O3U630174RXWireless Audio Player

#630174 Real Heroes Shuttle Commander W/CD Technical Description The product consists of 2 parts, the transmitter unit and receiver unit. The transmitter unit is connected to the music player (“walkman” or “discman”) to accept audio music, and send the music to the receiver unit via the RF channel. The receiver unit demodulate the RF signal from the transmitter unit, and output to the speaker. The transmitter unit is operated with 4 x 1.5V AAA battery cells. When the transmitter unit is powered on and connected to the music player (“walkman” or “discman”), The transmitter unit will modulate the audio music with the carrier signal (107.7MHz), and send out the mixed signal (carrier signal and audio music) via the antenna. The signal is emitted continuously while the transmitter unit is powered on. The receiver unit is either operated with 3 x 1.5V AAA battery cells. When the power switch is turned on, the unit is ready to receive the RF signal. If the transmitter unit is powered on and connected to the music player, there will be a RF signal output from the antenna of the transmitter unit. The receiver unit will receive the RF signal, and recover the original music by means of demodulation. At last the audio music is output to the speaker.

Frequency Alignment Procedure of #630174 Real Shuttle Commander 1.Transmitter a)Connect the transmitter unit to the DC power supply (+6VDC); b)Use the Spectrum Analyzer to monitor the frequency; c)Adjust the coil L5 on the PCB unit the frequency reading on the Spectrum Analyzer is 107.7MHz +/-0.05MHz; d)Use the wax to seal and fix the coil L5. 2.Receiver a)Connect the receiver unit to the DC power supply (+4.5VDC); b)Use the Sweep Generator to generate a RF signal of 107.7MHz, and connect the speaker output of the receiver unit to the input of the Sweep Generator, there will be a “S” curve display on the Sweep Generator c)Adjust the coil L1 to align the center point of the “S” curve on the Sweep Generator to the frequency point of 107.7MHz +/- 0.1MHz; d)Use the wax to seal and fix the coil L1.
