RF Energy Exposure Awareness And Control
Information For Fcc Occupational Use Requirements
I before using the two-way portable radio, review the following important RF energy awareness and control
information and operational instructions. Comply with this information and instructions in order to ensure
compliance with RF exposure guidelines.e the capability to access information in that form.
Changes or modifications not expressly approved by Kirisun Communications Co., Ltd. could void the
user's authority to operate the equipment.
This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide
communications between two or more users over a distance. It uses RF energy or radio waves to send and
receive calls. RF energy is one form of electromagnetic energy. Other forms include, but are not limited to,
electric power, sunlight, and x-rays. RF energy, however, should not be confused with these other forms of
electromagnetic energy, which, when used improperly, can cause biological damage. Very high levels of x-rays,
for example, can damage tissues and genetic material.Experts in science, engineering, medicine, health, and
industry work with organizations to develop standards for exposure to RF energy.These standards provide
recommended levels of RF exposure for 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.

Federal Communications Commission Regulations
Before it was marketed in the United States, the Digital portable radio was tested to ensure compliance with FCC
RF energy exposure limits for two-way portable 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. The radio has an RF exposure product label.Also, the Product Safety Manual and this
Operator’s Manual include information and operating instructions required to control RF exposure and to satisfy
compliance requirements.
