Appendix C.
7 DOWNLINK OPTION
This appendix describes the 7 downlink option installed in the SMS-758.
Operation of the switch is basically the same as in 4 downlink/2 backup mode, except that
only one backup is used.
Refer to Appendixes A and B for remote control information.
Enclosed is a rear panel sticker for the 7 downlink option that displays the proper rear panel
connectors and J-numbers.
To install the 7 downlink sticker:
1. Remove the 10 nuts from the downlink inputs and backup demod outputs.
2. Wipe down the rear panel around the downlink inputs to remove any loose dirt.
3. Remove the backing from the sticker.
4. Place the sticker as shown in Figure 2-1, being sure to smooth out any air
bubbles.
5. Replace the 10 nuts on the BNC connectors, being careful not to damage the
sticker.
