CERTIFICATION

210-135155

THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES.

OPERATION IS SUBJECT TO THE FOLLOWING TWO

CONDITIONS: (1) THIS DEVICE MAY NOT CAUSE HARMFUL

INTERFERENCE, AND (2) THIS DEVICE MUST ACCEPT ANY

INTERFERENCE RECEIVED, INCLUDING INTERFERENCE

THAT MAY CAUSE UNDESIRED OPERATION.

WARNING:

Changes or modiﬁcations not expressly approved in

writing by Xvive may void the users authority to operate

this equipment.

RF EXPOSURE STATEMENT:

This transmitter must not be co-located or operated in

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 Rules. These limits are designed to provide

FCC CERTIFICATION

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 interference 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.

1. Observe all instructions carefully in the U4 set manual.

2. Do not to perform service operations beyond those

described in the U4 set manual. Services required when

the apparatus has been damaged in any way, such as:

• Liquid has been spilled or objects have fallen into the

apparatus

• The unit has been exposed to rain or moisture

• The unit does not operate normally or changes in

performance in a signiﬁcant way

• The unit is dropped or the enclosure is damaged

WARNING: BEFORE USING YOUR XVIVE U4 MICROPHONE WIRELESS SYSTEM,

CAREFULLY READ THE OPERATING INSTRUCTIONS.

IMPORTANT SAFETY INSTRUCTIONS

PLEASE READ THESE INSTRUCTIONS IN A SAFE PLACE

3. Do not place near heat sources, such as radiators, heat

registers, or appliances which produce heat.

4. Guard against objects or liquids entering the device.

Do not use or place unit near water.

5. Clean only with a dry cloth.

6. Only use attachments/accessories speciﬁed by the

manufacturer.

7. Prolonged listening at high volume levels may cause

irreparable hearing loss and/or damage. Always be sure

to practice “safe listening.”

LISTENING TO AUDIO AT EXCESSIVE VOLUMES CAN

CAUSE PERMANENT HEARING DAMAGE. USE AS LOW

A VOLUME AS POSSIBLE.

Over exposure to excessive sound levels can damage

your ears resulting in permanent noise-induced

hearing loss. Do not use earphones for a long time

and set the volume below 70% or lower.

U4 person wireless monitoring system provides better

sound feedback for stage performers and performance

quality. As a portable wireless system, you don't need to

set up. Just plug-and-play to quickly build your monitor-

ing system.

FEATURES:

• 2.4Ghz wireless In-ear monitor system

• Solid RF connection over a 90 feet range(actual range

depends on RF signal absorption, reﬂection and

interference)

• Up to 107 dB signal-to-noise ratio provides clear, detailed

audio at any volume.

• High Resolution 24-bit/48kbps audio

• Broad 20Hz-20KHz frequency response

• Dynamic Rang 107 dB

• Less than 5ms Latency, Simultaneous broadcasts on 6

channels.

• 5 Hours of battery life ( rechargeable battery for both

Transmitter & Receiver )

• Provides smooth frequency response with any headphones

• Mono balanced XLR or mono unbalanced TS input

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

U4 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/U4 1~4 channels,

U2, U3/U3C and U4 use in sametime max is 6 sets.

Unable to switch the channel

Multiple connect

• Check that the U4 Receiver's RF LED is lit.

• Check whether the device has a signal sent to the transmitter

• Check that the power switch is turned on for both the Transmitter and

the Receiver.

• Ensure that the U4 Transmitter and Receiver are on the same channel.

• The Receiver can be paired with one Transmitter at a time

• Check the Line/Aux setting at the transmitter and verify that the meter is not

reaching the overload

• Check Levels going in and out of the mixer. Verify that no distortion occurs in

each audio signal.

• Check receiver headphone output Volume level

• Check Transmitter mode Line/Aux.

• Check Check whether the device has enough signals level to the transmitter.

• See, “Tips and methods to improve wireless system performance page 13

• 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.
