Introduction Thank you for purchasing our product. This wireless microphone system operates in VHF band frequency with crystal controlled. 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 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. FEATURES & SPECIFICATIONS WIRELESS 9. System Feature

Use the supplied screwdriver to adjust the GAIN at appropriate position.
Plug the 3.5 plug of the microphone cable into the audio input jack on the bodypack transmitter.
Switch the transmitter and hi-fi appliance (amplifier, tape deck etc.) power on.
Test the microphone and adjust the levels on your audio mixer or amplifier. 7.5.2 Connecting an instrument
Use the supplied screwdriver to adjust the GAIN at appropriate position.
Plug the 6.3 phone plug of the optional guitar cable to the output jack on the instrument and the 3.5 plug into audio input connector on the bodypack transmitter.
Switch the transmitter and hi-fi appliance (amplifier, tape deck etc.) power on.
Play the instrument for testing and adjust the levels on your audio mixer or amplifier. 8. Troubleshooting
Before 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. If undesirable noise occurs, adjust the SQUELCH control on receiver in clockwise to suppress it. The higher squelch control, the lower the sensitivity of the receiver and decrease the service area of the system.
Problem No sound Solution
Check the power supply of the microphone and receiver.
Check that the transmitter and receiver are using same frequency.
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. Distortion 9
When using 2 or above microphone sets simultaneously, make sure that the chosen frequencies are not interfered.
Check whether the interference comes from other wireless microphones, TV, radio and etc.
Check the gain control (Mic Adj.) for bodypack transmitter is set too high or too low.
Check whether the interference comes from other wireless microphones, TV, radio and etc. WIRELESS NOTE WIRELESS 5.

Two or above transmitters operating in the same frequency can not be 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
Point the antennas upward.
Check that the voltage of the supplied AC adapter conforms the output DC 12V in local area. Using the wrong AC adapter may cause irreparable damage to the unit.
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. 7.2 Connecting the receiver to an audio mixer or an amplifier In order to make sure the sound quality and avoid distortion, please adjust the MIC/LINE switch according to following instructions.
When using a standard audio cable with XLR or 6.3 phone plugs to plug into the MIC IN on the audio mixer or on the amplifier, please select the MIC/LINE switch to MIC position, the output level for unbalanced output is about at 100mV.
When using a standard audio cable with XLR or 6.3 phone plugs to plug into the LINE IN on the mixer, please select the MIC/LINE switch to LINE position, the output level for unbalanced output is about at 1V. 7.3 Inserting batteries into the handheld microphone / bodypack transmitter
