SOLUTION
• Make sure that the U3 Transmitter and Receiver are set to the same channel.
• Check that the U3 Receiver's RF LED is on.
• Check that the microphone is properly connected to the U3 Transmitter, and turned on if necessary
• Check that the Transmitter and Receiver power switches are both turned on.
• Note: Receivers can be paired with only one Transmitter at a time.
• Make sure the input/gain mode is correctly set to "Line"
(for an audio device such as a mixer) or "Mic" (for a microphone).
• Adjust the output signal from the transmitting device (turn up if too faint, turn down if distorting)
• See "Tips and methods to improve wireless system performance" on page 17
• The channel switch locks after 15 seconds. Double-click the channel button to unlock and reset.
• One transmitter can connect with two or more receivers;
but receivers can only accept signal from one transmitter.
