FCCID_691557

Application No.: HM157114

Date: 2006-07-26

FCC ID: QEASUVPLANE49

Circuit Description

The 49.86MHz crystal oscillator drives the base of U1 the final/buffer amplifier. The
modulation provided by U1. The output of U1 has the matching network consisting of C6,
C7, C8 and L3, 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 29.5 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 9.0 Volt (“6F22” size battery x 1) primary battery.

Operation Descriptions

The transmitter is a remote control toy operating at 49.861MHz band. The transmitter is
powered by a 9Vd.c. battery (6F22) 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 Pulse transmitter, Modulation by IC; and type is Pulse modulation.
