(3) HANDLING
METHOD
,
1) The
mode
changes
in
sequence
of
EJECT,
INITIAL, BRAKE,
STOP/REW/FF,
STILL, PLAY,
IDLER, REV when the right side (>) of the mode
selector
button
is kept
on
pressing.
2)
To change
the mode
from
REV to EJECT, press
the left side (>) of the mode
selector button
to select
the desired
mode.
3)
.In the mid position of each mode during a shift
to other
mode, the
"BLANK"
LED
lights. But
the
"PLAY",
"IDLER",
"REV"
LEDs light between
the EJECT
mode
and the INITIAL mode. Be sure
therefore
to check the mechanism
body to see
just
what
state
the
mechanism
is in.
Incidentally,
if
the
mode
selector
is
not
connected
to the mechanism,
the
"BLANK"
LED
lights to indicate
the power
ON.
4)
The
SLOW
position
of POWER
switch
makes
relatively slow motions
in comparison
with the
NORMAL
position.
Note 1: The mode selector drives the loading motor
only, not
affecting
the
head
drum
motor
and
the
capstan
motor.
When
using
the
mode
selector with a cassette
loaded, turn

Note 2: If the
Left side (©) of the mode
selector
(VHJ-0050) key is kept pressed with the
COMPL
cassette
mechanism
removed,
it
might get past the EJECT position, causing
the front helical gear and the front worm

In this condition, since the front
helical gear will
not turn even
if the right side (=) of the mode
selector key is pressed, rotate (push) the front helical
gear clockwise by hand and engage it with the front
worm gear. As there is a misalignment between the

by the mode selector indicator lamps) and the front

Note 3: The
mode
indicator
lamps
show
the
mechanism
operation
mode, but the EJECT
lamp
may
sometimes
fail to
indicate
the
actual
mechanism
operation
mode.
When
setting
the
mechanism
to
the
EJECT
or
INITIAL
mode
for dismounting
or reassembling, fine
adjustment
of the each gear and cam, etc., marking
positions is required after the mode
indicator lamp
has lighted up. Perform
this with the mode selector
switch
in the SLOW
position.
