Important Information
RF Energy Exposure Information
RF Energy Exposure Awareness And Control
Information For Fcc Occupational Use Requirements
Ibefore 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.
This radio is intended for use in occupational/controlled conditions, where
users have full knowledge of their exposure and can exercise control over
their exposure to remain below RF exposure limits. This radio is NOT
authorized for general population, consumer, or any other use.
Changes or modifications not expressly approved by Shenzhen Excera
Technology 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
Important Information
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:
http://www.fcc.gov/oet/rfsafety/rf-faqs.html
http://www.osha.gov./SLTC/radiofrequencyradiation/index.html
Important Information
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.
Operation Safety Recommendations
Occupational Safety Guidelines And Safety Training Information
To ensure bodily exposure to RF electromagnetic energy is within the FCC allowable limits
for occupational use. Always adhere to the following basic guidelines:
The push-to-talk button should only be depressed when intending to send a voice
message.
The radio should only be used for necessary work-related communications.
The radio should only be used by authorized and trained personnel. It should never be
operated by children.
Do not attempt any unauthorized modification to the radio. Changes or modifications
to the radio may cause harmful interference and/or cause it to exceed FCC RF
exposure limits. Only qualified personnel should service the radio.
Always use only authorized accessories (antennas, control heads, speakers/mics,
etc.). Use of unauthorized accessories can cause the FCC RF exposure compliance
requirements to be exceeded.
The information listed above provides the user with information needed to make him or her
aware of a RF exposure, and what to do to assure that this radio operates within the FCC
exposure limits of this radio.
