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 com-

prise the GMRS channels of the GXT-400. Serious penalties could result for unli-

censed 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 1-

886-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.
