1-7. Removing/Installing the Cassette Compartment
n
When removing or installing the cassette compartment, it is possible for screws to fall into the mechanical
deck assembly. To prevent this, it is recommended to magnetize the screwdriver bit moderately.
1. Make sure the unit is in the unthreading end state.
n
To enter the unthreading end state, operate as described below.
(1) Turn on the power and press the EJECT button.
(2) Turn off the power.
2. Remove the upper frame. (Refer to Section 1-6-3.)
3. Remove the four screws and remove the cassette compartment from the mechanical deck assembly.
4. Install the cassette compartment in the reverse order of removal.
m
. During installation, take care that the cassette compartment is not caught by the harness of the AT
head. If so, perform the audio adjustment. (Refer to Section 6-6 of Volume 1 in Maintenance
Manual, Part 2.)
. At installation, open the cassette compartment while pushing the eject lever in the direction of the
arrow for stability.
. At installation, make sure that the release lever of the cassette compartment is in proper alignment
with the eject link assembly as shown in the figure. If the release lever is positioned over the eject
link assembly (for example when the unit is put in the manual eject mode), the eject link assembly
must be aligned. The alignment can be performed in two possible methods:
(1) Turn on the power once and the eject link assembly will return to the proper position automatically.
(2) Turn the manual eject knob clockwise two or three turns while pushing down until the refer-
ence hole of the function cam comes into sight.
. The screws securing the cassette compartment should be torqued as specified.
