FCC ID Location FCC ID Label Sample FCC ID: REKFF27A This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.

Operation: Size AA x 2_DC3V Drawing Ref.: 1 : 64 R/C MINI RACER_TX U1 (TX2) is a 5 functional remote encoder IC, with transistor Q1, Q2 and other components combined as RF transmitter circuit. The IC Pin 14, 1, 4 and 5 control left, right, backward, forward and encoding signal output respectively. Data output from Pin 8 and modulate with 27.145MHz oscillator that achieved by Q2, Y1, R3, C2, and L1. RF power amplifier Q1, L2, C3, C4, R8 is use to enlarge the transmission range, the output frequency through LC filter C5, C8, C9, L3 and L4, to eliminate the harmonic frequency then transmitted the radio signal by aerial E1.
