DESCRIPTION
The MCT245 is a frequency
hopping spread spectrum
transceiver unit, designed to be
compatible with US (FCC Part
15.247), Canadian (RSS-210),
EU(EN 60950-1, EN 300 328, EN
301 489) and Australian()
regulations for license free use
in the 2.4 GHz ISM band. The
MCT245 is designed for mobile
applications in accordance to
Part 2.1091(b).
The MCT245 remote control
products are assembled by Kar-
Tech, at Kar-Tech. There are no
user serviceable parts on the
MCT245 transceiver.
The MCT245 is not designed for
multiple antenna applications
and should not be used to
transmit simultaneously with
any other transmitter.
OPERATION
The MCT245 is a radio
Receiver product for the 2.4
GHz ISM bands. The
Receiver microcontroller
includes a CPU, GPI/O, a
fully integrated frequency
synthesizer, a power amplifier,
a modulator and a receiver
unit. The data received from
antenna is sent to the
microcontroller for
processing. The MCT245
microcontroller monitors the
input data, received data
and controls outputs. The
system data is sent to the
RF processor and then to RF
circuit, and then to the
antenna. The microcontroller is
responsible for the control of
the entire communication.
The MCT245 transceiver
contains a DC regulator which
generates a constant 1.8 VDC
for the digital

MCT245 RECEIVER
3
circuitry. The RF section runs on
the 3.3V supply.
The MCT245 uses Frequency
Hopping Spread Spectrum
that uses 16 channels for
any hop mode, between
2.407GHZ and 2.470GHZ, with
1MHZ resolution.
The receivers are matched
to the transmitters to use the
same channels and sequence
as the transmitter’s signals.
The MCT245 controls
outputs which can operate
relays, hydraulic valves, lights,
or other similar load devices,
according to customer
requirements.
Where Used
Typical applications for
the MCT245 are to
controlling valves, relays and
lights on agricultural
equipment,
construction equipment, and
other similar equipment.

D) Do not operate the MCT245
without an antenna.
E) Documentations: In the
host’s User Manual
include the following:
a. That there are no user
serviceable parts in
the radio product.
They should not
remove or install radio
modules.
b. The “Instructions To
The User” section.
c. The “Industry Canada
Statement”.
d. Include in the manual,
“This device is granted
for use in Mobile only
configurations in
which the antennas
used for this
transmitter must be
installed to provide a
separation distance of
at least 20cm from all
person and not be co-
located with any other
transmitters except in
accordance with FCC
and Industry Canada
multi-transmitter
product procedures.”

INSTRUCTION TO THE USER
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.
Changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate the
equipment.
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 a 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.
