･
The terminal supports LTE, W-CDMA, GSM/
GPRS and Wireless LAN Systems.
･
Because a terminal operates using radio
frequencies, it cannot be used inside a tunnel,
underground, in a building or other locations
where radio waves do not reach the terminal,
in locations with weak radio wave condition,
or out of Xi/FOMA service area. The services
may not be available on the upper floors of
high-rise apartments or buildings, even if
there are no obstructions around you. On
occasion, your calls may become
disconnected even in areas with strong radio
wave condition, even if you are not moving, or
even if there are 4-signal icon in the terminals
display.
･
Because your terminal uses radio waves to
communicate, it is possible that a third party
may attempt to tap your calls. However, the
LTE, W-CDMA, GSM/GPRS system
automatically scrambles all calls through a
private call feature. Therefore, even if the third
party successfully intercepts your call, they
will only hear noise.
･
The terminal operates on radio frequencies by
converting voice into digital signals. If the
caller moves into an area of adverse radio
wave condition, the digital signal may not be
restored accurately, and the voice received in
the call may differ slightly from the actual
voice.
･
Note down the information saved in the
terminal in a separate note on a regular basis
or save to an external recording medium such
as a microSD card or PC. Note that DOCOMO
assumes no responsibility for any loss of saved
contents of data resulting from malfunction,
repair, changing of the model or other
handling of the terminal.
･
As with PCs, some user-installed applications
may disrupt the stability of the terminal
performance, or unexpectedly transmit
information via the Internet causing improper
use of your location information as well as
personal information recorded on the
terminal. Therefore, verify the supplier and
operating conditions of the applications to be
used before using them.
･
This terminal has FOMA Plus-Area and FOMA
HIGH-SPEED Area support.
･
The terminal does not support i-mode sites
(programs) or i-
D
ppli.
About using the terminal

6
Contents/Precautions
･
The terminal automatically performs
communication for synchronizing data,
checking the latest software version, and
maintaining a connection with the server, and
for other purposes. If you transmit a large
amount of data, such as when downloading
applications or watching video, a packet
communication charge becomes high.
Subscription to Packet Pack/packet flat-rate
service is highly recommended.
･
Depending on the applications or service you
use, packet communication charge may be
applied even in Wi-Fi communication.
･
Public mode (Driving mode) is not supported.
･
Setting the terminal to silent mode does not
mute sounds for shutter, playback of video or
music, dialpad operation sound during a call
or sound emitted when is tapped, etc.
･
The name of the operator is displayed on the
lock screen (P.40).
･
To check your phone number (own number),
from the Home screen,
u

u
[About phone]
u
[Status] to
see "My phone number".
･
To check the software version, from the Home
screen,
u

u
[About phone].
･
If available memory in the microSD card or
the terminal is low, running applications may
not operate correctly. In that case, delete the
saved data.
･
You can update software on the terminal to
the latest one (P.208, P.211).
･
The operating system (OS) may be upgraded
via software updates to improve the quality of
the terminal. For this reason, you always need
to use the latest OS version. And some
applications that used in the previous OS
version may not be available or some
unintended bugs may occur.
･
You can use the terminal only with a docomo
nano UIM card. If you have a docomo mini
UIM card, UIM, or FOMA card, bring it to a
docomo Shop to replace it with a docomo
nano UIM card.
･
Set password etc. for screen lock to ensure the
security of your terminal for its loss (P.167).
･
If your terminal is lost, change your each
account password to invalidate
authentication using a PC to prevent other
persons from using Google services such as
Gmail or Google Play, or SNS, etc.
･
For services provided by Google, refer to
Google Terms of Service. For other web
services, refer to each terms of service.
･
Applications and service contents are subject
to change without prior notice.
･
The terminal supports only sp-mode, mopera
U and Business mopera Internet. Other
providers are not supported.
･
To use tethering, subscription of sp-mode is
required.

7
Contents/Precautions
･
If you want to use tethering, subscription to
Packet Pack/packet flat-rate service is strongly
recommended.
･
For details on usage charge, refer to NTT
DOCOMO website.

4. Handling the docomo nano UIM
card
CAUTION
Be careful of the cut surface when handling
a docomo nano UIM card.
Failure to do so may cause injury.
5. Handling the terminal near
electronic medical equipment
WARNING
If you use an implantable cardiac pacemaker
or implantable cardioverter defibrillator,
keep the terminal 15 cm or more away from
the implant at all times.
The radio waves from the terminal may affect
the performance of electronic medical
equipment.
If you need to use electronic medical
equipment other than implantable cardiac
pacemaker or implantable cardioverter
defibrillator outside medical facilities such
as treating at home, check with the relevant
medical electronic equipment manufacturer
whether the operation may be affected by
radio waves.
The radio waves from the terminal may affect
the performance of electronic medical
equipment.
When you get close to other people within
15 cm just like not having enough space to
turn around, set the radio wave of the
terminal to OFF beforehand (Airplane mode,
to Power off, etc.).
A person in close proximity may put on
implanted a medical electrical equipment
such as pacemakers and ICDs. The radio waves
from the terminal may affect the performance
of electronic medical equipment.
Follow the instructions of each medical
facility for the use of the terminal on their
premises.

SO-04G is waterproof/dustproof;
however, do not allow water or dust to
enter the terminal or come in contact
with accessories or optional devices.
The adapter, desktop holder, docomo nano UIM
card and 1Seg antenna cable are not waterproof/
dustproof. Do not use in a bathroom or other
highly humid area or do not let rain touch. Or
putting them on your body, humidity of sweat
may cause internal corrosion and malfunction.
Note that malfunctions which are determined to

Contents/Precautions
･
Clean the terminals occasionally with a
dry cotton swab.
If the jack is soiled, connection gets worse and it

･
Make sure to use the terminal etc.
without excessive force.
If you put the terminal in a bag full of items or sit
down with the terminal in the pocket of your
cloth, it may damage the display, internal circuit
board, etc. and cause malfunction.
If doing so while the external device is connected
to the microUSB jack or headset jack, it may
cause damage or malfunction.
･
Do not rub or scratch the display with
metal.
The display may get scratched and it may cause
malfunction or damage.
