Applicant: ARRAY ELECTRONIC CO., LTD. FCC ID: TOFAUT210 Operation Description 1. Audio 1). MIC AMP (U 1 ) This amplifies the voice signal of 50Hz¬15KHz by about 20dB and makes pre-emphasis features of 50us. 2). Regulator (U 6 ) This makes standard voltage for MIC AMP and RF part being supplied power from 3.0V battery. 2. RF 1). Q 4 is the oscillation circuit. This controls the transmitting frequency via PLL (U 5 ). The frequency is through the buffer amplifier (Q 1 , Q 5 ) then to the first frequency amplifier Q 2 then to the second frequency amplifier Q 3 and finally be sent out to the antenna via the bandpass filter. 2). U 3 is the infrared receiving units, which control PLL (U 5 ) to change the frequency of the transmitter via CPU (U 2 ) when receiving the infrared signal. 3). U 4 is the EEPROM, which is used to save the data of the frequency of the transmitter.
