/Wireless
LAN (Wi-Fi
®
) Functions
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
connected devices used.
Precautions about Wireless LAN (Wi-Fi
®
)
•
The wireless LAN (Wi-Fi
®
) function of the product conforms to the
domestic standards of Japan, FCC standards and EC directives,
and has been certified.
•
Do not use the product in places where electromagnetic waves are
generated or near electric products, AV and OA equipment, or other
magnetized devices.
•
Subjecting the product to magnetic or electrical noise might increase
noise and prevent it from performing communications. (The product
is particularly susceptible to noise when it is used near a microwave
oven.)
•
Using the product near a TV, radio or similar appliance might cause
reception interference and disrupt TV images.
•
Searching might not be successful if there are multiple wireless LAN
(Wi-Fi
®
) access points near the product and the same channel is
being used.
•
The communication speed and connectable range vary depending
on the distance between communication devices, obstacles and the
connected devices used.
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.
