･ The terminal supports LTE, W-CDMA, GSM/GPRS and Wireless
LAN Systems.
･ Because the terminal operates using radio frequencies, it may not
be able to use 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
terminal may not be available even when you are on the upper floors
of high-rise apartments or buildings without any obstructions for
your view. Calls may be disconnected even when you use the
terminal staying in areas with strong radio wave condition with
icon appeared.
･ 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 communicates via radio waves by converting voice
into digital signals. If you move into an area of poor radio wave
condition, the digital signal may not be reconverted accurately, and
the voice received in the call may differ slightly from the actual one.
･ Maintain a separate record of the data saved in the terminal by
taking notes periodically or saving in the external memory 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 or accessed
websites may disrupt the stability of your 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. Please thoroughly check providers and
operation status of the applications, websites, etc. which you want
to use beforehand and then use it.
･ This terminal supports FOMA Plus-Area and FOMA HIGH-SPEED
Area.
･ You can use the terminal only with a docomo nano UIM card. If you
have a docomo mini UIM card, docomo UIM card, or FOMA card,
bring it to a docomo Shop to replace it with a docomo nano UIM
card.
･ Public mode (Driving mode) is not supported.
･ 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, the 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.
･ You can update software on the terminal to the latest one. → P.131
･ Updates for improving the quality of the terminal or upgrade of
operating system (OS) may be performed. And some applications
that used in the previous OS version may not be available or some
unintended bugs may occur after the upgrade.
