Important notIce!
FCC RF Exposure Compliance Requirements for Occupational Use Only:
The FTA-310 has been tested and complies with the Federal Communications Commission (FCC) RF exposure lim-
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 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
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 upper right corner of the front panel of the radio is illu-
minated. You can cause the radio to transmit by pressing the P-T-T button.
Always use Yaesu authorized accessories.

IntroductIon
The YAESU FTA-310 is a compact, stylish, solid hand-held transceiver providing communication (transmit and re-
ceive) capability on the International Aircraft Communication Band (“COM” band: 118 ~ 136.975 MHz), and it addi-
tionally provides VOR and CDI navigation features on the “NAV” band (108 ~ 117.975 MHz).
The FTA-310 boasts 0.8 Watt of clean audio output from its 1.4” (36-mm) diameter loudspeaker, and it also provides
8.33 kHz synthesizer steps for the receiving of the new narrow-band channel plan. The FTA-310 includes both Tem-
perature and Supply Voltage displays with our exclusive Omni-GlowTM display back-lighting for minimal degradation
of your night vision, NOAA weather band monitoring, 8-character Alpha/Numeric Display, 150 Memory Channels, and
up to 100 “Book Memory” Channels. The channel congurations are can be easily reprogrammed in minutes using the
optional PC Programming Kit and your PC.
We recommend that you read this manual in its entirety, so as to understand the many features of the FTA-310 com-
pletely. Keep this manual handy, so you may use it for reference.
NOTE: The FTA-310’s VOR and CDI Navigation features are supplemental aids to navigation only, and are not in-
tended to be a substitute for accurate (primary) VOR/CDI or landing service equipment.
Congratulations!
You now have at your ngertips a valuable communications tool, a YAESU two-way radio! Rugged, reliable and
easy to use, your YAESU radio will keep you in constant touch with your friends and colleagues for years to come,

controls & connectors (top panel)
Antenna Jack
This BNC connector accepts the supplied flexible
antenna, or another antenna designed to provide 50
impedance on the Aircraft Communication Band.
MIC/EAR Jack
You may connect the supplied CT-96 Headset Cable
or the (optional) MH-44B4B Speaker/Microphone
to this jack. To use this jack, you must rst remove
the plastic cap by rotating it counter-clockwise, then
lifting it away from the transceiver body.
Do not allow the FTA-310 to become sub-
merged in water while the plastic cover
over the MIC/EAR jack is removed.
POWER/VOLUME (Inner) Knob
Turn this (inner) control clockwise to turn the radio
on and to increase the volume. Counterclockwise
rotation into the click-stop will turn the radio off.
Pressing this knob downward momentarily selects
the tuning methods among the VFO (Variable Fre-
quency Oscillator), MR (Memory Recall), BOOK
(Pre-Programmed Memories), and WX (Weather
Channel Memories) modes.
Note: The WX mode is available in the USA ver-
sion only.
DIAL Selector (Outer) Knob
This (outer) 20-position detented rotary switch tunes
the operating frequency or selects the memory chan-
nels.

BUSY/TX Indicator Lamp
This lamp glows green when a signal is being re-
ceived, and red when transmitting.
Loudspeaker
The internal speaker is located in this position.
Microphone
Speak across this opening in a normal voice level,
while pressing the PTT switch, to transmit.
LCD (Liquid Crystal Display)
The display shows selected operating conditions, as
indicated on the next page.
Keypad
The keypad is used for most radio command opera-
tions. Several keys have triple functions.
The primary functions are activated by simply
pressing the key momentarily.
The secondary functions are activated by pressing
the key followed by [F] key.
The third functions are activated by pressing and
holding in the key for 2 seconds.
These functions are described in detail on page 8.

PTT (Push To Talk) Switch
Press this button to transmit when you are operating
in the COM band. Release this button to return to
the “Receive” mode. See page 16 for details.
MONITOR Switch
This button may be pressed to “open” the squelch
manually, allowing you to listen for very weak
signals. Press and hold this button for 2 seconds
to “open” the squelch continuously. Press this but-
ton again to resume normal (quiet) monitoring. See
page 15 for details.
EXT DC Jack
When an external 12-Volt DC power source is avail-
able, you may connect the (optional) E-DC-5B Ex-
ternal DC Cable here.
1) Do not allow the FTA-310 to become
submerged in water while the rubber cover
is removed.
2) Do not connect any wire to this jack if that wire
is connected directly to a 28-Volt DC source. Con-
necting the FTA-310 directly to a source which
exceeds 15.0 Volts DC will result in damage to the
unit, and this type of damage is not covered by the
Limited warranty on this product.
