Using the handset
z
The handset supports LTE, W-CDMA, and wireless LAN
systems.
z
Because the handset relies on radio signals, it cannot
be used in a place with no signal (such as tunnels,
underground or in buildings), in places with a weak
signal or outside the LTE service area or FOMA service
area. You may not use the handset in the upper floors
of a building even with no obstructions in sight. There
may also be times when the signal is strong and you
are not moving but the call is interrupted.
z
Because the handset uses radio waves, it is possible
for a third party to listen in on a conversation. However,
since the LTE and W-CDMA systems automatically
apply a private call feature to every call, a third party
that tries to listen in only hears noise.
z
The handset converts conversations into a digital
signal and sends it to the other party over the radio. If
the signal cannot be reconverted properly by such as
moving to an area with a weak signal, the voice may
not be heard correctly.
z
Take notes of data stored on the handset or save the
data to external memory devices such as microSD
cards and PCs periodically. DOCOMO shall not be liable
whatsoever for any loss of content due to a failure,
repair, model change or other handling of the handset.
z
As with PCs, some user-accessed sites may disrupt
the stability of handset performance or unexpectedly
transmit information via the Internet causing improper
use of your location information, personal information
stored on the handset, etc. Therefore, verify the
supplier and operating conditions of sites to be used
before using them.
z
The handset automatically performs communication for
some functions, for example, to synchronize data,
check the latest software version or maintain
connection with the server. Also, large-volume data
communication such as watching videos will lead to
higher packet communication charges.
z
Depending on the apps or services you are using,
packet communication charges may be incurred even
while using Wi-Fi.
z
When the available space on the microSD card or the
handset is insufficient, apps in use may not work
properly. In this case, delete saved data.
z
Ensure the security of your handset by setting a
screen lock password in case you lose it (→P. 104).
z
If terms of use appear, follow the instructions on the
screen.
z
Apps and their service contents are subject to change
without prior notice.
z
The handset does not support providers other than
sp-mode, mopera U and Business mopera Internet.
