Careless handling duringrepair can reduce life drastically.When repairing, make sure that you are connected with thesame potential as the mass of the set via a wristband withresistance. Keep components and tools at this potential.f ATTENTIONTous les IC et beaucoup d´autres semi-conducteurs sontsensibles aux décharges statiques (ESD). Leur longévitepourrait être considérablement écourtée par le fait qu´aucuneprécaution nést prise à leur manipulation.Lors de réparations, s´assurer de bien être relié au mêmepotentiel que la masse de l´appareil et enfileer le braceletserti d´une résistance de sécurité.Veiller à ce que les composants ainsi que les outils que l´onutilise soient également à ce potentiel.d WARNUNGAlle ICs und viele andere Halbleiter sind empfindlichgegenüber elektrostatischen Entladungen (ESD).Unsorgfältige Behandlung im Reparaturfall kann dieLebensdauer drastisch reduzieren.Sorgen Sie dafür, daß sie im Reparaturfall über ein Puls-armband mit Widerstand mit dem Massepotential desGerätes verbunden sind.Halten Sie Bauteile und Hilfsmittel ebenfalls auf diesemPotential.WAARSCHUWINGAlle IC´s en vele andere halfgeleiders zijn gevoelig voorelectrostatische ontladingen (ESD).Onzorgvuldig behandelen tijdens reparatie kan de levensduurdrastisch doen vermindern.

Do not use any cleaning agents as they may have a corrosive effect. Do not expose the CD player, batteries or CDs to humidity, rain,sand or excessive heat (caused by heating equipment or direct sunlight). This CD player can play all kinds of Audio Discs such as CD-Recordables, CD-Rewriteables and CD-Text CDs. Do nottry to play a CD-ROM, CD-I, CDV or computer CD. If the CD player cannot read CDs correctly use a commonly available cleaning CD to clean the lens before taking the CD player to repair. Other cleaning methods may destroy the lens.Always keep the tray closed to avoid dust on the lens. The lens may cloud over when the CD player is suddenly moved from cold to warm surroundings. Playing a CD is not possible then. Leave the CD player in a warm environment until the moisture evaporates. Toclean a CD, wipe it in a straight line from the center toward the edge using a soft, lint-free cloth. A cleaning agent may damage the disc! Never write on a CD or attach a sticker to it.
