DESCRIPTION
The MCT243 is a direct sequence spread spectrum transceiver unit,
designed to be compatible with US (FCC Part 15.247), Canadian (RSS-
247), EU(EN 60950-1, EN 300 328, EN 301 489) and
Australian(AS/NZS 4268) regulations for license free use in the 2.4
GHz ISM band. The MCT2412 is designed for mobile applications in
accordance to Part 2.1091(b).
The MCT243 is not designed for multiple antenna applications and
should not be used to transmit simultaneously with any other
transmitter.
OPERATION
The MCT243 equipped a radio transceiver module for the 2.4 GHz ISM
bands. The transceiver microcontroller includes a CPU, GPI/O, a fully
integrated frequency synthesizer, a power amplifier, a modulator and a
receiver unit. The MCT243 microcontroller monitors the input data.
The data is sent to the RF processor and then to RF circuit, and then to
the antenna. The data received from antenna is sent to the
microcontroller for processing. The microcontroller is responsible for
the control of the entire communication. The MCT243 transceiver
contains a DC regulator which generates a constant 1.8 VDC for the
digital circuitry. The RF section runs on the 3.3V supply.

The MCT243 is Direct Sequence Spread Spectrum that can use one of
16 channels, where Channel 1 is 2.405GHZ and Channel 16 is
2.480GHZ.
Where Used
Typical applications for the MCT243 are to controlling valves, relays and
lights on agricultural equipment, construction equipment, and other
similar equipment.

FCC Statement
FCC Statement
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.
Note: This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in particular installation. If this
equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by one or more
of the following measures:
--Reorient or relocate the receiving antenna.
--Increase the separation between the equipment and receiver.
--Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
--Consult the dealer or an experienced radio/TV technician for help.
Changes or modifications not expressly approved by the party
responsible for compliance could void your authority to operate the
equipment.
Radiation Exposure Statement
This equipment complies with FCC radiation exposure limits set forth for
an uncontrolled environment. User should avoid un-intended operation of
usage when it is collocated with other transmitters or antenna. The
distance between user and products should be no less than 20cm.
