conjunction with any other antenna or transmitter.
NOTE:
This equipment has been tested and found to comply with
the limits for a Class B digital device, pursuant to part 15 of the
FCC CERTIFICATION
FCC Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate
radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interfer-
ence to radio communications. There is no guarantee that
interference will not occur in a particular installation. If this
equipment does cause harmful interference to radio or
television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following
MEASURES:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and
receiver.
- Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician
for help.

Tips and Methods to Improve Wireless System Performance
1) Keep more than 3 meteres distance between Receiver
unit and other WiFi transmitters such as routers.
2) Change channels to avoid interference with other WiFi
products.
3) In case of environmental interference from other WiFi
systems, shorten the distance between the receiver and
transmitter units.

2.4Ghz Frequency Tables
U3C operates within the 2.4GHz ISM band which is utilized
by Wi-Fi, Bluetooth, and other wireless devices. 2.4GHz is
an open band and, as such, does not require a license to be
used worldwide.
* U2 1~4 channels are the same as U3/U3C 1~4 channels,
U2 and U3/U3C use in sametime max is 6 sets.

TROUBLESHOOTING
ISSUE
• Check that the Receiver's RF LED is lit.
• Check that the microphone is turned on and receiving signal from the U3C Transmitter.
• Check that the power switch is turned on for both the Transmitter and the Receiver.
• Ensure that the U3C Transmitter and Receiver are on the same channel.
• U3C will provide 12V or 48V phantom power to condenser microphone.
Please select your microphone phantom power volts.
• If used in dynamic microphone, the current consumption will be the same as that of a
condenser microphone.
• The receiver can be paired with one Transmitter at a time.
• If you connect the device with a receiver, check if the device is balanced XLR interface
• See, “Tips and methods to improve wireless system performance” page 12
• The channel switch locks after 15 seconds. Double-click the channel button to unlock and reset.
• Use one transmitter can connect with more than 2 receivers.
• Never plug single-ended (unbalanced) or dynamic microphones into U3C,
can be permanently damaged if phantom power is applied to them.
