FCC warning statement
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 74
of the FCC Rules. These limits are designed to provide reasonable protection againstharmful interference in a
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. However, 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.
Caution: Any changes or modifications to this device not explicitly approved by manufacturer could void your authority to
operate this equipment.
This device complies with part 74 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.

①EIA-standard metal 1U - rack receiver chassis, antenna diversity.
②Bright and easy-to-read LCD display shows RF/AF, diversity strengths; transmitter battery level;
meanwhile, can set up selective channel, frequency, mute and other working status.
③Press the "AFS"(Auto Frequency Selection) button 3S and the receiver will auto-scan and lock on
to an open, interference-free frequency
④Press [IR] button to upload automatically the receiver frequency to the transmitter.
⑤PLL (Phase Lock Loop frequency control) design ensures transmission reliability, "NoiseLock"
squelch effectively blocks stray RF.
⑥Each channel 32 selectable frequencies, dual- channel total 768 selectable frequencies
Introduction
Installation:
①For better operation the receiver should be at least 3ft. 1m above the ground and at least 3ft.
away from a wall or metal surface to minimize reflections.
②Attached a pair of UHF antennas to the antenna input jacks, the antenna are normally positioned in the
shape of a “V” (both 45°from vertical) for best reception.
③Keep antennas away from noise sources such as computer, digital equipment, motors, automobiles
and neon lights, as well as away from large metal objects.
④Keep open space between the receiver and transmitter for better reception.
⑤The transmitter should be at least 3ft. from the receiver.
Connections:
①The switching power supply is designed to operate properly from any AC power source 100-240V,
50/60Hz without user adjustment. Simply connect the receiver to a standard AC power outlet, using only
an IEC-type input cordset approved for the country use. Power to the unit is controlled by the front panel
power switch.
②There are two audio outputs on the rear panel: an XLR microphone output and a 1/4” (6.3mm) phone
jack instrument output. The two isolated audio outputs permit simultaneous feeds to two different
inputs. Use the appropriate shielded audio cable for connections between the receiver and the
input (s) of the mixer or other equipment.

①Turn down the AF level of the associated mixer or amplifier, and make sure that any transmitters are
turned off.
②Turn on the receiver, the LCD displays the preset data.
③To change the frequency by manual or “AFS” (Auto Frequency Scan).
a, Touch ﹤/﹥ button once to select a new frequency.
b, Press and hold ﹤/﹥button 3 seconds and the receiver will auto-scan and lock on to an open,
interference-free frequency.
NOTE: After selecting a new frequency, let the transmitter IR receiving window face to the receiver IR data
transfer window, then press “SYNC” button, the transmitter will receive the frequency / channel dada from
the receiver, simultaneously the LCD displays the same frequency / channel as the receiver (Figure C).
