(Tested with Headset Model: AVP-1) Model GXT720/775 Series ® Page 4www.midlandradio.com IMPORTANT NOTICE, FCC LICENSE REQUIRED FOR GMRS OPERATION The GXT720/775 Series operates on GMRS (General Mobile Radio Service) frequencies which require an FCC (Federal Communications Commission) license. You must be licensed prior to operating on channels 1 - 7 or 15 - 22, which comprise the GMRS channels of the GXT720/775 Series. Serious penal- ties could result for unlicensed use of GMRS channels, in violation of FCC rules, as stipulated in the Communications Act's Sections 501 and 502 (amended). You will be issued a call sign by the FCC which should be used for station identification when operating the radio on GMRS channels. You should also cooperate by engaging in permissible transmissions only, avoiding channel interference with other GMRS users, and being prudent with the length of their transmission time. To obtain a license or ask questions about the license application, contact the FCC at 1-888-CALL FCC or go to the FCC's website: http://www .fcc.govand request form 605. Exposure To Radio Frequency Energy Your Midland radio is designed to comply with the following national and international standards and guidelines regarding exposure of human being to radio frequency electromagnetic energy: - United States Federal Communications Commission, Code of Federal Regulations: 47 CFR part 2 sub-part J - American National Standards Institute (ANSI)/Institute of Electrical & Electronic Engineers (IEEE) C95. 1-1992 - Institute of Electrical and Electronic Engineer (IEEE) C95. 1-1999 Edition - National Council on Radiation Protection and Measurements (NCRP) of the United States, Report 86, 1986 - International Commission on Non-lonizing Radiation Protection (ICNIRP) 1998 To control your exposure and ensure compliance with the general population or uncontrolled environment exposure limits, transmit no more than 50% of the time. The radio generates measurable RF energy exposure only when transmitting. Model GXT720/775 Series IMPORTANT:Changes or modifications to this unit not expressly approved by MIDLAND RADIO CORP. could void your right to operate this unit. Your radio is set up to transmit a regulated signal on an assigned frequency. It is against the law to alter or adjust the settings inside the COMMUNICATOR to exceed those limitations. Any adjustment to your radio must be made by qualified technicians. ® Page 5www.midlandradio.com CONTROLS LCD DISPLA Y 1. KEY LOCK ICON – Indicates KEY LOCK mode is on. 2.
