SAFETY TRANING INFORMATION
This Radio has been tested and complies with the Federal Communications Commission (FCC) RF
exposure limits for Occupational Use/Controlled exposure environment. In addition, it complies with the
following Standards and Guidelines:
exposure limits for Occupational Use/Controlled exposure environment. In addition, it complies with the
following Standards and Guidelines:
- FCC 96-326, Guidelines for Evaluating the Environmental Effects of Radio-Frequency Radiation.
- FCC OET Bulletin 65 Edition 97-01 (1997) Supplement C, Evaluating Compliance with FCC Guidelines for
- FCC OET Bulletin 65 Edition 97-01 (1997) Supplement C, Evaluating Compliance with FCC Guidelines for
Human Exposure to Radio Frequency Electromagnetic Fields.
- ANSI/IEEE C95.1-1992, IEEE Standard for Safety Levels with Respect to Human Exposure to Radio
Frequency Electromagnetic Fields, 3kHz to 300 GHz.

Electromagnetic Fields-RF and Microwave.
WARNING:
This 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.

CAUTION:
To ensure that your expose to RF electromagnetic energy is within the FCC allowable limits for occupational
use, always adhere to the following guidelines:
use, always adhere to the following guidelines:
- This radio is NOT approved for use by the general population in an uncontrolled environment. This
radio is restricted to occupational use, work related operations only where the radio operator
must have the knowledge to control its RF exposure conditions.
must have the knowledge to control its RF exposure conditions.
- When transmitting, hold the radio in a vertical position with its microphone 1 to 2 inches (2.5 to 5
cm) away from your mouth and keep the antenna at least 1 inch (2.5cm) away from your head and
body.
body.
- The radio must be used with a maximum operating duty cycle not exceeding 50 %, in typical
Push-to-Talk (PTT) configurations.
DO NOT transmit 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 red LED on the top of the radio is illuminated. You can cause
the radio to transmit by pressing the PTT button.

Electromagnetic Interference/Compatibility
During transmissions, this 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,
health care facilities, aircraft, and blasting sites.
