The tape does not record.
• The tab has been removed from the cassette (see
“To save a tape permanently” on page 25).
• The tape has reeled to the end.
The tape does not record nor play or there is a
decrease in sound level.
• The heads are dirty. (See “Cleaning the tape
heads” on page 25).
• The record/playback heads are magnetized. (See
“Demagnetizing the tape heads” on page 25).
The tape does not erase completely.
• The record/playback heads are magnetized. (See
“Demagnetizing the tape heads” on page 25).
There is excessive wow or flutter, or the sound
drops out.
• The capstans or pinch rollers are dirty. (See
“Cleaning the tape heads” on page 25).
Noise increases or the high frequencies are erased.
• The record/playback heads are magnetized. (See
“Demagnetizing the tape heads” on page 25).
Tuner
Severe hum or noise (“TUNED” or “STEREO”
flashes in the display).
• Adjust the antenna.
• The signal strength is too weak. Connect the
external antenna.
A stereo FM program cannot be received in stereo.
• Press FM MODE so that “MONO” disappears.
