Yamaha KX-493 Owner's Manual - Page 17

ENGLISH 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. (KX-493 only) Recordings cannot be made with TIMER REC (deck only plays back). 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.
