INSTALLING THE MECHANISM ON MAIN PWB
Lower vertically the mechanism, paying attention to the
mechanism edge mode SW position, (Set the mode SW
position to 270
°
and make sure the master cam position
hole also in 270
°
position) and install the mechanism with
due care so that the parts are not damaged.
* Please make sure to insert correctly.
If not, strange moving will occur and will couse mecha-
nism damage.
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.
2. Mechanical initial setting
• Rotate the worm gear by pushing the flange manually
until return to initial position.
• When apply power supply to rotate the loading motor,
please remove/unsolder at least one terminal wire.
• If voltage applied to loading motor without disconnecting
the terminal wire, there is a possibility the capstan motor
IC will damage.
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.
• The maximum applied voltage is 9V. If more than 9V,
there is a possibility the mechanism will damage.
• After ascertaining the return to the initial set position
install the cassette housing in the specified position. (This
method is applied only for the mechanism.)
