Notes on Using Bluetooth
®
/Wireless
LAN (Wi-Fi
®
) Functions
Frequency Band
Bluetooth
®
and wireless LAN (Wi-Fi
®
) functions (2.4 GHz band) of the
product use frequencies in the 2.4 GHz band ranging from 2.402 GHz
to 2.480 GHz.
The frequency bands used by this product’s Bluetooth
®
and wireless
LAN (Wi-Fi
®
) functions are given on the sticker located in the battery
compartment.
•
Bluetooth
®
function: 2.4FH1/XX4
The product uses the 2.4 GHz band.
FH1 uses FH-SS as the modulation scheme. The interference
distance is about 10 m or less.
XX4 uses other schemes. The interference distance is about 40 m or
less.
Bands of mobile unit identification devices cannot be avoided.
•
Wireless LAN (Wi-Fi
®
) function: 2.4DS/OF4
The product uses the 2.4 GHz band.
DS-SS and OFDM are used as the modulation schemes. The
interference distance is about 40 m or less.
Bands of mobile unit identification devices can be avoided.
Channels available with the 2.4 GHz band wireless LAN (Wi-Fi
®
) of
the product are between 1 to 13.
Available channels differ depending on the country.
For use in airplane, check with the airline company in advance.
Precautions about Bluetooth
®
•
The Bluetooth
®
function of the product conforms to the domestic
standards of Japan and FCC standards and EC directives, and has
been certified.
•
The 2.4 GHz band used by wireless LAN (Wi-Fi
®
) and Bluetooth
®
devices is shared by various other devices. For this reason,
Bluetooth
®
devices use technologies for minimizing effects from
other devices using the same radio frequency band. In some cases,
however, the communication speed and connectable range may be
decreased, or disconnection may occur, due to interference by other
devices.
•
The communication speed and connectable range vary depending
on the distance between communication devices, obstacles and the
Bluetooth
®
devices used.
■
Bluetooth
®
function precautions
The frequencies used by the Bluetooth
®
function of the product are in
the 2.4 GHz band. In this frequency band, in addition to home
electrical appliances such as microwave ovens and industrial,
scientific and medical devices, other similar wireless stations, in-plant
wireless stations for mobile unit identification that require a license for
use such as factory production lines, specific small power wireless
stations that do not require licenses, and amateur wireless stations
(collectively called “other wireless stations” from here on) are
operated.
1. Before using the product, make sure that “other wireless stations”
are not in operation nearby.
2. In the event that instances of radio wave interference have
occurred between the product and “other wireless stations”,
immediately either relocate the product or stop operation of the
device (stop emission of radio waves).
3. If you are unclear on any points or are troubled by anything,
contact an au shop or Customer Service Center.
