Yamaha KX-580 Owner's Manual - Page 17

Fault Playback sound is muffled and high frequencies are inaudible. When playing back tapes recorded on other decks, meter deflections are greater (smaller) than when recorded. Recordings cannot be made with TIMER REC (deck only plays back) (except KX-380). The remote control transmitter cannot be operated. Cause Cure ÷ Normally-recorded tape is played back in Dolby NR. ÷ Heads are dirty. ÷ Heads are magnetized. ÷ Playback in OFF position. ÷ Clean heads and carry out demagnetization with head demagnetizer. ÷ Basic levels are different for different cassette decks. ÷ This is not a fault. ÷ Protective tabs on cassette have been broken off. ÷ Replace cassette tape, or cover tab holes with tape, etc. ÷ The batteries are exhausted. ÷ The remote control transmitter is operated from an incorrect distance or angle. ÷ The remote control sensor is lighted strongly. ÷ Replace batteries. ÷ Operate it from less than 7 meters (about 23 ft.) and 30°. ÷ Place the unit away from the strong light.
