Mattel #B2878 6.0V TRUCK 49. 860 MHz Receiver Operational Description The TRUCK (6.0V NiCD) powered, radio controlled toy vehicle. It is designed to operate on a single fixed frequency in the 49.82 – 49.90 MHz band. See the attached block diagram and schematic. The vehicle receiver receives and demodulates the AM transmitted signal from the transmitter, using a standard super-regenerative AM receiver/demodulator circuit comprised of ANT1, Q1, L1, L3, L4 and associated passive components. L4 is a tunable core slug inductor that is used to tune the receiver for maximum sensitivity. The output of the AM receiver/demodulator is AC coupled to a high input impedance CMOS inverter stage of the U1 decoder IC biased into their linear region through C12, C14, C9, R4, R13, R6, R7 which amplify, filter and shape the data. After the last inverter stage the incoming waveform is a digitized enough to be fed into the SI pin for on-chip decoding. A Zener regulator circuit comprised of C11, C18, R3, D1, C8, C15, creates the supply voltage, VDD for the super-regenerative radio, decoder IC and Comparator section. Drive motors M are controlled by the U1 decoder IC, low power switching transistors Q6, Q7, and a high power H-bridge comprised of Q4, Q5, Q8, Q9, The Steering Motor M1 are controlled by the U1 decoder IC low power switching transistors Q12,Q14,and a high power H-bridge comprised of Q10,Q11,Q13,Q15, All tuning and verifications are performed by the manufacturer and there are no adjustments which can be made by the user. No external ground is required or used with this receiver.

Measurements in both horizontal and vertical polarities were performed. During the test, each emission was maximized by: having the EUT continuously working, investigated all operating modes, rotated about all 3 axis (X, Y & Z) and considered typical configuration to obtain worst position, manipulating interconnecting cables, rotating turntable, varying antenna height from 1m to 4m in both horizontal and vertical polarizations. The emissions worst-case are shown in Test Results of the following pages. Note: According to ANSI C63.4: 2000 Section 12. During the test, signal generator would be transmit unmodulated CW signal and adjust the signal level to a EUT in order to measure the worst case emission. *:OATS [Open Area Test Site] located at HKSTC with a metal ground plane filed with the FCC pursuant to section 2.948 of the FCC rules, with Registration Number: 90657.
