Page 2 of 6 12/2003, CATTRON-THEIMEG™ 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.
12/2003, CATTRON-THEIMEG™ Page 3 of 6 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.

Transceiver & RF Amplifier Board LED Indicators LED Description Transceiver Power 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
