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 authority to operate the device. 1. Introduction Thank you for purchasing our product.  This wireless microphone system operates in UHF band frequency with synthesizer controlled.  Each 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 an audio mixer or an amplifier. (Refer to 7.2) 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.

Setting Up NOTICE:  Prior to setting up, check that the transmitter and receiver are tuned to the same frequency.  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 Ø  Plug the antennas into the TNC socket on the receiver, if the antennas are detachable and point them upward. Ø  Check that the voltage of the supplied AC adapter conforms to the voltage (AC110 or 220) available 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. 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 volume level according to following instructions.  Ø When using a standard audio cable with 3-pin XLR connectors or 6.3j phone plugs to plug into the MIC IN on the audio mixer or on the amplifier, please turn the Volume Level Control on the receiver to around 1 o’clock position, the output level for balanced and unbalanced output is about at 77mV.  Ø When using a standard audio cable with 3-pin XLR connectors or 6.3j phone plugs to plug into the LINE IN on the audio mixer, please turn the Volume Level Control to around MAX. on the receiver position, the output level for balanced and unbalanced output is about at 770mV. Ø When the MIXING switch is in the OFF position, the XLR output for channels 1 and 2 are separate.  When the MIXING switch is in the ON position, the XLR output for channels 1 and 2 are mixed, so that both XLR outputs have combined signal from both channel 1 and channel 2. 7.3 Inserting batteries into the handheld microphone / bodypack transmitter 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 stays 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 Close the battery cover.  Never use the balanced and unbalanced audio outputs at the same time!  This may cause signal loss or increased noise. Wireless Microphone  15

Ø When using 2 or above microphone sets simultaneously, make sure that the chosen frequencies are not interfered.  Ø  Check whether the interference comes from other wireless microphones, TV, radio and etc. Distortion    Ø  Check the gain control (Mic Adj.) for bodypack transmitter is set too high or too low.  Ø Check whether the interference comes from other wireless microphones, TV, radio and etc.  7.4 Setting up the handheld microphone transmitter Ø  Switch the receiver power on and check the frequency and volume level.   Ø  Switch the transmitter and hi-fi appliance (amplifier, tape deck etc.) power on. Ø Test the microphone and adjust the levels on your audio mixer or amplifier. 7.5 Setting up the bodypack transmitter A. Connecting a microphone Ø  Open the battery cover.  Push the MIC/LINE switch to “MIC” and use the supplied screwdriver to adjust the GAIN (MIC Adj.) at appropriate position. Ø Plug the mini XLR connector of the microphone cable into the audio input connector on the bodypack transmitter. Ø Switch the transmitter and hi-fi appliance (amplifier, tape deck etc.) power on. Ø Test the microphone and adjust the levels on your audio mixer or amplifier. B. Connecting an instrument Ø Open the battery cover.  Push the MIC/LINE switch to “LINE” and use the supplied screwdriver to adjust the GAIN (MIC Adj.) at appropriate position. Ø Plug the 6.3j phone plug of the optional guitar cable to the output jack on the instrument and the mini XLR into audio input connector on the bodypack transmitter.
