value shows how many times per second the data is sampled
(recorded). For example, music CDs use a sampling rate of 44.1
kHz, so the sound is sampled (recorded) 44,100 times per second.
The higher the sampling rate, the higher the sound quality, but also
the larger the volume of data.

Encoding

Converting music CDs, WAVE (AIFF) files, and other sound files
into the specified audio compression format.

Tag

Song information such as track titles, artist names, album names,
etc., written into MP3/WMA files.
MP3: ID3 tag
WMA: WMA tag

Root folder

The root folder is found at the top of the file system. The root folder
contains all folders and files.

Installation and Connections

Before installing or connecting the unit, please read the
following and pages 2 and 3 of this manual thoroughly
for proper use.

Warning

MAKE THE CORRECT CONNECTIONS.

Failure to make the proper connections may result in fire or
product damage.

USE ONLY IN CARS WITH A 12 VOLT NEGATIVE GROUND.

(Check with your dealer if you are not sure.) Failure to do so may
result in fire, etc.

BEFORE WIRING, DISCONNECT THE CABLE FROM THE
NEGATIVE BATTERY TERMINAL.

Failure to do so may result in electric shock or injury due to
electrical shorts.

DO NOT ALLOW CABLES TO BECOME ENTANGLED IN
SURROUNDING OBJECTS.

Arrange wiring and cables in compliance with the manual to
prevent obstructions when driving. Cables or wiring that obstruct
or hang up on places such as the steering wheel, gear lever, brake
pedals, etc. can be extremely hazardous.

DO NOT SPLICE INTO ELECTRICAL CABLES.

Never cut away cable insulation to supply power to other
equipment. Doing so will exceed the current carrying capacity of
the wire and result in fire or electric shock.

DO NOT DAMAGE PIPE OR WIRING WHEN DRILLING
HOLES.

When drilling holes in the chassis for installation, take
precautions so as not to contact, damage or obstruct pipes, fuel
lines, tanks or electrical wiring. Failure to take such precautions
may result in fire.

DO NOT USE BOLTS OR NUTS IN THE BRAKE OR
STEERING SYSTEMS TO MAKE GROUND CONNECTIONS.

Bolts or nuts used for the brake or steering systems (or any other
safety-related system), or tanks should NEVER be used for
installations or ground connections. Using such parts could
disable control of the vehicle and cause fire etc.

DO NOT INSTALL IN LOCATIONS WHICH MIGHT HINDER
VEHICLE OPERATION, SUCH AS THE STEERING WHEEL
OR GEARSHIFT.

Doing so may obstruct forward vision or hamper movement etc.
and results in serious accident.

Caution

HAVE THE WIRING AND INSTALLATION DONE BY
EXPERTS.

The wiring and installation of this unit requires special technical
skill and experience. To ensure safety, always contact the dealer
where you purchased this product to have the work done.

USE SPECIFIED ACCESSORY PARTS AND INSTALL THEM
SECURELY.

Be sure to use only the specified accessory parts. Use of other
than designated parts may damage this unit internally or may not
securely install the unit in place. This may cause parts to become
loose resulting in hazards or product failure.

ARRANGE THE WIRING SO IT IS NOT CRIMPED OR
PINCHED BY A SHARP METAL EDGE.

Route the cables and wiring away from moving parts (like the
seat rails) or sharp or pointed edges. This will prevent crimping
and damage to the wiring. If wiring passes through a hole in
metal, use a rubber grommet to prevent the wire’s insulation from
being cut by the metal edge of the hole.

DO NOT INSTALL IN LOCATIONS WITH HIGH MOISTURE
OR DUST.

Avoid installing the unit in locations with high incidence of
moisture or dust. Moisture or dust that penetrates into this unit
may result in product failure.

Precautions

• Be sure to disconnect the cable from the (–) battery post before
installing your CDE-9845/CDE-9843/CDE-9841. This will
reduce any chance of damage to the unit in case of a short­circuit.

• Be sure to connect the color coded leads according to the
diagram. Incorrect connections may cause the unit to
malfunction or damage to the vehicle’s electrical system.

• When making connections to the vehicle’s electrical system, be
aware of the factory installed components (e.g. on-board
computer). Do not tap into these leads to provide power for
this unit. When connecting the CDE-9845/CDE-9843/CDE­9841 to the fuse box, make sure the fuse for the intended
circuit of the CDE-9845/CDE-9843/CDE-9841 has the
appropriate amperage. Failure to do so may result in damage to
the unit and/or the vehicle. When in doubt, consult your
ALPINE dealer.

• The CDE-9845/CDE-9843/CDE-9841 uses female RCA-type
jacks for connection to other units (e.g. amplifier) having RCA
connectors. You may need an adaptor to connect other units. If
so, please contact your authorized ALPINE dealer for
assistance.

• Be sure to connect the speaker (–) leads to the speaker (–)
terminal. Never connect left and right channel speaker cables
to each other or to the vehicle body.
