2. INTRODUCTION
2.1 GENERAL
The RITRON RLR-460 Repeater is a synthesized table-top UHF repeater that operates in the 450 to 470
MHz FM communications band. Its maximum output power level is either 2 watts or 5 watts, depending
upon the type of power supply which is available to power the unit. The unit receives signals originating at
handheld, mobile, or fixed stations on one frequency and simultaneously retransmits the signals on a
second frequency. This type of operation is described as full duplex. The unit contains an integral
duplexer which allows a single antenna to be used for simultaneous transmission and reception. Full
duplex operation with a repeater enables mobile and handheld units to communicate over much greater
distance than is possible without a repeater. The Repeater is designed to be powered from an external DC
power source.
2.2 INSPECTION
Inspect the unit immediately after delivery and report any damages to the shipping company.
2.3 MODEL IDENTIFICATION
The Repeater’s model, serial number, and FCC identification number appear on a label attached to the rear
panel.
2.4 FCC REGULATIONS
The Federal Communications Commission (FCC) requires that the radio owner obtain a station license
before using the equipment to transmit. The user is not required to obtain an operating license. The station
licensee is responsible for proper operation and maintenance of his radio equipment and for ensuring that
transmitter power, frequency, and occupied bandwidth are within the limits specified by the station license.
This is effected by aligning the unit per the instructions in the Alignment section of this manual as well as
periodically checking that transmitter and deviation. Because the RLR-460 contains a transmitter, THE
REPEATER MUST BE LICENSED BEFORE USE. A RITRON dealer can help with obtaining an FCC
license.
2.5 RF SAFETY ISSUES
On August 25, 1997, the FCC adopted the second of two Orders finalizing its rules regarding compliance
with safety limits for human exposure to radio frequency (RF) emissions. All transmitting facilities,
operations and devices regulated by the FCC, including this product, must be in compliance with the RF
exposure limits contained in Code of Federal Regulations (CFR) 47 parts 1.1307(b)(1)-(b)(3). It is the
responsibility of the licensee or grantee to either take action to bring the facility, operation or device into
compliance or file an Environmental Assessment with the FCC. The following precautions should be taken
with regard to the use of this equipment:
This product has been evaluated for compliance with the maximum permissible exposure limits for RF
energy at the maximum power rating of the unit and with the two antennas sold for use with this product by
RITRON. To ensure compliance with the General Population/Uncontrolled maximum exposure limits,
please observe the following:
When the AFB-1545 articulated joint dual-band antenna is mounted to the rear of the unit, mount the RLR-
460 in such a way, and in a location, that will ensure that all persons will be at least 17 inches (44 cm) away
from the antenna.
When the RAM-1545 remote magnetic mount antenna is used, mount the antenna in a location that will
ensure that all persons will be at least 9 inches (23 cm) away from the antenna.
