Using The Handset - Sharp AQUOS R3 SH-04L Instruction Manual

Using the handset

z The handset supports LTE, W-CDMA, GSM/GPRS 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 [ ] (indicating signal status) is displayed, 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,
W-CDMA and GSM/GPRS 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 information
to external memory devices such as microSD Cards and PCs
periodically. DOCOMO shall not be liable for any loss of content
due to a failure, repair, model change or other handling of the
handset.
z As with PCs, some user-installed apps, user-accessed websites,
etc. may disrupt the stability of your 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 the apps, websites, etc. 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,
making a communication with large-volume data such as
downloading apps or watching videos will lead to higher packet
communication charges. Subscription to Packet Pack/flat-rate
packet communication services is highly recommended.
z Even while the Wi-Fi connection is set, packet communication
charges may be incurred depending on the app and service you
use.
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 Secure the security of the handset by setting the password of
Screen lock in case you lose it.
z If your handset is lost, change your password for each service
account and disable authentication using a PC to prevent other
persons from using Google services such as Gmail and Google
Play™, SNS, etc.
z For using services and apps provided by a third party including
Google LLC, check the terms of service of Google or the
respective providers, etc. DOCOMO shall not be liable for any
failure caused by related services and apps.
