DESCRIPTION
The MCT242 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 MCT242 is not designed for multiple antenna applications and
should not be used to transmit simultaneously with any other
transmitter.
OPERATION
The MCT242 is 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 MCT242 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 MCT242 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.

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.

FCC and IC SAR Statement
This device meets the government's requirements for exposure to
radio waves. The guidelines are based on standards that were
developed by independent scientific organizations through periodic and
thorough evaluation of scientific studies. The standards include a
substantial safety margin designed to assure the safety of all persons
regardless of age or health.
The SAR limit of USA (FCC/IC) is 1.6 W/kg averaged over one gram of
tissue. Device types: MCT242 has also been tested against this SAR
limit. This device has been tested and meets the RF exposure
guidelines with a conservative distance 0 mm. The use of belt clips,
holsters and similar accessories should not contain metallic
components in its assembly. The use of accessories that do not satisfy
these requirements may not comply with RF exposure requirements,
and should be avoided.
