Introduction Thank you for purchasing our product. This wireless microphone system operates in UHF band frequency with synthesizer controlled. The system w ith 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
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 volume control on the receiver to adjust receiver output level to match input level requirements of a mixer or amplifier. Please see 7.2
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. Wireless Microphone 1 WIRELESS PRODUCT DESCRIPTION 5.

Check whether the hi-fi appliance is switched on and the receiver output is connected to audio mixer or amplifier input.
Check whether transmitter is too far away from receiver or SQUELCH control set too high.
Check whether receiver is located too near metal object or there are obstructions between transmitter and receiver. Sound interference Check the antenna location.
When using 2 or above microphone sets simultaneously, make sure that the chosen frequencies are not interfered. Distortion 8
Check whether the interference comes from other wireless microphones, TV, radio and etc.
Check the receiver volume level is set too high or too low.
