1. Introduction
Thank you for purchasing our product. This wireless microphone system operates in UHF
band frequency with synthesizer controlled. The system with 16 or 64 selectable frequencies
via Phase Locked Loop (PLL) circuitry makes it easy to choose non-interfered 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
Ø Do not spill liquid on the appliance and do not drop it on a hard concrete floor.
Ø 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.
Ø 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
Ø 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.
Ø 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
Ø Before setting up, make sure that the transmitter and receiver are tuned to the same
frequency.
Ø Do not use two transmitters in the same frequency.
Ø Use good quality batteries to avoid the damage resulting from a defective leaking battery.
Ø Turn the volume control on the receiver to adjust receiver output level to match input level
requirements of a mixer or amplifier.（Please see 7.2）
Ø 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.
Ø To avoid interference, do not put the receiver too near metal object and avoid obstructions
between transmitter and receiver.
Ø Avoid the interference from TV, radio, other wireless appliances and etc.

11. Unbalanced Output: 6.3j phone jack provides unbalanced low-impedance output
12. Squelch: The squelch adjusts the output level to suppress the noise. Setting the squelch
too high will reduce the usable range of the system. Set the squelch to minimum before
turning the receiver on.
13. DC IN: Input connector for the supplied AC adapter.
14. Charger Input: Connect the supplied cable to the receiver and the microphone, and it
takes around 10 hours to recharge and the LED of transmitter is flashing all the time.
15. Coil Strain: For the feeder cable of the supplied AC adapter.

flashing once indicates that the transmitter has sufficient power. If the LED stayed on, it
indicates that the battery has insufficient power and should be changed soon. If the status
LED fails to flash, the battery is either dead or not positioned correctly, and you should correct
the positioning or change the battery.
3. On/off Switch: Turns transmitter power on and off.
4. Battery Compartment: Insert two AA dry or rechargeable batteries into the compartment
and make sure that the polarity of batteries is correct.
5. Group Selector: Changes transmitter Group setting.
6. Channel Selector: Changes transmitter Channel setting.

used at the same time and area, so please select the different frequencies which can
be used simultaneously at local area.
7.1 Connecting the receiver to power
Ø Plug the antennas into the TNC socket on the receiver and point them upward.
Ø Check that the voltage of the supplied AC adapter conforms to the voltage available (AC110 or
220) in local area. Using the wrong AC adapter may cause irreparable damage to the unit.
Ø Plug the feeder cable of the supplied AC adapter into DC IN socket on the receiver. Then
plug the AC adapter into a power outlet.

Ø Push to open the battery cover and insert batteries into the battery compartment conforming to
the polarity (+)(-) marks. The transmitter can not work with incorrectly inserted batteries.
Ø When push the ON/OFF switch to “ON” to switch the power on, the LED will flash momentarily.
If the battery has sufficient power, the LED flashes once. If the LED stayed on, it indicates
that the battery has insufficient power and should be changed soon. If the status LED fails to
flash, the battery is either dead or not positioned correctly, and you should correct the
positioning or change the battery.
Ø Push back the battery cover to click it shut.
7.4 Setting up the handheld transmitter

8. Trouble-shooting
Problem Solution
No sound äCheck the power supply of the microphone and receiver.
äCheck that the transmitter and receiver are tuned to the same
frequency.
äCheck whether the hi-fi appliance is switched on and the receiver
output is connected to audio mixer or amplifier input.
äCheck whether transmitter is too far away from receiver or SQUELCH
control set too high.
äCheck whether receiver is located too near metal object or there are
obstructions between transmitter and receiver.
Sound interference äCheck the antenna location.
äWhen using 2 or above microphone sets simultaneously, make sure
that the chosen frequencies are not interfered.
äCheck whether the interference comes from other wireless
microphones, TV, radio and etc.
Distortion äCheck the receiver volume level is set too high or too low.
äCheck whether the interference comes from other wireless
microphones, TV, radio and etc.
