SAFETYTRAINING INFORMATION
Your HYT radio generates RF electromagnetic energy during transmit mode.
This radio is designed for and classified as “Occupational Use Only”, meaning
it must be used only during the course of employment by individuals aware of
the hazards, and the ways to minimize such hazards. This radio is NOT
intended for use by the “General Population” in an uncontrolled environment.
This radio has been tested and complies with the FCC RF exposure limits for
“Occupational Use Only”. In addition, your HYT radio complies with the following
Standards and Guidelines with regard to RF energy and electromagnetic energy levels
and evaluation of such levels for exposure to humans:
„ FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with FCC
Guidelines for Human Exposure to Radio Frequency Electromagnetic Fields.
„ American National Standards Institute (C95.1-1992), IEEE Standard for Safety Levels
with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz
to 300 GHz.
„ American National Standards Institute (C95.3-1992), IEEE Recommended Practice
for the Measurement of Potentially Hazardous Electromagnetic Fields– RF and
Microwave.
„ The following accessories are authorized for use with this product. Use of accessories
other than those (listed in the instruction) specified may result in RF exposure levels
exceeding the FCC requirements for wireless RF exposure.
To ensure that your expose to RF electromagnetic energy is
within the FCC allowable limits for occupational use, always
adhere to the following guidelines:
„ DO NOT operate the radio without a proper antenna attached, as this may damaged
the radio and may also cause you to exceed FCC RF exposure limits. A proper
antenna is the antenna supplied with this radio by the manufacturer or antenna
specifically authorized by the manufacturer for use with this radio.
„ DO NOT transmits for more than 50% of total radio use time (“50%duty cycle”).
Transmitting more than 50% of the time can cause FCC RF exposure compliance
requirements to be exceeded. The radio is transmitting when the “TX indicator” lights
red. You can cause the radio to transmit by pressing the “PTT” switch.
„ ALWAYS keep the antenna at least 2.5 cm (1 inch) away from the body when
transmitting and only use the HYT belt-clip which is listed in instructions when
attaching the radio to your belt, etc., to ensure FCC RF exposure compliance
requirements are not exceeded. To provide the recipients of your transmission the
best sound quality, hold the antenna at least 5 cm (2 inches) from your mouth, and
slightly off to one side.
The information listed above provides the user with the information needed to make
him or her aware of RF exposure, and what to do to as-sure that this radio operates with
the FCC RF exposure limits of this radio.
Electromagnetic Interference/Compatibility
During transmissions, your HYT radio generates RF energy that can possibly cause
interference with other devices or systems. To avoid such interference, turn off the radio in
areas where signs are posted to do so. DO NOT operate the transmitter in areas that are
sensitive to electromagnetic radiation such as hospitals, aircraft, and blasting sites.
Occupational/Controlled Use
The radio transmitter is used in situations in which persons are exposed as consequence
of their employment provided those persons are fully aware of the potential for exposure
and can exercise control over their exposure.
