Bluetooth function precautions
■ To secure the Bluetooth communication security, the terminal
supports the security function compliant with Bluetooth standards,
but the security may not be sufficient depending on the settings.
Be aware of the communication using the Bluetooth function.
■ Note that DOCOMO is not responsible for data or information leak
when making data communications using Bluetooth.
■ Frequency band
The frequency band used by the terminal's Bluetooth function/Wi-Fi
function is indicated on the battery storage section. The following are
the descriptions:
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 80 m 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 beforehand.
■ Cautions on using Bluetooth devices
The operating frequency band of the terminal is used by industrial,
scientific, consumer and medical equipment including microwave
ovens, premises radio stations for identifying mobile units used in
the manufacturing lines of plants (radio stations requiring a license),
specified low power radio stations (radio stations requiring no license)
and amateur radio stations (hereinafter referred to as "another
station").
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) uses radio waves to enable communications
between compatible devices, thus allowing connection to a local
area network from anywhere within the range. On the other hand,
there is a risk of data interception, etc. by third party unless
security is established. It is recommended to set the security
settings on your own responsibility.
■ Wireless LAN
Do not use wireless LAN near magnetic devices such as electrical
appliances or AV/OA devices, or in radio waves.
• Magnetism or radio waves may increase noises or disable
communications, etc. (especially when using a microwave oven).
• When used near TV, radio, etc., reception interference may occur, or
channels on the TV screen may be disturbed, etc.
• If there are multiple wireless LAN access points nearby and the same
channel is used, search may not work correctly.
• 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.
■ Cautions on using 2.4 GHz devices
The operating frequency band of the WLAN device is used by home
electric appliances such as microwave oven, industrial, scientific,
consumer and medical equipment including premises radio stations
for identifying mobile units used in the manufacturing lines of plants
(radio stations requiring a license), specified low power radio stations
(radio stations requiring no license) and amateur radio stations (radio
stations requiring a license).
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
stations for identifying mobile units, immediately change the
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.
