SHOCK, FIRE HAZARD SERVICE TEST :
CAUTION : After servicing this appliance and prior to returning to customer, measure the resistance between either primary AC
cord connector pins ( with unit NOT connected to AC mains and its Power switch ON ), and the face or Front Panel of product and
controls and chassis bottom.
Any resistance measurement less than 1 Megohms should cause unit to be repaired or corrected before AC power is applied,
and verifi ed before it is return to the user/customer.
In case of diffi culties, do not hesitate to contact the Technical
Department at above mentioned address.

ABOUT DISCS
Playable discs
* Finalize is the process to make a CD-R/CD-RW
playable for players (not recorders)
* Some discs may not be able to be played
depending on condition of the discs and
recording software.
Structure of audio CD
Audio CDs contain music tracks only.
You can play them in conventional style through a
stereo system, using the keys on the remote
control and/or front panel.
About playing copy-controlled CDs
Some copy-controlled CDs may not conform to
official CD standards. They are special discs and
may not play on the CR401.
Discs made on personal computers
Discs made on personal computers, including
those of a compatible format, may not work
properly in the CR401 because of incorrect
settings in the disc burning software. Check the
manual supplied with your disc burning software
for additional compatibility information.
Audio CD (CD-DA)
CD-R/CD-RW
Finalized CD-R and CD-RW discs
recorded in the CD-DA format,
MP3 format can be played with
the unit.
2
MP3 compatibility
• MP3 discs must be ISO 9660 Level 1 or Level 2,
Joliet compliant. Supported formats: Mode 1,
Mode 2.
• Folders can be up to eight levels deep.
•
MP3 files must be MPEG-1/MPEG-2 Audio Layer
3 format with a sampling rate of between 16 kHz
and 48 kHz and a bit-rate of between 32 kbps and
320 kbps (128 kbps or 192 kbps recommended).
Incompatible files cannot be played.
• Fixed bit-rate MP3 files are recommended,
however, variable bit-rate (VBR) MP3 files
between 8 kbps and 320 kbps are supported
(Playing times may display incor-rectly).
• MP3 files must have a “.mp3” or “.MP3” file
name extension. MP3 files without the proper
extension will not be recognized. To prevent
noise and malfunction, do not use these
extensions for other types of files.
• The CR401 supports up to 500 MP3 files and up
to 200 folders per disc. (In this case, Disc and
File names contain 30 characters and Folder
names contain 20 characters.) Files and folders
in excess of this cannot be played. Note that if
the file and folder structure is very complicated,
the CR401 may not be able to read or play all of
the MP3 files on the disc. If the disc, folder or file
names contain many characters, the CR401
may not support 500 MP3 files.
• Disc names may contain up to 30 characters.
File and folder names may contain up to 60
characters.
• The maximum time that can be displayed for a
single track is 99 minutes and 59 seconds.
• The remaining time cannot be displayed when
playing MP3 files.
•
Multisession discs are supported, however,
some multisession discs may take a long time to
load and some may not load at all. When burning
CDs we recommend that you use a single
session (disc-at-once), and select “Disc Close.”
• The ID3 tag version 1.0 is supported.
Notes
• With CD-ROM, CD-R, and CD-RW discs that
contain many files and folders, and files other
than MP3s, it may take a long time to read the
disc. We recommend that you include only MP3
files on your discs, use about 20 folders, and
limit folder nesting to three levels deep.
• In this manual, MP3 files are referred to as
tracks.

3. WARNING AND LASER SAFETY INSTRUCTIONS
GB
WARNING
All ICs and many other semi-conductors are
susceptible to electrostatic discharges (ESD).
Careless handling during repair can reduce
life drastically.
When repairing, make sure that you are
connected with the same potential as the
mass of the set via a wrist wrap with
resistance.
Keep components and tools also at this
potential.
F
ATTENTION
D
WARNUNG
I
WAARSCHUWING
AVVERTIMENTO
NL
Alle IC’s en vele andere halfgeleiders zijn
gevoelig voor elektrostatische ontladingen
(ESD).
Onzorgvuldig behandelen tijdens reparatie
kan de levensduur drastisch doen
verminderen.
Zorg ervoor dat u tijdens reparatie via een
polsband met weerstand verbonden bent met
hetzelfde potentiaal als de massa van het
apparaat.
Houd componenten en hulpmiddelen ook op
ditzelfde potentiaal.
Tous les IC et beaucoup d’autres semiconducteurs sont sensibles aux décharges
statiques (ESD).
Leur longévité pourrait être considérablement
écourtée par le fait qu’aucune précaution
n’est prise a leur manipulation.
Lors de réparations, s’assurer de bien être
relié au même potentiel que la masse de
l’appareil et enfiler le bracelet serti d’une
résistance de sécurité.
Veiller a ce que les composants ainsi que les
outils que l’on utilise soient également a ce
potentiel.
GB
Safety regulations require that the set be restored to its original condition
and that parts which are identical with those specified be used.
NL
Veiligheidsbepalingen vereisen, dat het apparaat in zijn oorspronkelijke
toestand wordt terug gebracht en dat onderdelen, identiek aan de
gespecifieerde worden toegepast.
Alle IC und viele andere Halbleiter sind
empfindlich gegen elektrostatische
Entladungen (ESD).
Unsorgfältige Behandlung bei der Reparatur
kann die Lebensdauer drastisch vermindern.
Sorgen sie dafür, das Sie im Reparaturfall
über ein Pulsarmband mit Widerstand mit
dem Massepotential des Gerätes verbunden
sind.
Halten Sie Bauteile und Hilfsmittel ebenfalls
auf diesem Potential.
D
Bei jeder Reparatur sind die geltenden Sicherheitsvorschriften zu beachten.
Der Originalzustand des Gerats darf nicht verandert werden.
Fur Reparaturen sind Original-Ersatzteile zu verwenden.
I
Le norme di sicurezza esigono che l’apparecchio venga rimesso nelle
condizioni originali e che siano utilizzati pezzi di ricambiago idetici a quelli
specificati.
Tutti IC e parecchi semi-conduttori sono
sensibili alle scariche statiche (ESD).
La loro longevita potrebbe essere fortemente
ridatta in caso di non osservazione della piu
grande cauzione alla loro manipolazione.
Durante le riparazioni occorre quindi essere
collegato allo stesso potenziale che quello
della massa dell’apparecchio tramite un
braccialetto a resistenza.
Assicurarsi che i componenti e anche gli
utensili con quali si lavora siano anche a
questo potenziale.
F
“Pour votre sécurité, ces documents
doivent être utilisés par des
spécialistes agrées, seuls habilités à
réparer votre appareil en panne.”
Les normes de sécurité exigent que l’appareil soit remis a l’état d’origine et
que soient utilisées les pièces de rechange identiques à celles spécifiées.
LASER SAFETY
This unit employs a laser. Only a qualified service person should remove the cover or attempt to service this
device, due to possible eye injury.
USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURE OTHER THAN THOSE
SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.
AVOID DIRECT EXPOSURE TO BEAM
WARNING
The use of optical instruments with this product will increase eye hazard.
Repair handling should take place as much as possible with a disc loaded inside the player
