About usage of the terminal
• The terminal supports LTE, W-CDMA, GSM/GPRS, and wireless LAN.
• Since the terminal uses wireless signal, it may not be able to use in
a location with no signal reception such as a tunnel, underground, a
building, an outdoor location with weak or poor signal reception, or a
location outside of the LTE and FOMA service areas. Even when you are
high up in a tall building or condominium and nothing blocks your view
outside, your terminal may not be able to receive or transmit signals.
Also, communication may be interrupted even when the signal meter
on your terminal indicates there are strong radio waves and you are not
moving (traveling).
• Because your terminal uses radio waves to communicate, it is possible
that a third party may attempt to tap your calls. However, LTE, W-CDMA,
GSM/GPRS system automatically applies a confidential communication
function to all calls, so even if a third party could somehow tap a call,
they only hear noise.
• The terminal encodes voice communication as digital data. When you
are operating your terminal while moving to a location subject to weaker
radio wave conditions, the transmitted digital data may not be correctly
decoded and as a result the decoded voice may differ somewhat from
the actual voice.
• Keep the information that you registered in the terminal separately by
noting down periodically or saving to microSD card, PC etc. DOCOMO
assumes no responsibility for any loss of your data caused by
malfunction, repair, change to a new model or any other reasons. If the
data is deleted, DOCOMO assumes no responsibility for the loss of any
data.
• As with PCs, some applications that you install or websites that you
access may give the terminal instability of the operation, or may send
your location information or personal information registered to the
terminal to outside via the Internet and the information may be used
improperly. Therefore, verify the supplier and operating conditions of the
applications and websites before using them.
• The terminal automatically performs communication for some
functions, for example, to synchronize data, check the latest
software, maintain connection with the server, etc. Additionally, when
you download applications or watch video etc., a large amount of
packet communication charges are executed. Therefore, it is highly
recommended to use packet pack or packet flat-rate service.
• Depending on the applications or service you use, packet communication
charge may be applied even in Wi-Fi communication.
• If the microSD card or the terminal internal storage does not have
enough memory, running applications may not work normally. In such
case, delete saved data.
• In the terminal, functions may be added or operation steps may be
changed due to upgrading Operating System (OS). For latest information
of additional function or operation steps, refer to NTT DOCOMO website.
Also some applications used for former OS may not work or unintended
failure may occur.
• In case of loss of the terminal, set password, etc. for the screen lock to
ensure the security of the terminal. (P.113)
• If you lose your terminal, change password or disable authentication of
online service accounts from PC so that Google Services such as Gmail,
Google Play, or SNS, etc. should not be used by others.
• For using services and applications provided by the third party including
the applications provided by Google LLC, confirm the terms and
conditions specified by Google or the providers. DOCOMO assumes
no responsibility for any malfunctions resulting from the services and
applications.
• When the terms of use screen appears, follow the on-screen instructions.
• Applications or services are subject to change without prior notice.
• The terminal does not support service providers other than sp-mode,
mopera U or Business mopera Internet.
• For details on usage fee, refer to the NTT DOCOMO website.
• Although the display is manufactured with extremely advanced
technology, some dots may not be lit or be always lit. Note that, this
shows characteristics of liquid crystal displays and not defects in the
terminals.
• 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.
• For commercially available option devices, DOCOMO is not liable to any
failures or the malfunctions.
