inside a car for extended periods may damage and make playback impossible.
¡Some CD-R/RWs can not be played back successfully thanks to incompatibility among writing software, a CD
recorder (CD-R/RW drive) and the discs.
¡This player cannot play the CD-R/RW discs if the session is not closed.
¡This player cannot play the CD-R/RW discs which contains other than CD-DA or MP3/WMA data.

fusible peut déclencher de la fumée, un incendie et
endommager l’appareil.
Lors du montage, observer les avertissements
suivants.
❑
Avant de procéder au montage, débrancher le câble à la
borne négative (–) de la batterie.
Procéder à la filerie et au montage quand la borne négative (–) de
batterie est connectée peut provoquer un choc électrique ou une
blessure dû à un court-circuit. Certaines voitures équipées de
système électrique de sécurité sont dotées de procédures
spécifiques pour la déconnexion de la borne de batterie.
LE FAIT DE NE PAS SUIVRE LA PROCEDURE PEUT CONDUIRE A
UNE ACTIVATION INVOLONTAIRE DU SYSTEME ELECTRIQUE DE
SECURITE QUI POURRAIT ENDOMMAGER LE VEHICULE ET
PROVOQUER DES BLESSURES PERSONNELLES, VOIRE LA
MORT.
❑
Ne jamais utiliser de composants en relation à la sécurité
pour le montage, la mise à la masse et autres fonctions
de ce type.
Ne pas utiliser de composants du véhicule en relation à la sécurité
(réservoir à carburant, freins, suspension, direction assistée,
pédales, coussins gonflables, etc.,) lors de la fixation ou de la
fixation de l’appareil et de ses accessoires.
❑
Le montage de l’appareil devant la housse du coussin
gonflable ou dans tout endroit où elle interfère avec le
fonctionnement du coussin gonflable est interdite.
❑
Vérifier la tuyauterie, le réservoir à carburant, le câblage
électrique et les autres articles avant d’installer
l’appareil.
S’il est nécessaire de faire un trou dans le châssis pour monter
l’appareil ou procéder à sa filerie, vérifier d’abord dans quels
endroits le faisceau des fils, le réservoir à carburant, la filerie
électrique sont situés. Puis, faire le trou, à partir de l’extérieur si
possible.
❑
Ne jamais installer l’appareil dans un endroit où il
interfère avec le champ de vision.
❑
Ne jamais bifurquer le cordon d’alimentation pour
alimenter un autre équipement.
❑
Après le montage et la filerie, il est nécessaire de vérifier
le bon fonctionnement des autres appareils électriques.
Le fait de continuer à les utiliser dans des conditions anormales
peut déclencher un incendie, provoquer un choc électrique ou un
accident de la route.
❑
En cas de montage dans un véhicule équipé de coussins
gonflables, vérifier les avertissements et précautions
préconisés par le constructeur automobile avant de
procéder au montage.
❑
S’assurer que les fils n’interfèrent pas avec la conduite ou
le fait d’entrer dans le véhicule et d’en sortir.
❑
Pour éviter un court-circuit, isoler tous les fils visibles.
