FCC RF Exposure Compliance Requirements for Occupational Use Only
:
This Radio has been tested and complies with the Federal Communica-
tions Commission (FCC) RF exposure limits for Occupational Use/Con-
trolled 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, Evaluat-
ing 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.
ANSI/IEEE C95.3-1992, IEEE Recommended Practice for the Mea-
surement of Potentially Hazardous Electromagnetic Fields-RF and
Microwave.
This radio is NOT approved for use by the general population in
an uncontrolled environment. This radio is restricted to occupa-
tional use, work related operations only where the radio operator
must have the knowledge to control its RF exposure conditions.
When transmitting, hold the radio in a vertical position with its mi-
crophone 1 to 2 inches (2.5 to 5 cm) away from your mouth and keep
the antenna at least 1 inch (2.5 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 (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 ra-
dio is illuminated. You can cause the radio to transmit by press-
ing the PTT button.
DO NOT transmit when the radio is used in a “Body Worn” config-
uration. It must be used ONLY for (1) when there is a 1” - 2” (2.5 to
5 cm) distance from the body during transmitting, or (2) for moni-
toring purposes, using the speaker only, or (3) for carrying purposes.
Always use Vertex Standard authorized accessories.
