◆ Bluetooth devices
・
This terminal is equipped with the security features,
that are compliant with Bluetooth standards for
communication via Bluetooth. However, depending on
the settings, there may not be enough security. Be
aware of security risks when using Bluetooth.
・
DOCOMO assumes no responsibility for any
information which may be leaked during
communication via Bluetooth.
・
You can use headset, handsfree, audio, keyboard, data
transfer, and serial port with the terminal. An audio/
video remote control may be available with an audio
device (only compatible Bluetooth devices).
・
Frequency bands
Frequency bands used by the terminal Bluetooth
function are as below.
a b
c
2.4FH1
d
a 2.4 : Radio equipment that uses the 2400 MHz band.
b FH : The modulation is the FH-SS method.
c 1 : The expected interference distance is 10 m or
shorter.
d
: All bandwidths between 2400 MHz
and 2483.5 MHz are used, and the bandwidth used by
mobile object identification devices cannot be
avoided.
Cautions on using Bluetooth devices
In the bandwidth used by this terminal, in addition to
home electric appliances such as a microwave oven
and industrial/scientific/medical devices, in-plant
radio stations used to identify mobile objects used in
production lines of a factory that require a license,
specified low power radio stations, or amateur radio
stations that do not require a license (hereafter "other
radio stations") can be in operation.
1. Before using this terminal, check whether other
radio stations are in operation in your
neighborhood.
2. If radio wave interference occurs between the
terminal and "other radio stations", use the
terminal in a different location or "Turn the power
OFF" to avoid the radio wave interference.
3. For details, contact "General Inquiries" on the last
page of this manual.
◆ Wireless LAN (WLAN)
・
Wireless LAN (WLAN) exchanges information using
radio waves, and allows you to freely establish LAN
connection if you are within an area where radio wave
reaches. On the other side, if you communicate without
appropriate security settings, communications may be
intercepted or hacked by malicious parties. It is
recommended to make necessary security settings on
your judgement and responsibility.
・
Wireless LAN
Do not use Wireless LAN in a place where magnetized by
electric products, AV, OA equipment, etc. or where
electromagnetic wave is generated.
- If magnetism or electrostatic noise affects the terminal,
noise may be increased or communication may not be
available (especially when using microwave oven, it
may affect the terminal).
- Using near TV or radio may cause poor reception or TV
screen may be blurred.
