both workers and the general public. These recommended RF exposure levels include substantial margins
of protection. All two-way radios marketed in North America are designed, manufactured, and tested to
ensure they meet government-established RF exposure levels. In addition, manufacturers also recommend
specific operating instructions to users of two-way radios. These instructions are important because they
inform users about RF energy exposure and provide simple procedures on how to control it. Refer to the
following websites for more information on what RF energy exposure is and how to control exposure to
assure compliance with established RF exposure limits:
1.2.1
Federal Communications Commission Regulations
Before marketing in the United States, the M5300 and M7300 two-way mobile radios were tested to
ensure compliance with FCC RF energy exposure limits for two-way mobile radios. When two-way
radios are used as a consequence of employment, the FCC requires users to be fully aware of and able to
control their exposure to meet occupational requirements. Exposure awareness can be facilitated by the
use of a label directing users to specific user awareness information. Each radio has an RF exposure
product label. Also, this Installation and Product Safety Manual and the applicable Operator’s Manual
include information and operating instructions required to control RF exposure and to satisfy compliance
requirements.
1.3 COMPLIANCE WITH RF EXPOSURE STANDARDS
The M5300 and M7300 two-way mobile radios are designed and tested to comply with a number of
national and international standards and guidelines regarding human exposure to RF electromagnetic
energy. The radios comply with the IEEE and ICNIRP exposure limits for occupational/controlled RF
exposure environment at duty-cycle times of up to 50% (50% transmit, 50% receive), and they are
authorized by the FCC for occupational use. In terms of measuring RF energy for compliance with the
FCC exposure guidelines, each radio’s antenna radiates measurable RF energy only while it is
transmitting (talking), not while it is receiving (listening), or in a standby mode.
The M5300 and M7300 two-way mobile radios comply with the following RF energy exposure standards
and guidelines:
United States Federal Communications Commission (FCC), Code of Federal Regulations; 47 CFR
§ 2 sub-part J.
American National Standards Institute (ANSI)/Institute of Electrical and Electronic Engineers (IEEE)
C95.1-2005.

(All Frequency Bands).”
CAUTION
Table 1-1 lists the recommended minimum safe lateral distances for a controlled
environment and for unaware bystanders in an uncontrolled environment, from
transmitting antennas (i.e., monopoles over a ground plane, or dipoles) at rated radio
power for a mobile radio installed in a vehicle. Transmit only when unaware
bystanders are at the uncontrolled recommended minimum safe lateral distance away
from the transmitting antenna.
