WARNING! FCC RF EXPOSURE REQUIREMENTS
FCC RF Exposure Compliance Requirements for Occupational Use Only:
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:
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 Human Exposure to Radio Frequency Electromagnetic Fields.
ANSI/IEEE C95.1-1992, IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Fre-
quency Electromagnetic Fields, 3 kHz to 300 GHz.
ANSI/IEEE C95.3-1992, IEEE Recommended Practice for the Measurement of Potentially Hazardous Elec-
tromagnetic Fields - RF and Microwave.
This radio is NOT approved for use by the general population in an uncontrolled exposure environ-
ment. This radio is restricted to occupational use, work related operations only where the radio
operator must have the knowledge to control his or her RF exposure conditions.
When transmitting, hold the radio in a vertical position with its microphone 2 inches (5 cm) away
from your mouth and keep the antenna at least 2 inches (5 cm) away from your head and body.
The radio must be used with a maximum operating duty cycle not exceeding 50%, in typical Push-to-
Talk 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 P-T-T button.
SAR compliance for body-worn use was only demonstrated for the specific belt-clip Part Number
(#RA060190A). Other body-worn accessories or configurations may NOT comply with the FCC RF
exposure requirements and should be avoided.
Always use Vertex Standard authorized accessories.
