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 the terminal,
in locations with weak radio wave condition,
or out of Xi/FOMA service area. The services
may not be available on high upper floors of
high-rise apartments or buildings, even if you
can see 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 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- ppli.
