CASSETTE TAPES CASSETTE TAPES There are many different types of cassette tapes available. However, they all conform to standard specifications so any brand may be used with the deck. ÷ Classification of Cassette Tapes by Formulation: Cassette tapes are available in four basic types depending on their formulation, or type of magnetic material and manufacturing process.
DECK B Heads Capstan Capstan Pinch roller DEMAGNETIZATION After 20-30 hours of use, enough residual magnetism will build up on the heads to cause poor high frequency reproduction. At this time you should use a commercially available cassette tape-type head demagnetizer. ÷ When cleaning the tape path or demagnetizing the heads, be sure to follow carefully the instructions of the concerning materials such as cleaning fluid or head demagnetizer.
TROUBLESHOOTING If your cassette deck fails to operate normally, check the following table. It lists common operating errors and simple measures which you can take to correct the problem. If it cannot be corrected, or the symptom is not listed, disconnect the deck’s power cord and contact your authorized YAMAHA dealer or authorized service center for help. Cause Fault Cure Tape doesn’t move in recording or playback. ÷ Power plug is not properly plugged in. ÷ Cassette shell is warped or damaged.
÷ Normally-recorded tape is played back in Dolby NR. ÷ Heads are dirty. ÷ Heads are magnetized. ÷ Play back in OFF position. When playing back tapes recorded on other decks, meter deflections are greater (smaller) than when recorded. ÷ Basic levels are different for different cassette decks. ÷ This is not a fault. The remote control transmitter cannot be operated. ÷ The batteries are exhausted. ÷ The remote control transmitter is operated from an incorrect distance or angle.
Cause Problème Remède ÷ Une bande enregistrée normalement est lue avec Dolby NR. ÷ Les têtes sont sales. ÷ Les têtes sont magnétisées. ÷ Lire en position OFF. Lors de la lecture de bandes enregistrées sur d’autres platines, les déflexions du compteur sont plus grandes (plus petites) qu’à l’enregistrement. ÷ Les niveaux de base sont différents pour diverses platines. ÷ Ceci n’est pas un défaut. La télécommande ne fonctionne pas. ÷ La pile est déchargée.
