It operates over an ultra-wide frequency range of 500 to 937.5 MHz with four BNC RF inputs, one BNC RF output and four RF input blue status indicator LEDs. A 50 ohm load connector is attached to each RF input for use with no antenna input to prevent unwanted radio interference noise. ACR 4 greatly improves the transmission quality, reduces intermodulation distortion and signal loss due to multipath interference. The ACR 4 is compatible with the Linkx wireless fixed transmitter TG-100ST/200ST/ 300ST/288ST/500ST. The ACR 4 features a black, rugged, half-rack metal enclosure. The optional rack mount bracket kit allows you to mount one or two ACR 4 combiners into the 1 RU space of any standard 19-inch equipment rack. If there is no signal coming at the input, be sure to connect the included 50 ohm load connector to the BNC socket to prevent unwanted radio interference noise.

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 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. FCC Caution: To assure continued compliance, any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. (Example - use only shielded interface cables when connecting to computer or peripheral devices). FCC Radiation Exposure Statement This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.

The complexity of the technical specifications, however, means that full and thorough testing is impractical for both technical and economic reasons. Furthermore, there is no guarantee that a test sample which has passed all the relevant tests conforms to a specification. Neither is there any guarantee that such a test sample will interwork with other genuinely open systems. The existence of the tests nevertheless provides the confidence that the test sample possesses the qualities as maintained and that is performance generally conforms to representative cases of communications equipment.
