2. INSTALLATION
1. Install the antenna motor shaft into the hole of the oven cavity bot-
tom plate, and turn the flat faces of antenna motor shaft to the left
and right side walls of oven cavity (to fit the stirrer antenna holder).
Refer to Figure C-9.
2. Set the direction of the stirrer antenna and antenna holder so that
the hole of the antenna holder fit to the centre of the stirrer
antenna's big blade. Refer to Figure C-9.
3. Hook the hole of the antenna holder on the tab of the oven cavity
bottom plate. Refer to Figure C-10.
4. Insert the antenna holder into the hole of the oven cavity bottom
plate and fit the hole of the antenna holder with an antenna motor
shaft. Refer to Figure C-10.
5. Install the antenna holder to the oven cavity bottom plate with the
one (1) screw and the one (1) washer. Refer to Figure C-8.
6. Install the antenna motor to the oven cavity bottom plate with one
(1) screw. Refer to Figure C-8.
7. Connect the wire leads to the antenna motor, referring to the picto-
rial diagram.
8. Install the base plate cover to the base plate with one (1) screw.
9. Install the ceramic shelf to the oven cavity bottom plate. Refer to
"INSTALLATION OF CERAMIC SHELF".

[16] INSTALLATION OF CERAMIC SHELF
1. Disconnect the power supply cord.
2. Open the door and block it open.
3. Make sure that the smooth surface of the ceramic shelf face up.
4. Make sure that the rubber packing without a fin of the ceramic shelf
faces the front of the oven.
NOTE: The three (3) rubber packings with the fins and the one (1)
rubber packing without a fin are attached to the four (4) edges
of the ceramic shelf. The one (1) rubber packing without a fin
is the front edge of the ceramic shelf.
5. Put the front edge of the ceramic shelf into the front edge of the
oven cavity bottom plate.
