Bluetooth function
■ The 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.
■ Frequency bands
The frequency band used by the terminal's Bluetooth function/Wi-Fi
function is storage section is as follows.
2.4 FH1 / DS4 / OF4 / XX8
2.4 : This radio equipment uses the 2400 MHz band.
FH/DS/OF/XX : Modulation scheme is FH-SS, DS-SS, OFDM or other
scheme.
1 : The estimated interference distance is 10 m or less.
4 : The estimated interference distance is 40 m or less.
8 : The estimated interference distance is 80m or less.
: The full band between 2400 MHz and 2483.5 MHz
is used and the band of the mobile identification
device is unavoidable.
Available channels vary by the country.
For use in an aircraft, contact the airline company beforehand.
■ Cautions on using Bluetooth devices
In the bandwidth used by the 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 the terminal, confirm that "another station" is not being
operated nearby.
2. In the event of the terminal causing harmful radio wave interference
with "another station", promptly change the operating frequency or
stop radio wave emission by turning off the power, etc.
3. If you have further questions, contact docomo Information Center
provided on the last page of this manual.
Wireless LAN (WLAN) precautions
■ 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. At the same time, there is a
risk that a malicious third party may obtain unauthorized access if
security settings have not been configured. You are recommended
to configure security settings before using wireless LAN at your
decision and responsibility. It is recommended to make necessary
security settings on your judgment and responsibility.
■ Wireless LAN
Do not use wireless LAN in a place that is magnetized by electric
products, AV, OA equipment, etc. or where electromagnetic wave is
generated.
• Subjecting the terminal to magnetic or electrical noise might increase
noise and prevent it from performing communications. (the terminal
is particularly susceptible to noise when it is used near a microwave
oven.)
• Using the terminal near a TV, radio or similar appliance might cause
reception interference and disrupt TV images.
• The searching might not be successful if there are multiple wireless
LAN access points near to the terminal or the same channel is being
used.
• For using WLAN overseas, point of use etc. may be restricted
depending on country. In that case, confirm conditions such as
available frequency or regulations of the country to use it.
■ 2.4 GHz device cautions
In the frequency band used by WLAN devices, in addition to home
electric appliances such as a microwave oven and industrial/scientific/
medical devices, in-plant radio stations for identification of mobile
objects used in production lines of a factory (a license is required),
specified low power radio stations (a license is not required), or amateur
radio stations (a license is required) can be in operation.
1. Before using the device, confirm that premises radio stations for
identifying mobile units, specified low power radio stations and
amateur radio stations are not being operated nearby.
2. If the device causes harmful radio interference to premises radio
s t a t i o n s f o r i d e n t i f y i n g m o b i l e u n i t s , i m m e d i a t e l y c h a n g e t h e
frequency band or stop use, and contact "docomo Information Center"
described on the last page of this manual for crosstalk avoidance,
etc. (e.g. partition setup).
3. If the device causes radio interference to specified low power radio
stations or amateur radio stations, contact "docomo Information
Center" described on the last page of this manual.
