DISASSEMBLY
1.3 Disassembly/assembly method
1.1 Disassembly flow chart
This flowchart lists the disassembling steps for the cabinet
parts and P. C. boards in order to gain access to item(s) to
be serviced. When reassembling, perform the step(s) in re-
verse order. Bend, route and dress the flat cables as they
were originally laid.
1.2 How to read the disassembly and assembly
Note:
• The bracketed ( ) WR of the connector symbol are as-
signed nos. in priority order and do not correspond to
those on the spare parts list.

<Example>
(1) Order of steps in Procedure
When reassembling, perform the step(s) in the reverse order.
These numbers are also used as the identification (location) No.
of parts Figures.
(2) Part name to be removed or installed.
(3) Fig. No. showing procedure or part location.
(4) Identification of part to be removed, unhooked, unlocked,
released, unplugged, unclamped or unsoldered.
P= Spring, W= Washer, S= Screw, L= Locking tab, SD= Solder,
CN**(WR**)= Remove the wire (WR**) from the connector
(CN**).
<Note 2a>
• When reattaching the Front panel assembly, make sure that
the door opener "a" of the Cassette holder assembly is low-
ered in position prior to the reinstallation.
• When reattaching the Front panel assembly, pay careful at-
tention to the jack "b" at the Jack board assembly to make it
fit the hole of the Front panel assembly.
<Note 2b>
• Be careful not to damage the connector and wire etc. during
connection and disconnection. When connecting the wire
to the connector, be careful with the wire direction.
<Note 4a>
• When it is required to remove the screws (S4a to S4b) re-
taining the Mechanism assembly, please refer to the "Pro-
cedures for Lowering the Cassette holder assembly". (See
on pages 1-2.)
• When removing the Mechanism assembly only, unhook the
two spacers connecting it with the Main board assembly
with pliers from the back side of the Main board assembly
first, and then remove the Mechanism assembly.
• When reattaching the Mechanism assembly to the Main
board assembly, take care not to damage the sensors and
switch on the Main board assembly.
• The wire (WR4a) has excess length that may be loose, as it
is quite long. After inserting the wire and connectors, the
loose portion of the wire should be taken up and accommo-
dated between the A/C head base and the main deck.
<Note 5a>
• The REC safety board assembly is attached to the SW/Dis-
play board assembly. It is therefore necessary to remove
the REC safety board assembly before removing the SW/
Display board assembly.
<Note 5b>
• When reattaching the Jack board assembly, should be at-
tach the Jack board assembly to the Bottom chassis before
attaching the SW/Display board assembly.
<Note 7a>
• When attaching the Bottom cover, make sure that the Earth
plate of the Bottom cover is passed through the hole of the
Bottom chassis and then touches the GND (Ground) on the
Main board assembly.
