There are two initial setting methods, namely electrical and
mechanical.

So as to perform initial setting of mechanism execute the
Step 1 of Installation of cassette housing. After ascertaining
the return to the initial setting position (*1) install the

Lower vertically the mechanism, paying attention to the
mechanism edge, and install the mechanism with due care
so that the parts are not damaged. So as to fix the mecha-
nism to the main PWB install two housings. (Fit the antenna
cover to one of them. For other, fix the vicinity of loading
motor and solder joint side of main PWB.) Connect again
the FFC cable (AA-MH, AD-ME, AH-MH) between the
mechanism and the main PWB.

When installing the mechanism chassis on the PWB unit,
take care so as to prevent deformation due to contact of
mechanism chassis with REC TIP SW.
