the list below. Then press Apply and Save. This will save changes and open the
QAM List window.
Note: If you experience signal interference, try offsetting your BFS QAM output
frequency by 250 KHz from the one you have chosen.

7 Repeat steps 1-6 for the other BFS QAMs on your system.
Reboot the BFS QAM and Verify Counts
Note: At this point in the process, the QAM List window should be open. If it is not,
retrace the steps you have taken and complete any that were omitted.
1 At the QAM List window, select the BFS QAM that you changed.
2 To reset this BFS QAM, click File/Reset. Resetting the device applies the
1 At the QAM List window, select the BFS QAM that you changed.
2 To reset this BFS QAM, click File/Reset. Resetting the device applies the
changes you made to the BFS QAM, which then begins transmitting on the
unique frequency you entered previously.
3 At the BFS QAM front panel, verify that the session and program counts match
the values you recorded earlier (see Change the BFS QAM Output Frequency (on
page 2)).
Note: If the counts at the BFS QAM front panel do not match the recorded
values, stop and refer the matter to Cisco Services.
