WARNINGS
WARNING:
CHANGES OR MODIFICATIONS NOT EXPRESSLY APPROVED BY
CATTRON-THEIMEG™ COULD VOID THE USER’S AUTHORITY TO
OPERATE THE EQUIPMENT.
FAILURE TO COMPLY WITH THIS
WARNING MAY RESULT IN SERIOUS INJURY OR DEATH TO
PERSONNEL AND DAMAGE TO EQUIPMENT.
WARNING:
TO SATISFY FCC RF EXPOSURE REQUIREMENTS FOR PORTABLE
TRANSMITTING DEVICES, A SEPARATION DISTANCE OF 2.5 CM
(APPROX. 1 INCH) OR MORE SHOULD BE MAINTAINED BETWEEN THE
ANTENNA OF THE OCU AND PERSONS DURING DEVICE OPERATION.
TO INSURE COMPLIANCE, OPERATION AT CLOSER THAN THIS
DISTANCE IS NOT RECOMMENDED. THE ANTENNA USED FOR THIS
TRANSMITTER MUST NOT BE CO-LOCATED IN CONJUNCTION WITH
ANY OTHER ANTENNA OR TRANSMITTER.
FAILURE TO COMPLY
WITH THIS WARNING MAY RESULT IN SERIOUS INJURY OR DEATH TO
PERSONNEL AND DAMAGE TO EQUIPMENT.
WARNING:
TO SATISFY FCC RF EXPOSURE REQUIREMENTS FOR MOBILE
TRANSMITTING DEVICES, A SEPARATION DISTANCE OF 20 CM
(APPROX. 8 INCHES) OR MORE SHOULD BE MAINTAINED BETWEEN
THE ANTENNA OF THE LCU AND PERSONS DURING DEVICE
OPERATION.
TO INSURE COMPLIANCE, OPERATION AT CLOSER
THAN THIS DISTANCE IS NOT RECOMMENDED. THE ANTENNA USED
FOR THIS TRANSMITTER MUST NOT BE CO-LOCATED IN
CONJUNCTION WITH ANY OTHER ANTENNA OR TRANSMITTER.
FAILURE TO COMPLY WITH THIS WARNING MAY RESULT IN SERIOUS
INJURY OR DEATH TO PERSONNEL AND DAMAGE TO EQUIPMENT.
IMPORTANT NOTICE FOR CLASS ‘A’ UNINTENTIONAL RADIATORS:
This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at his own expense.

Radio Frequency (RF) Transceiver.
Depending upon the System Operating Frequency, the RCR 'Gold Box' may incorporate a 220 MHz or
a R3HNX (450 MHz band) Transceiver Board.
The Transceiver Board is a multi channel, synthesized RF receiver with a Liquid Crystal Display
(LCD). Additionally, it has a built in RF transmitter for ‘POLLING™ ’ data transmission. The receiver
section incorporates a microprocessor and uses Digital Signal Processing (DSP) techniques to
selectively recover digital messages using CATTRON-THEIMEG™ protocol. The receiver section also
has LED indicators for:
• Power ON
• Carrier Detect (RF signal or carrier is present)
• VCO Lock (receiver locked on freq.)
• Data (received message data)
• Q-sync (synchronization pulse)
The RF Power Amplifier Board is a high power RF amplifier that connects between the R3HNX
Transceiver Board and the Antenna Connector. An on-board LED indicator shows when transmitted
digital RF ‘POLLING™ ’ data from the transmitter section is being amplified and sent to the RCT. Note
that systems operating in the 220 MHz Band do not require this board.
Opening the front door of the RCR enclosure and removing the 'Gold Box' lid will expose the
Transceiver Board, and in the case of a R3HNX MHz transceiver board, the ‘companion’ RF Power
Amplifier Board. Referring to Figure 1-1 and Table 1-1 below, transceiver and amplifier board LED
indicators indicate system status and are particularly useful to the technician when troubleshooting and
adjusting the transceiver.

Description
This red LED indicates the presence of DC power on the transceiver
circuit board.
Carrier Detect
The green Carrier Detect LED indicates that the receiver section is
receiving a RF signal.
Data
This yellow LED indicates that the received RF message contains data.
Q-Sync
This orange LED indicates an interrupt that signifies the computer/
decoder has received a new message.
VCO Lock
This red LED (located underneath the EMI/RFI shield on the R3HNX
board) illuminates when the transceiver frequency synthesizer is unable to
lock onto the required frequency.
RF Power LED
This red LED (located on the RF amplifier) flashes when the transmitted
digital RF ‘POLLING™ ’ data from the transmitter is being amplified and
sent to the RCT
