KCD24T01 RF Module production instruction manual

1. Summary: KCD24T01 RF Module is a RF transceiver module
that can work in the 2.4GHZ band for toy remote control car

2. Electrical parameters:
Operating voltage：DC 4.5V(BATTERY POWERED)
Operating current：21ma

Operating frequency: 2402MHZ-2480MHZ
The RF output maximum power: -14dbm
Modulation mode: GFSK

The modulation frequency deviation maximum: 280KHZ

3.Functional description:
Modules are installed on a PCB board,to connect power
switch by turning on the switch on the base board. At the
mean time, there are 4 keys and 1 LED light on the board is
also connected to corresponding pin on module. LED light
will slowly flash at first after switching on the power and
module begins to match codes. Then turn on the other
receiving module power, LED light will flash quickly off for 2
seconds after 1-3 seconds later which means the connection
between the two modules has been established, codes have
been matched. Then proceed into the normal mode, the
corresponding orders can be sent out as RF signals via

transmitting antenna by pressing buttons of forward,
backward, turn left and turn right. modula powered by AA

battery.Note: this EUT is powered by the battery only(1.5V*3AA)

FCC Caution: 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.

This device and its antenna(s) must not be co-located or operating in conjunction with any
other antenna or transmitter.

FCC RF Exposure Statement

The modular is comply with any applicable RF exposure requirements.

An intentional radiator shall be designed to ensure that no antenna other than that
furnished by the responsible party shall be used with the device. The use of a permanently
attached antenna or of an antenna that uses a unique coupling to the intentional radiator
shall be considered sufficient to comply with the provisions of this Section. The
manufacturer may design the unit so that a broken antenna can be replaced by the user,
but the use of a standard antenna jack or electrical connector is prohibited. This
requirement does not apply to carrier current devices or to devices operated under the
provisions of Sections 15.211, 15.213, 15.217, 15.219, or 15.221. Further, this
requirement does not apply to intentional radiators that must be professionally installed,
such as perimeter protection systems and some field disturbance sensors, or to other
intentional radiators which, in accordance with Section 15.31(d), must be measured at the
installation site. However, the installer shall be responsible for ensuring that the
proper antenna is employed so that the limits in this Part are not exceeded.
This device complies with part 15.203.
