Carefully push down on the fIlter to insert the pins into the sockets. Relatively light
pressure is required to insert the pins into the sockets. If the fIlter does not easily
slide into place, recheck the pin/socket alignments.
3. Insert the appropriate fIlters into fIlter positions FL2 through FL 7 (as required), uslng
the procedures described in steps 1 and 2.
4. After all filters have been inserted, visually inspect the fllters to insure that they are
properly seated. The bottom of the fIlters should be flat against the surface of the
A4 board.
5. Replace the RF shield over the fIlters and secure the shield in place by tightening the
three screws.
NOTE
If the Receiver is to be equipped for operation from a remote control device
or in the ISB mode, continue with the procedures described in Paragraphs
2-8
