• Do not expose to moisture.
• Switch rechargeable battery-powered products off after use.
• Only charge rechargeable batteries at ambient temperatures between 10^ / 50^ and 40^ / 104^ .
• When not using rechargeable batteries for extended periods of time, charge them regularly (about every three months).

• Do not mutilate or dismantle.

• Do not heat above 60^ / 140^ , e.g. do not expose to sunlight or throw into a fire.

• Immediately remove rechargeable batteries from obviously defective products.
• Do not continue to use defective rechargeable batteries.
• Only use rechargeable batteries specified by Xvive.
• Dispose of rechargeable batteries at special collection points or return them to your specialist dealer.
• Store the products in a cool and dry place at room temperature (approx. 20^ / 68^ ).
• Remove the rechargeable batteries if the products will not be used for extended periods of time.

Note:

Turn off the power switch while charging.

Please do not use the U3 when charging.

This may reduce battery life.

2.4 GHz WIRELESS OVERVIEW AND INTERFERENCE

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.

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 different channel on the U3 transmitter and receiver.
3) If necessary, shorten the distance between the U3 receiver and transmitter.

2.4 Ghz Frequency Tables

CHANNEL 1	2402 MHz, 2480 MHz, 2482 MHz
CHANNEL 2	2408 MHz, 2472 MHz, 2474 MHz
CHANNEL 3	2416 MHz, 2464 MHz, 2466 MHz
CHANNEL 4	2434 MHz, 2440 MHz, 2442 MHz
CHANNEL 5	2427 MHz, 2448 MHz, 2450 MHz
CHANNEL 6	2422 MHz, 2456 MHz, 2458 MHz

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.

TROUBLESHOOTING

ISSUE	SOLUTION
No sound	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.
Distortion or weak sound	Switch the gain mode to "Line" or "Mic"Adjust the output signal from the transmitting device.
Signal instability: RF LED flickering, or off completely	See, "Tips and methods to improve wireless system performance" page 15
Unable to switch the channel	The channel switch locks after 15 seconds. Double-click the channel button to unlock and reset.
Multiple connect	One transmitter can be used with multiple receivers on the same channel.
