SAFETYTRAINING INFORMATION
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.
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.
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.
To ensure that your expose to RF electromagnetic
energy
is
within
occupational use, always adhere to the following
guidelines:
