The M222P operates on GMRS (Gerneral 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 M222P. 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 M222P. GMRS users should also
cooperate by engaging in permissible transmissions only, avoiding channel
interference with other GMRS users, and being prudent with the lenght of their
transmission time.
Questions regarding the license application should be directed to the FCC at
1-888-CALL FCC. Additional information is available on the FCC's website 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 Statse Federal Communications Commission, Code of Federal
Regulations: 47 CFR part 2 sub-part J
= American National Standards Indtitute (ANSI) / Institute of Electrical
and Electronic Engineers (IEEE) C95. 1-1992
= Institute of Electrical and Electronic Engineers (IEEE) C95.1-1999
Edition
= National Council on Radiation Protection and Measurements (NCRP)
of the Unitates, Report 86, 1986
= International Commission on Non-Ionizing 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 measuable RF energy exposure only when
transmitting.

IMPORTANT NOTICE FCC LICENCE REQUIRED
FCC Warning: For transmitter designed to operate above 25 MHz shall not be
certificated for use under this part if the operator can program and transmit on
frequencies, other than those programmed by the manufacturer, service or maintenance
personnel, using the equipment’s external operation controls.
The operator’s manual for this equipment states on page 7 under ‘installation and
programming’ that the equipment supplier or qualified radio tradesman using the Titan
Base Repeater programming software are the only ones that can change the transmitting
frequencies.
