Important notICe!
FCC RF Exposure Compliance Requirements for Occupational Use Only:
The FTA-450L has been tested and complies with the Federal Communications Commission (FCC) RF exposure limits
for Occupational Use/Controlled Exposure Environment. In addition, the radio 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
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.

A fully-discharged pack will be charged com-
pletely in 4 hours, and then the GREEN indica-
tor on the SBH-11 will glow letting you know
the battery has been fully charged.
It takes 8 hours for full charge with the SAD-
11 connected to the transceiver directly.
Important Notes:
The
SAD-11 is not designed to power the trans-
ceiver for operation (transmission).
Do not leave the charger connected to the trans-
ceiver for continuous periods in excess of 24 hours.
Long term overcharging can degrade the Lithium-
ion battery pack and signicantly shorten its useful
life.
If using a charger other than the SAD-11, SBH-11,
or if using a battery pack other than the SBR-12LI,
follow the appropriate instructions provided with
the charger/battery. Contact your Dealer if you have
any doubts about the appropriateness of the particu-
lar 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 off.
2. Insert the cable plug of the SAD-11 Battery Char-
ger into the jack located on the back of the SBH-11
Charging Cradle, then plug the SAD-11 into the AC
line outlet.

Alkaline Battery Tray Installation
The supplied SBT-12 Battery Tray allows operation
of the 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 protection cir-
cuits 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 voltage
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
degrade 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
Lithium-ion battery.
The fully-charged battery lasts for 13.5 hours on the
FTA-450L under the conditions below:

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.
Do not connect any accessory unapproved
by YAESU to supply DC power; otherwise
the FTA-450L may be damaged.
Antenna Installation
To attach the supplied antenna to the 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 antenna con-
nector. While exerting this
pressure, rotate the antenna
clockwise 1/4 turn to lock the
antenna in place.

Precautions
The
FTA-450L is capable of two-way communica-
tion on channels used for critical aviation safety
communications. Therefore, it is important that this
radio be kept away from children or other unauthor-
ized users at all times.
Do not dispose of the Lithium-ion battery pack in a
re. Do not carry a Lithium-ion battery pack in your
pocket, where keys or coins could short the termi-
nals. This could create a serious fire/burn danger,
and possibly cause damage to the Lithium-ion pack.
The
FTA-450L is designed to have the waterproof
capability equivalent to IPX5. Do not allow the ra-
dio to become submerged, and do not subject it to
water spray under pressure.
