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 Eects 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
congurations. 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.
NOTICE
There are no user-serviceable points inside this transceiver.
All service jobs must be referred to your Authorized Service Center.

The YAESU FTA-750L/FTA-550/FTA-450L are compact, stylish, solid hand-held transceivers providing communica-
tion (transmit and receive) capability on the International Aircraft Communication Band (“COM” band: 118 to 136.975
MHz).
FTA-750L/FTA-550 are additionally provide VOR and ILS navigation features on the “NAV” band (108 to 117.975
MHz).
The FTA-750L/FTA-550/FTA-450L boast a 1.7” x 1.7” (43.2 x 43.2 mm) full dot matrix LCD displaying a plenty of
information in a row. The FTA-750L/FTA-550/FTA-450L include NOAA weather band monitoring and 200 memory
channels. The channel congurations can be easily reprogrammed in minutes using the optional PC Programming Soft-
ware and your PC. In addition, the FTA-750L provides positioning and navigation features realized by the internal GPS
unit.
We recommend that you read this manual in its entirety, so as to understand the many features of the FTA-750L/FTA-
550/FTA-450L completely. Keep this manual handy, so you may use it for reference.
Note: The VOR, ILS, and GPS navigation features of the FTA-750L/FTA-550 are for supplemental aids to naviga-
tion only, and are not intended to be a substitute for accurate (primary) VOR or landing service equipment.
You assume full responsibility for the use of the FTA-750L/FTA-550.

Battery Installation and Removal
To install the battery, insert the battery pack SBR-
39LI into the battery compartment on the back of the
transceiver , press the end of the battery pack while
pressing the battery pack latch on the bottom of the
transceiver , then lock the pack by sliding the locking
plate beside the latch until the entire “LOCK” ap-
pears .
Note:
Be sure that the rubber gasket on the SBR-39LI is
not loose when inserting.
To remove the battery, turn the
transceiver o, slide
the locking plate until the “UNLOCK” appears en-
tirely , lift up the end of the battery pack by pressing
the battery pack latch, then pull out the battery from
the radio.

Do not attempt to open any of the recharge-
able Lithium-ion packs, as personal injury
or damage to the Lithium-ion pack could
occur if a cell or cells become accidentally short-
circuited.
Note:
To remove the battery pack after the belt clip SHB-11
is mounted (see Page 15), lift up the clip before you
press the battery pack latch.
Caution:
Risk of explosion if battery is replaced by an incorrect
typ.
Dispose of used batteries according to the instructions.

Before You Begin
You may insert the cable plug of the SAD-25
into the EXT DC jack located on the right side of
the transceiver directly. In this case, the “ ”
icon will appear in the top right corner of the
LCD display.

cator on the SBH-11 will glow.
A fully-discharged pack will be charged com-
pletely in 5.5 hours, and then the GREEN indica-
tor on the SBH-11 will glow.
It takes 10 hours for full charge with the SAD-
25 connected to the transceiver directly.
Important Notes:
The
SAD-25 is not designed to power the transceiv-
er for operation (transmission).
Do not leave the charger connected to the transceiver
for continuous periods in excess of 24 hours. Long
term overcharging can degrade the Lithium-ion bat-
tery pack and signicantly shorten its useful life.
If using a charger other than the SAD-25, SBH-11,
or if using a battery pack other than the SBR-39LI,
follow the appropriate instructions provided with the
charger/battery. Contact your Dealer if you have any
doubts about the appropriateness of the particular
charger or battery pack you intend to use.
Battery Charging
It is necessary to charge the Lithium-ion battery fully
before its rst use. Follow the procedure below:
1. Install the Lithium-ion battery pack onto the trans-
ceiver. Ensure that the transceiver is switched o.
2. Insert the cable plug of the SAD-25 Battery Char-
ger into the jack located on the back of the SBH-11
Charging Cradle, then plug the SAD-25 into the AC
line outlet.

Alkaline Battery Tray Installation
The supplied SBT-12 Battery Tray allows operation of
the FTA-750L/FTA-550/FTA-450L using six “AA”
size alkaline battery cells.
 When installing a cell, insert the (–) end rst, then
press in the (+) end so the cell snaps into place. Pay
attention to the polarity indicated inside the case.
SBT-12
Alkaline Battery Tray
The SBT-12 must not be used with re-
chargeable cells. The SBT-12 does not con-
tain the thermal and over-current protec-
tion circuits required when utilizing Ni-Cd and Ni-
MH cells.
Note: Replace all six cells at the same time in case of
low battery.
To install the SBT-12, remove the Lithium-ion bat-
tery pack first from the transceiver, turn the open
side of the SBT-12 down, then insert it into the bat-
tery compartment.
Note: Be sure that the rubber gasket on the SBT-12
is not loose when inserting.
Low Battery Indication
As your battery discharges during use, the voltage
will gradually become lower. When the battery volt-
age reaches 6.0 Volts, the “ ” icon will blink on the
LCD display, indicating that the battery pack must be
recharged or the alkaline battery cells must be replaced
before further use.

Avoid recharging Lithium-ion batteries before the
“Low Battery” indicator is observed, as this can de-
grade the charge capacity of your Lithium-ion battery
pack. YAESU recommends that you carry an extra,
fully-charged pack with you so you will not lose
communications capability due to a depleted Lithi-
um-ion battery.
The fully-charged battery lasts for 12 hours on the
FTA-750L or 13.5 hours on the FTA-550/FTA-
450L under the conditions below:
Battery saver ... OFF
Operation ratio ... TX:RX:Standby = 6:6:48 (sec)

External DC Power Supply Connection
You may insert the cable plug of the optional SDD-12
Cigarette Lighter DC/DC Converter into the EXT DC
jack located on the right side of the transceiver. In this
case, the “ ” icon will appear in the top right corner
of the LCD display.
When making DC connections via the SDD-12, be ab-
solutely certain to observe the proper voltage level and
polarity guidelines.
The SDD-12 can be connected to 12 to 24 Volt DC
power sources.

Ferrite Core
Wind the cable one turn,
then snap two halves
As close
as possible
For noise reduction from exogenous noise, wind one
turn of the SDD-12 cable around the ferrite core,
and snap its two halves together, per the illustration
above. Attach the ferrite core as close as possible to
the SDD-12 body, as shown.
Do not connect any accessory unapproved
by YAESU to supply DC power; otherwise
the FTA-750L/FTA-550/FTA-450L may
be damaged.
Antenna Installation
To attach the supplied antenna to the FTA-750L/
FTA-550/FTA-450L, grasp the base of the antenna
rmly, and exert a moderate “pinching” pressure on
the base as you press the antenna onto the radio’s an-
tenna connector. While exerting this pressure, rotate
the antenna clockwise 1/4 turn to lock the antenna in
place.
