WARNING 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.
MODIFICATION WARNING STATEMENT
Changes or modifications not expressly approved by the party responsible for compliance could void
the user's authority to operate the equipment.
DIGITAL DEVICE STATEMENT
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 transceiver.
--Connect the equipment into an outlet on a circuit different from that
to which the transceiver is connected.
--Consult the dealer or an experienced radio/TV technician for help.

Throughout this manual the term transmitter unit, TX, TA-7650C refers to the transmitter unit.
The term transceiver, TR, TR-7750C refers to any variant of the transceiver unless specifically noted
in the text and the term receiver, RX and RA-7203C is used for the receiver unit.
1.2 Layout of the transceiver
The receiver unit, RA-7203C operates as an independent receiver. The transmitter unit TA-7650C
operates as an independent transmitter, but requires the power supply unit, PSU-7002 for operation
on AC power. The receiver and transmitter units may be placed in entirely different locations or
together when configured as a transceiver.
