This unit displays the diagnosis contents of abnormalities and the mechanism mode on its display panel in 2-digit numbers.
When the head playback output has dropped, the “L” sign will be blinked. Some models (listed later) will also display the cylinder
rotation accumulated time.
These display shows the outline of the problems. Use it as a reference when servicing the unit.

When the STOP button on the remote control is pressed for about 10 seconds continuously, the self- diagnosis number will be
displayed on the reception channel display of the display panel and number indicating the failed mechanism mode (changed
mode when being shifted) on the tape counter “seconds” display for 3seconds each.
During self-diagnosis display, displays other than the diagnosis number/mechanism mode number and the cylinder
accumulated rotation time display described later (some models only) will be turned off and when displays end, the normal
display will be returned automatically.

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.

point where it just disappears from the monitor TV.
Confirm by monitor TV that there is no beat and satura-
