These assemblies are located on the combiner, splitter and power amplifier boards. The fumes and dust of beryllium oxide is also toxic and should only be treated by trained personnel using proper precautions. Federal law and most state laws strictly prohibit disposal of beryllium oxide as a public waste. FCC Requirements FCC regulations state that: 1. Radio transmitters may be tuned or adjusted only by persons holding a general class commercial radiotelephone operator’s license, a registered engineer or by personnel working under their immediate supervision. 2. The RF power output of a radio transmitter shall be no more than that required for satisfactory technical operation considering the area to be covered and local conditions. 3. The frequency, deviation, and power of a base station transmitter must be maintained within specified limits. It is recommended, therefor, that these three parameters be checked before the station is placed in service. 4. The power input to the final radio frequency stage shall not exceed the maximum figure specified on the current station authorization. This power input shall be measured and the results recorded: a. When the transmitter is initially installed. b. When any change is made in the transmitter, which may increase the power input. c. At intervals not to exceed on year. FCC Interference Warning FCC regulations state that: This equipment generates, uses, and can radiate radio frequency energy and if not installed and used in accordance with the instructions manual, may cause interference to radio communications. As temporarily permitted by regulation it has not been tested for compliance with the limits for Class A computing devices pursuant to Sub-part J of Part 15 of FCC Rules, which are designed to provide reasonable protection against such interference. Operation of this equipment in a residential area is likely to cause interference in which case the user at his own Version 3 iii 07/18/01 Preface expense will be required to take whatever measures may be required to correct the interference. OSHA Safety Standards The United States Department of Labor, through the provisions of the Occupational Safety and Health Act, has established an electromagnetic energy safety standard with applies to the use of this equipment. Proper use of this radio equipment wil…
