transceiver, and the three along the top edge of
the rear panel, then lift off the top cover.

the transceiver, then lift off the bottom cover.
Locate the REF UNIT in the front right corner of
the chassis (see photo on previous page), and
remove the wiring connector from the board.
Use a small screwdriver to pry up the rear edge
of the connector, and avoid pulling on the wires.

board, and remove the REF UNIT.

same screws just removed to affix the new
board in place. Reinstall the wiring connector.

cover and screws removed above (unless in-
stalling other options now).
Main Receiver 2nd and 3rd IF Filters
A total of 5 optional crystal IF filter units can be
installed in addition to the factory-installed filters
(see the table at the top of the next column for
filter part number and bandwidth. Contact your
dealer for pricing, availability and ordering. These
filters include small boards with connectors, so no
soldering is necessary for their installation.
03> Important! After filter installation, front-panel
selection is not possible until individual filters are
enabled via menu programming (menus 5-0 ~
5-8). Refer to the Menu Programming chapter and
enable the optional filters after installing them.

its mounting position is also exposed during the
optional filter installation procedure.
Filter Installation
© Disconnect all cables from the transceiver.
1 Remove the three screws on each side of the
transceiver, and the three along the top edge of
the rear panel, then lift off the top cover.
(1 Remove the seven screws from the bottom of
the transceiver, then lift off the bottom cover.
[On the underside of the transceiver chassis,
locate the IF UNIT. Referring to the photograph
below, determine the location of the filter(s) you
are installing.
Position each filter so that its connectors are
aligned with the mounting pins on the board,
and push it into place, so the nylon mounting
tabs "mushroom" through the holes and lock
the unit in place.
Replace the bottom and top cover (unless in-
stalling other options now). Refer to page 89 of
the Menu Programming chapter to enable
newly-installed filters.
