Important Notice!
FCC RF Exposure Compliance Requirements for Occupational Use Only:
The
FTA-750L/FTA-550/FTA-450L
have been tested and comply with the Federal Communications Commission (FCC)
RF exposure limits for Occupational Use/Controlled Exposure Environment. In addition, both radios comply 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 Frequency
Electromagnetic Fields, 3 kHz to 300 GHz.
ANSI/IEEE C95.3-1992, IEEE Recommended Practice for the Measurement of Potentially Hazardous Electromag-
netic Fields - RF and Microwave.
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 knowl-
edge 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 (2.5 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
“
TX
”
icon is displayed on the upper left corner of the screen of the radio.
You can cause the radio to transmit by pressing the PTT button.
Always use YAESU authorized accessories.
