FCC ID: HAP8835T9 Model No: 8835 CIRCUIT DESCRIPTION In transmit push IC input pin F,B,L and R key ,Output of IC pin 8 drives Q2,output of Q2 drives the transformer L3,Which modulates the crystal 49.860Mhz controlled oscillator Q1. This oscillator is the transmitter. The antenna is transformer coupled to the oscillator. In receive L1 turning 49.860Mhz frequency And Q1 are RF amplifier and detector stages. IC control receiver signal to output pin F,B,L and R. Q10 ,Q11 and Q2,Q3 to driver Q12,Q13,Q14,Q15 and Q4,Q5,Q6,Q7 become driving the motor. ANTENNA AND GROUND CIRCUITRY This unit makes use of an external flexible 38 centimeters long antenna. The antenna is inductively coupled. The unit relies on the ground tract of the printed circuit board. No external ground is provided. Energy is supplied by a 9-volt battery.

Measurement facility: Measurement facility located at Fanling (Hong Kong), placed on file with the FCC Pursuant to Section 2.948 of the FCC Rules. 2. Distance between the EUT and measuring antenna: 3 meters. 3. Measuring instrumentations: Rohde & Schwarz ESVP Test Receiver ( 20 - 1300 MHz ) with a CISPR weighting QP detector, 6 dB bandwidth set at 120 KHz. In the frequency range above 1000 MHz Spectrum Analyzer FMSM26 and Analyzer Display Unit FSA- D are used, bandwidth set at 100 kHz. 4. Measuring antenna: Broad-band antenna for the frequency range 30 - 300 MHz and frequency range 300 - 1000 MHz, connected with 10 meters coaxial cable. Cable loss of the coaxial cable included in the Antenna Factor for measurement data. The antennas are capable of measuring both horizontal and vertical polarizations. In the frequnecy range above 1 GHz horn-antenna RGA 50/60 is used. 5. Frequency range scanned: The frequency range 30 - 5000 MHz has been scanned.
