Applicant: ARRAY ELECTRONIC CO., LTD. FCC ID: TOFAUH210 Operation Description 1. Audio 1). MIC AMP (U 1 ) 2). Regulator (U 4 ) BATT (1.5V) 2. RF 1). Q 5 is the oscillation circuit. This controls the transmitting frequency to the buffer amplifier (Q 2 , Q 6 ) via PLL (U 6 ). Q 3 This multiplies the frequency oscillated from Q 2 , Q 6 . Q 4 This multiplies the frequency oscillated from Q 3 . The frequency from Q 3 will be sent out to the antenna via the bandpass filter. 2). U 3 is the infrared receiving units, which control PLL (U 6 ) to change the frequency of the transmitter via CPU (U 2 ) when receiving the infrared signal. 3). U 5 is the EEPROM, which is used to save the data of the frequency of the transmitter.
