2. Mechanical initial setting
• When performing the initial setting manually, press and
turn the flange of the worm as shown in the figure below.
• When applying constant voltage to the loading motor
• Unsolder at least one of the loading motor wires.
If voltage is applied with the wires connected, the IC of
the capstan motor may be damaged.
• The voltage applied to the motor must be maximum of
9V.
If the mechanism is activated by applying excessive
voltage to the motor and is locked in the starting or end
position, it may be damaged.
INSTALLING THE MECHANISM ON MAIN PWB
Lower the mechanism vertically with attention to its edges,
and mount it without damaging the parts. Engage the pin of
the mode SW and the long hole of the master cam.
* Please make sure to insert correctly.
If not, strange moving will occur and will couse mecha-
nism damage.
• After confirming that the mechanism is returned to the
initial setting position, mount the cassette housing to the
specified position. (This method is applied to the
mechanism only.)
• After pushing the tip of the drive lever in the position shown
in the figure, push the cassette housing backward to
mount it to the specified position.
Rotate the flange of worm gear by using thin stick.
CW ---- Loading direction
CCW -- Ejection direction
Note
Be careful not to damage the gear of worm gear
and worm wheel gear. It might cause a strange sound.
PARTS WHICH NEED PARTICULAR CARE
When installing the mechanism chassis on the Main PWB
unit, take care so as to prevent deformation due to contact
of mechanism chassis with REC Tip SW.
