Yamaha YHT-580 - Manual (Page 17)

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
÷ Normally-recorded tape is played back in
Dolby NR.
÷ Heads are dirty.
÷ Heads are magnetized.
÷ Basic levels are different for different
cassette decks.
÷ Protective tabs on cassette have been
broken off.
÷ The batteries are exhausted.
÷ The remote control transmitter is operated
from an incorrect distance or angle.
÷ The remote control sensor is lighted
strongly.
Cure
÷ Playback in OFF position.
÷ Clean heads and carry out demagnetiza-
tion with head demagnetizer.
÷ This is not a fault.
÷ Replace cassette tape, or cover tab
holes with tape, etc.
÷ Replace batteries.
÷ Operate it from less than 7 meters (about
23 ft.) and 30°.
÷ Place the unit away from the strong light.
