Introduction
Thank you for your purchase of "SO-03D".
For proper use of the SO-03D, read this manual carefully before and while you use the SO-03D.
Before using the terminal
●
SO-03D supports 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 outside of the FOMA's 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-antenna marks in the terminal's display.
●
Note that because the terminal operates on radio frequencies, your calls are at risk of being intercepted by
the third party. However, the 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. Even if the data
may be lost as a result of malfunction, repair, change, or other handling of the terminal, under no
condition will DOCOMO be held liable for any lost data saved in 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 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.
●
Descriptions in this manual are fore the terminal with a DOCOMO's UIM inserted.
