2. HeadOutput Drop Warning Display
When the STOP button on the remote control is pressed for 10 seconds continuously
10 seconds after play starts, "L" will
be displayed blinking at the first digit of the minutes position on the tape counter when the head output is lower than
the specified value to indicate an abnormality.
The cause of the abnormality maybe due to drop in the playback output caused by drop in the efficiency of the cassette used
or head clogging.
Refer to "Head Playback Output Voltage Check" as a means to judge the abnormality.
