IMPORTANT NOTICE, FCC LICENCE REQUIRED
The GXT-400 operate on GMRS (General Mobile Radio Service) frequencies
which require an FCC (Federal Communications Commission) license.
Information on how to apply for a license is included in the owner's manual. A
user must be licensed prior to operating on channels 1 - 7 or 15 - 22, which comprise the GMRS channels of the GXT-400. Serious penalties 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).
Licensed users will be issued a call sign by the FCC which should be used for
station identification when operating the GXT-400. GMRS users 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.
Questions regarding the license application should be directed to the FCC at 1886-CALL FCC. Additional information is available on the FCC's web-site at
www
.fcc.gov/wtb/prs/genmbl.html
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.
