Contents/Precautions
Contents/Pre cautions
･
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, in locations
with weak radio wave condition, or out of LTE/
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 be disconnected even in areas with
strong radio wave condition, even if you are
not moving, or even if there are 4-signal icon
on the terminal's display.
･
Because the 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 a caller
moves into an area of poor 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.
･
The terminal supports the function which
allows "User" or "Guest" to use the terminal.
Therefore some services or applications
recognize them as the same user even after
the user is switched. DOCOMO shall have no
liabilities for any damage or troubles of
customer or a third party resulting from using
the function (P.209).
･
Note down the data saved to 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 data
resulting from malfunction, repair, changing
of the model or other handling of the
terminal.
･
As with PCs, some user-installed applications
or accessed websites 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 or
websites before using them.
About using the terminal

5
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.
･
If available memory in the microSD card or
the internal storage is low, running
applications may not operate correctly. In that
case, delete the saved data.
･
The terminal may have a software update of
the operating system (OS) for the purpose of
quality improvement or addition of functions.
In that case, operation procedure may
change. For the latest information about
addition of functions or change of operation
procedure, refer to NTT DOCOMO website.
And some applications that used in the
previous OS version may not be available or
some unintended bugs may occur.
･
Set password etc. for screen lock to ensure the
security of your terminal for its loss (P.195).
･
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 using services and applications provided
by the third party's including applications
provided by Google LLC., confirm the terms
and conditions, etc. specified by Google or
the providers. DOCOMO assumes no
responsibility for any malfunctions resulting
from the services and applications.
･
When a license agreement screen etc.
appears, follow the onscreen instructions.
･
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.
･
For details on usage charge, refer to NTT
DOCOMO website.
･
Display is manufactured by taking advantage
of highly advanced technology but some
dots may be always or never lit. Note that, this
shows characteristics of the display and not
defects in the terminals.

6
Contents/Precautions
･
The terminal has an organic EL display.
Although an afterimage may occur when the
same image has been displayed for a long
time, it is not a malfunction. To prevent the
display from having afterimages, do not
display the same image for a long time. Also,
unevenness of colors or brightness, or
changes of colors may be found depending
on direction you are looking. That is because
of the structure of organic EL display, not a
malfunction.
･
DOCOMO is not liable to any failures or
malfunctions for commercially available
optional equipment.
