Anvnd medfljande skivmagasin eller skivmagasinet XA-250. Skivmagasinet XA-10B kan anvndas med denna enhet. Anvnd inget annat magasin, eftersom det kan orsaka fel. Utilize o carregador de discos fornecido ou o carregador XA-250. No pode utilizar o carregador de discos XA-10B com este aparelho. Se utilizar outro carregador qualquer pode provocar uma avaria.
Use the supplied disc magazine or the disc magazine XA-250. The disc magazine XA-10B can not be used with this unit. If you use any other magazine, it may cause a malfunction. Emplee el cargador de discos suministrado o el XA-250. El cargador de discos XA-10B no puede utilizarse con esta unidad. Si emplea otro tipo de cargador, puede producir fallos de funcionamiento.

If the disc magazine does not lock properly Take out the magazine, and after pressing the EJECT button, reinsert it. Si el cargador de discos no encaja adecuadamente. Extraiga el cargador y, despus de presionar el botn EJECT, vuelva a insertarlo. Nr skivmagasinet inte kommer p plats ordentligt Ta ut skivmagasinet. Tryck drefter p EJECT och stt i det igen. Se o carregador de discos no fechar bem Retire o carregador, carregue na tecla EJECT e volte a introduzi-lo. EJECT
Use the unit with the door closed Otherwise, foreign matter may enter the unit and contaminate the lenses inside the changer. Emplee la unidad con la puerta cerrada. De lo contrario podran entrar objetos extraos y contaminar las lentes del interior del cambiador. Kom ihg att stnga locket till skivmagasinsfacket Fr att frhindra frmmande freml frn att trnga in i CD-vxlare och smutsa ned de inbyggda linserna. Utilize o aparelho com a porta fechada Caso contrrio, objectos estranhos podero penetrar no aparelho e sujar as lentes no interior do permutador.
Notes on the disc magazine
Do not leave the disc magazine in locations with high temperatures and high humidity such as on a car dashboard or in the rear window where the disc magazine will be subjected to direct sunlight. Do not place more than one disc at a time onto one tray, otherwise the changer and the discs may be damaged. Do not drop the disc magazine or subject it to a violent shock.

CDX-616 CDX-2 1

3.5 mm Notes Because the CDX-616/CDX-600 does not have the custom file function, even if it is connected to a master unit with the custom file function, the function will not be available. But if multiple changers are connected, and one of them has the custom file function, this unit will also be able to use the function. For connecting two or more changers, the XA-C30 source selector (optional) is necessary. Notas Como el CDX-616/CDX-600 no posee la funcin de archivo personalizado, aunque se conecte a una unidad principal con dicha funcin, sta no estar disponible. Pero si ha conectado mltiples cambiadores y uno de ellos posee la funcin de archivo personalizado, est unidad tambin podr emplear dicha funcin. Si desea conectar dos o ms cambiadores, es preciso utilizar un selector de fuente XA-C30 (opcional).

Suspended installation

When the unit is to be installed under the rear tray etc. in the trunk compartment, make sure the following provisions are made. Choose the mounting location carefully so the unit can be installed horizontally. Make sure the unit does not hinder the movement of the torsion bar spring etc. of the trunk lid.
