Tips and Methods to improve the performance
of the wireless system
1) Keep more than 3 meters distance between the U3
receiver and other transmitters such as Wi-Fi routers.
2) If you experience interference from Wi-Fi devices in the
vicinity, try changing to a dierent channel on the U3
transmitter and receiver.
3) If necessary, shorten the distance between the U3
receiver and transmitter.

2.4 Ghz Frequency Tables
The U3 operates in the 2.4 GHz ISM band, the same band
used by Wi-Fi, Bluetooth, and other wireless systems. 2.4 GHz
is an open band and as such does not require a license to
operate worldwide.
U2 channels 1-4 use the same frequencies as U3/U3C/U4
channels 1-4. A maximum of six U2/U3/U3C and U4 sets
can be used at the same time.

ISSUE
• Check that the U3 Receiver's RF LED is lit.
• Check that the microphone is turned on and that you receive a signal from the U3 transmitter.
• Check that the power switch is turned on for both the Transmitter and the Receiver.
• Ensure that the U3 Transmitter and Receiver are on the same channel.
• The Receiver can only be paired with one Transmitter at a time.
• Switch the gain mode to “Line” or “Mic”
• Adjust the output signal from the transmitting device.
• See, “Tips and methods to improve wireless system performance” page 15
• The channel switch locks after 15 seconds. Double-click the channel button to unlock and reset.
• One transmitter can be used with multiple receivers on the same channel.
SOLUTION
