<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.
<Note 2b>
• When reattaching the Front panel assembly, pay careful at-
tention to the switch lever not to make it touch the switch
knob “b” of the Main board assembly from the side.
<Note 2c>
• 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 page 1-2).
• When reattaching the Mechanism assembly to the Main
board assembly, take care not to damage the sensors on
the Main board assembly.
• 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.
• 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.
