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 recording.
Cause
¶ A tape recorded without Dolby NR is
played back with Dolby NR on.
¶ Heads are dirty.
¶ Heads are magnetized.
¶ Basic levels are different for different
cassette decks.
Cure
¶ Playback in OFF position.
¶ Clean heads and carry out
demagnetization with head
demagnetizer.
¶ This is not a fault.
