•
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.
<NOTE4a>
•
Be careful not to damage the connector and wire etc. during connec-
tion and disconnection.
When connecting the wire to the connector, be careful with the wire
direction.
<NOTE4b>
•
When reattaching the Front panel assembly, make sure that the door
opener a of the Cassette holder assembly is lowered in position prior
to the reinstallation.
<NOTE6a>
•
When it is required to remove the screws (S6a) retaining the Mecha-
nism assembly, please refer to the "Procedures for Lowering the Cas-
sette holder assembly"(See on page 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 Mecha-
nism assembly.
•
When reattaching the Mechanism assembly to the Main board as-
sembly, take care not to damage the sensors on the Main board as-
sembly (D3001: LED, Q3002: Start sensor, Q3003: End sensor, S3002
: S cassette switch).
<NOTE6b>
•
The wire (WR6) 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 accommodated between the A/C head
base and the main deck.
<NOTE7>
•
The REC safety board assembly is attached to the SW/Display board
assembly. It is therefore necessary to remove the REC safety board
assembly before removing the SW/Display board assembly.
