FCC RF Exposure Compliance Requirements for Occupational Use Only:
The
FTA-720
its 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 Hu-
man 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 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 (2.5 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
congurations. 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.
Always use Yaesu authorized accessories.
There are no user-serviceable points inside this transceiver. All service jobs must be referred to your Authorized Service Center.

Low Battery Indication
As you battery discharges during use, the volt-
age will gradually become lower. When the “

LCD display, the battery
pack must be recharged
before further use.
Avoid recharging Li-Ion batteries before the “Low
Battery” indicator is observed, as this can degrade
the charge capacity of your Li-Ion battery pack.
Yaesu recommends that you carry an extra, fullycharged pack with you so you will not lose communications capability due to a depleted Li-Ion battery.
This “deep cycling” practice will help to maintain
longer overall battery life after many recharging
cycles.
