◎
Connections between the product and all other Bluetooth
®
and wireless LAN (Wi-Fi
®
) devices have not been
confirmed. Therefore, connections with all Bluetooth
®
and
wireless LAN (Wi-Fi
®
) devices are not guaranteed.
◎
This product supports security features for wireless
communications that are compliant with the Bluetooth
®
and wireless LAN (Wi-Fi
®
) standard specifications, but the
security may not be sufficient depending on the usage
environment and configuration. Be careful when making
data communication using Bluetooth
®
or wireless LAN
function (Wi-Fi
®
).
◎
Wireless LAN (Wi-Fi
®
) has the advantage that it can be
freely connected anywhere within the radio wave range,
as it uses radio waves for exchanging information.
However, not making security settings allows the risk of
malicious use by third parties. While at the customer's
discretion and responsibility, it is recommended that you
make security settings before using the product.
◎ The Company assumes no responsibility for leakage of
data or information that may occur during Bluetooth
®
/
wireless LAN (Wi-Fi
®
) communication.
◎
Since Bluetooth
®
and wireless LAN (Wi-Fi
®
) functions use
the same frequency band, using the both functions at
the same may cause radio wave interference resulting in
decreased communication speed or disconnection from
the network. If connection fails, stop using either of the
Bluetooth
®
and wireless LAN (Wi-Fi
®
) functions.
Bluetooth
®
and wireless LAN (Wi-Fi
®
) functions of the
product use frequencies in the 2.4 GHz band.
• Bluetooth
®
function: 2.4FH1/XX1
2.4FH1/XX1
This product uses the 2.4 GHz band. FH-SS is used
as the modulation scheme. The interference distance
is about 10 m or less.
• Wireless LAN (Wi-Fi
®
) function: 2.4DS4/OF4
This 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.
This means that all bandwidths are used, and that
band of mobile unit identification devices can be
avoided.
Available channels vary depending on countries.
For use in an airplane, check with the airline company
in advance.
