"F15"---This indication appears when the Down switch fails to turn ON since the magnetic head
fails to move up/down normally (Due to trouble of the magnetic head or trouble of the magnetic
head up/down motor) or the magnetic head P.C.B. is out of position or a foreign matter has mixed

In such a case, check the peripheral parts of the magnetic head, repair or replace defective parts
with normal ones.
