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 and keep it safely.
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.
･
You are recommended to save important
data to microSD card.
･
As with PCs, some user-installed applications
may disrupt the stability of the terminal

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.
