Safety Precautions (Be Sure to Read)
Do not perform transmission in a 
crowded place for the safety of per-
sons using a medical device such as 
a cardiac pacemaker.
The radio wave emitted from this prod-
uct can cause the medical device to mal-
function and result in an accident.
Do not touch any material leak-
ing from the battery pack with bare 
hands.
The chemical that has stuck to your skin 
or entered your eye can cause chemical 
burns. In such a case, consult the doctor 
immediately.
Do not solder or short-circuit the ter-
minal of the battery pack.
A fire, leak, overheating, explosion, or igni-
tion can result. 
Do not carry the battery pack together 
with a necklace, hair pin, or small metal 
objects. A short circuit can result.
If it starts thundering when the exter-
nal antenna is used, immediately turn 
off this product and disconnect the 
external antenna from it.
A fire, electrical shock, or damage may 
result. 
 WARNING
Do not power this transceiver with a 
voltage other than the specified pow-
er supply voltage.
A fire, electric shock, or damage may 
result.
Do not use the battery pack for any 
model other than the specified trans-
ceiver.
A fire, leak, overheating, explosion, or 
ignition can result.
This product has a waterproof struc-
ture and conforms to “IPX5” when 
the included antenna and battery 
pack are installed and rubber caps 
are securely attached to the MIC/SP 
jack, EXTDC IN jack, DATA terminal, 
and micro SD slot. If this transceiver 
gets wet, wipe it with a dry cloth, etc. 
do not leave it exposed to the mois-
ture.
Leaving this product in a wet condition 
can degrade its performance, shorten its 
life, or cause a failure or electrical shock.
Do not make very long transmissions.
The main body of the transceiver may 
overheat, resulting in a failure or burns.
Do not disassemble or make any al-
teration to this product.
An injury, electric shock, or failure can 
result.
Do not handle the battery pack or 
charger with wet hands. Do not insert 
or remove the power plug with wet 
hands.
An injury, leak, fire, or failure can result.
If smoke or strange odor is emitted 
from the main body, battery pack, 
or battery charger, immediately turn 
the transceiver off; remove the bat-
tery pack, and remove the power plug 
from the outlet.
A fire, leak, overheating, damage, igni-
tion, or failure can result. Contact the 
dealer from which you purchased this 
product or Yaesu Amateur Customer 
Support.
Do not use the battery pack which is 
externally damaged or deformed.
A fire, leak, heating, explosion, or igni-
tion can result.
Do not use any battery charger which 
is not specified by Yaesu.
A fire or failure can result.

Safety Precautions (Be Sure to Read)
Keep the terminals of the battery 
pack clean.
If terminal contacts are dirty or corroded, 
a fire, leak, overheating, explosion, or 
ignition can result.
If charging of the battery pack can-
not be completed within the specified 
charging time, immediately remove 
the power plug of the battery charger 
from the outlet.
A fire, leak, overheating, explosion, or 
ignition can result.
 CAUTION
Do not dangle or throw this product 
by holding its antenna.
This product can hit and injure some-
one. In addition, doing so can result in a 
transceiver failure or damage.
Do not use transceiver in a crowded 
place.
The antenna can hit someone, resulting 
in a injury.
Do not place this transceiver in a 
place subject to direct sunlight or 
near a heater.
The transceiver can deform or discolor.
Do not place this transceiver in a hu-
mid or dusty place.
A fire or failure can result.
During transmission, keep the anten-
na as far from you as possible.
Long-time exposure to electromagnetic 
waves can have a negative impact on 
your health.
Do not clean the case with thinner or 
benzene.
Use a soft, dry cloth to clean the case.
If you do not use this transceiver for a 
long period, turn it off and remove the 
battery pack for safety.
Do not drop, strike, or throw the 
transceiver.
A failure or damage may result.
Keep magnetic cards and video tape 
away from the transceiver.
The data recorded on cash cards or 
video tape can be erased.
Do not use the earpiece microphone, 
earphones, or headphones at an ex-
tremely high volume level.
Hearing impairment can result.
Keep this product out of reach of chil-
dren.
An injury, etc. can result.
Install the hand strap and belt clip 
securely.
If they are installed improperly, the 
FT1XDR/DE may fall or drop, resulting 
in an injury or damage.
Do not place a heavy object on the 
power cord of the battery charger.
The battery cord can be damaged, re-
sulting in a fire or electric shock.
Do not use the included battery char-
ger to charge any battery pack which 
is not specified for use with the char-
ger.
A fire can result.
Do not operate the transmitter near 
the TV or radio.
Radio disturbance can occur in the 
transceiver, the TV, or the radio.
Do not use any products other than 
the specified options and accesso-
ries.
A failure can result.
When the battery charger is not in 
use, remove its power plug from the 
outlet

Safety Precautions (Be Sure to Read)
Charge the battery pack within the 
temperature range from +5 °C to  
+35 °C (+41 °F to +95 °F).
Charging the battery pack outside this 
temperature range can cause leak, 
overheating, decrease in performance, 
or reduction in service life can result.
When unplugging the power cord of 
the battery charger, be sure to hold 
the power plug.
Pulling the power cord can damage it 
and cause a fire or electronic shock.
Before discarding the worn battery 
pack, affix tape or the like to its ter-
minals.
Before using this transceiver in a 
hybrid or fuel-saving car, be sure to 
check with the automobile manufac-
turer regarding use of the transceiver 
in that car.
Noise generated by an onboard electri-
cal device (inverter, etc.) can disrupt the 
normal operation of the transceiver.
