Here is a good set-up procedure grom Shure --

1. Turn the transmitter power off to eliminate the desired signal.
2. Turn on all associated equipment in nearby locations to create the "worst-case" signal condition.
3. Set the receiver volume control to minimum to avoid excessive noise in the sound system.
4. Turn the receiver power on.
5. Observe the RF and audio indicators on the receiver.
6. If the indicators are showing a no-signal condition the squelch setting may be left as-is.
7. If the indicators are showing a steady or intermittent signal-received condition increase the squelch control setting until a no-signal condition is indicated. Set the squelch control slightly past this point to provide a threshold margin.
8. If the no-signal condition cannot be achieved even with high squelch settings it may be possible to find and eliminate the undesirable signal. Otherwise it may be necessary to select a different operating frequency.
9. Turn the transmitter power on.
10. Make sure that the receiver indicates a signal-received condition with the transmitter at normal operating distance. Remember that high squelch settings reduce the operating distance.

Now go forth and be wireless --
