FCC Statement
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
Notice : The changes or modifications not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
IMPORTANT NOTE: To comply with the FCC RF exposure compliance requirements, no
change to the antenna or the device is permitted. Any change to the antenna or the device
could result in the device exceeding the RF exposure requirements and void user’s authorit
y
to operate the device.
1. Introduction
Thank you for purchasing our product. This PLL synthesized wireless microphone system
operates in UHF band frequency with 15 or 16 selectable channels. Please read this
instruction manual carefully before operating the system. This manual covers the function
and operation of the wireless microphone system.
2. Safety
 Do not spill liquid on the appliance and do not drop it on a hard concrete floor.
 Do not place the appliance near heat sources such as radiators, amplifier, or etc.
 Do not expose it to direct sunlight, extremely dust, excessive moisture, or vibration.
 Take out the battery from transmitter, if the appliance has been not used for a longer
period. This will avoid the damage resulting from a defective leaking battery.
3. Environment
 Do not throw used batteries into a fire or garbage bin with domestic rubbish. Be sure to
dispose of used batteries in accordance with local waste disposal rules.
 When disposing the equipment, remove the batteries, separate the case, circuit boards,
and cables, and dispose of all components in accordance with local waste disposal rules.
4. Wireless Note

Before setting up, make sure that the transmitter and receiver are tuned to the same
frequency.
 Do not use two transmitters in the same frequency.
 Use good quality batteries to avoid the damage resulting from a defective leaking battery.
 Turn the MIC/LINE switch on the rear of receiver to adjust receiver output level to match
input level requirements of an audio mixer or amplifier.
 While checking sound, move the transmitter around the area where you use the system to
look for dead spots. If you find any dead spot, change the receiver position. If it does
not work, avoid such places.
 To avoid interference, do not put the receiver too near metal object and avoid obstructions
between transmitter and receiver.
 Avoid the interference from TV, radio, other wireless appliances and etc.
9. System Feature

Operating in UHF band frequency with synthesizer controlled.

The wireless microphone system with 16 selectable frequencies via Phase Locked Loop (PLL)
circuitry makes it easy to choose non-interfered channels.

Diversity with two antennas to ensure the reception quality.

Super high sensitivity, extremely low noise transmission and reception.

SMT assembled PCB module ensures the quality and stability.
