About using the terminal
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.212).
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.
