Important Information
RF Energy Exposure Information
RF Energy Exposure Awareness And Control
Information For Fcc Occupational Use Requirements
Ibefore using the Digital 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.
WARNING
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 HQT Science&Technology Co., Ltd.could void the user's
authority to operate the equipment.
CAUTION
This Digital poartable 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 digital portable 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 digital portable 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.
