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
÷ 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.
