Correct Handling  
PRECAUTIONS  
Never Attempt the Following  
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.  
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.

Inserting Discs  
Your player accepts only one disc at a time for playback. Do not  
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.  
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.  
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.

What is MP3?  
File Name Search mode  
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.  
Press 8 or 9 to select another Folder.  
2
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.  
Select the desired file by turning the Rotary  
encoder within 10 seconds.

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.  
File Name search cannot be made during M.I.X. play.

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)

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

Corresponding File Systems  
Terminology  
This device supports discs formatted with ISO9660 Level 1 or Level 2.  
Bit rate  
Under the ISO9660 standard, there are some restrictions to  
remember.  
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.  
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).  
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.  
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.  
Encoding  
Converting music CDs, WAVE (AIFF) files, and other sound files  
into the specified audio compression format.  
Formats supported  
Tag  
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.  
Song information such as track titles, artist names, album names,  
etc., written into MP3/WMA files.  
MP3: ID3 tag  
WMA: WMA tag  
Order of files  
Root folder  
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.  
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.  
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.  
Warning  
MAKE THE CORRECT CONNECTIONS.  
Failure to make the proper connections may result in fire or  
product damage.  
USE SPECIFIED ACCESSORY PARTS AND INSTALL THEM  
SECURELY.  
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.  
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.  
BEFORE WIRING, DISCONNECT THE CABLE FROM THE  
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.  
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 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.  
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.  
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 short-  
circuit.  
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.  
• 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/CDE-  
9841 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.  
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.  
• 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.
