FCC ID: G6D10833HK
Circuit Description

The 49.86MHz crystal oscillator drives the base of Q1 the final/buffer amplifier.
The modulation provided by IC. The output of Q2 has the matching network consisting of
C9, C10, C11, L3 and L4 that limit the harmonic content and effect the proper coupling of
the antenna to the output stage.

Antenna, Ground and Power Source

The antenna consists of a 33.5cm long Metal antenna.
There is no external ground connection. The ground is only that of the printed circuit board.
Electric current is supplied by a 3 Volt (“AA” size battery x 2) primary battery

Operation Descriptions

The transmitter is a remote control toy operating at 49.86MHz band. The transmitter is
powered by a 3V battery (“AA” size battery x 2) and the transmitting frequency is crystal
controlled. There are 2 joysticks to control the forward reverse motor and director of
movement. The operation is achieved by different combinations of form pulse modulating
signal on the 49.86MHz carrier frequency.

Remarks:
The transmitter is a 2 joystick transmitter. The EUT continues to transmit while joystick is
being pressed. It is joystick transmitter, Modulation by IC; and type is Pulse modulation.
