Microphone Operation: microphone transparent casing anti-clockwise rotation, according to the correct polarity direction into two AAA 1.5V batteries, then clockwise direction in a transparent shell into the microphone body, then the correct whip Microphone-shaped antenna into the rear will be placed switch "ON" position, this indicator can be turned into the working conditions (see the following section LED display 4:00 note), a blue and red microphone signals corresponding receiver blue (CH1) and red (CH2) frequency of the LED. 2. Receiver operating (PSIII game configuration): receiver open the battery cover in the correct polarity direction into a 9 V battery, and then wiring in the annex to insert the PS3 converter input socket on the other end Insert the receiver 3.5 standard audio sockets, switches will be placed in the "ON" position, then the receiver power indicator light, said that the receiver can start work and receiving signals transmitted from the microphone, the microphone signal received the corresponding channel signal LED also brightened, the game will be necessary at this time the menu should be elected position of the corresponding game programs, all on Syria before the game with the singer in a song contest. 3. Receiver operating (OK amp karaoke machine configuration): receiver open the battery cover in the correct polarity direction into a 9 V battery, and then in the annex to the cable and connector insertion karaoke machine OK AMPLIFICATION The audio input socket, it will switch at the "ON" position, then the receiver power indicator light, said that the receiver can start work and receiving signals transmitted from the microphone, amplifier of this will be the volume of spin and MIC IN Button placed third position, and power amplifier-player and display device should be connected to normal, after all the display equipment can be OK singing karaoke. 4. LED Display: will be placed microphone switch "ON" position, one of a lit LED 3 seconds, and then cycle three LED flashes when the microphone without audio signals (stop singing) more than three minutes to cease flashing , this LED is only a faint light, complete machine into the power-saving mode. If a microphone audio signal (to sing), flashing LED automatic entry into the cycle. 5. Other features: a microphone and receiver with automatic protection devices and power-saving mode, when no microphone audio signals (stop singing) over one minute, the microphone signal will automatically stop firing into the protection of the state, at the same time open the MCU power-saving mode, receiver has entered fully power-saving mode. For the process of singing suspended singing, and do not want to pick up the microphone to other sounds, the game can handle the Pause button.

Please correct installation of battery, pay attention to positive and negative polarity. 2.When the microphone is noise or receive shorter distance, should be replaced microphone and receiver battery. 3. Please correct use of microphones, not to throw, throw, throw, it will seriously damage the engine, the protection of the surface of the transparent microphone. 4. If the distance is too great, and the noise generated rustle that exceeded the scope of services, return to the acceptable range. 5. After use, such as no longer to be sure demolition battery, battery to avoid metamorphic fluid, mechanical damage. 6. Host advised to avoid using on a corner, in order to maintain good signal reception. 7. Body should avoid direct sun or rain, as far as possible from high electromagnetic fields. 8. Please do not open without the engine, if fault, please contact …

CIRCUIT DESCRIPTIONS The wireless microphone uses a transmitter module operation in the VHF band. This modulator is a high performance, nine channel FM transmitters capable of transmitting analog data. To transmit analog information the moduler reverts to FM modulation. An 60.0MHz FM oscillation serves as the base frequency reference for the Phase Locked Loop (PLL), supporting the one time and two time frequency for give and high frequency. The PLL combined with a 174-216MHz VCO, forms a stable frequency synthesizer that can programmed to oscillate at a number of present frequencies. An onboard micro-controller reads the channel-selection lines and programs the PLL to desired channel frequency. A buffer amplifier is used to isolate the VCO from the antenna and to increase the output power of the transmitter. The output of amplifier is connected to a BPF which used to suppress harmonics emissions.
