About Usage Of The Terminal - Samsung SC-56C Instruction Manual

Precautions

About usage of the terminal

• The terminal supports 5G, LTE, W-CDMA, GSM/GPRS, and wireless LAN and
does not set SIM lock.
• Because your terminal uses wireless transmission, it may not function in
locations where it is difficult for radio waves to penetrate, such as tunnels,
underground passages and some buildings, in areas where radio waves are
weak, or out of 5G service area and LTE service area. Even when you are high
up in a tall building or condominium and nothing blocks your view outside, your
terminal may not be able to receive or transmit signals. Also, communication
may be interrupted even when using without moving while radio waves is
strong and four antenna marks is displayed on your terminal.
• Because your terminal uses radio waves to communicate, it is possible that a
third party may attempt to tap your calls. However, 5G, LTE, W-CDMA, GSM/
GPRS system automatically applies a confidential communication function to
all calls, so even if a third party could somehow tap a call, they only hear noise.
• The terminal encodes voice communication as digital data. When you are
operating your terminal while moving to a location subject to weaker radio
wave conditions, the transmitted digital data may not be correctly decoded
and as a result the decoded voice may differ somewhat from the actual voice.
• Keep the data that you registered in the terminal separately by noting down
periodically or saving to microSD card, PC, etc. Note that DOCOMO cannot
assume any responsibility for any loss of saved contents of data resulting from
malfunction, repair, changing of the model or other handling of the terminal.
• Therefore, verify the supplier and operating conditions of the apps or websites
before use them. Some user-installed apps or accessed websites may give
the terminal instability of this terminal operation, or may send your location
information or personal information to outside via the Internet and the
information may be used improperly.
• The terminal automatically performs communications for some functions, for
example, to synchronize data, check the latest software, maintain connection
with the server, etc.
Additionally, when you download apps or watch video etc., a large amount
of packet communication charges are executed. Therefore, it is highly
recommended to use packet pack or packet flat-rate service.
• Depending on apps or services you use, a packet communication charges may
be charged even if you perform Wi-Fi communication.
• The terminal internal storage or the microSD card does not have enough
memory, running apps may not work normally. In such case, delete saved data.
• In case of loss of the terminal, set the screen lock password, etc. to ensure
the security of the terminal (P.106).
• If you lose your terminal, change password and disable certification of online
service accounts from PC so that Google Services such as Gmail, Google Play,
and SNS, etc. should not be used by others.
