2-2-3. HOW TO CHECK THE MECHANISM MODE
POSITION
You can tell which mode the mechanism is currently in by
looking at the codes and marking-lines on the crescent
slide on the underside of the mechanism chassis. The
edge of the crescent mounting is used as the reference
line, as shown in Fig.2-2-2, and the marking-lines and
symbols indicating the mechanism modes are displayed
on the crescent slide, which slides against the edge of the
crescent mounting. The mechanism mode is read off from
the marking-line on the slide crescent which is aligned
with the reference-line on the crescent mounting.
Example: In Fig.2-2-2, marking-line 6 is aligned with the
reference-line on the crescent mounting , so the mecha-
nism is seen to be in FF/REW mode.
2-2-4. SELF-DIAGNOSIS DISPLAY
Some models are equipped with the SELF-DIAGNOSIS
DISPLAYS function.
Use it as a means of finding out the symptoms and cause
of the error before performing repairs.
For details, refer to the separate service manual for the
respective models.
