recautions
• 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. 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 use at your decision
and responsibility.
• 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.
Bands of mobile unit identification devices cannot be avoided.
• 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 bands
of mobile unit identification devices can be avoided.
Available channels vary depending on countries.
For use in airplane, check with the airline company in advance.
Cautions on using 5GHz band
Wireless LAN (Wi-Fi
®
) function of this product uses 5 GHz
band. Using 5.2 GHz band and 5.3 GHz band outdoors is
prohibited by the Radio Law.
The channels used on the product are as follows.
W52 (5.2 GHz band/36, 38, 40, 44, 46, 48 ch)
W53 (5.3 GHz band/52, 54, 56, 60, 62, 64 ch)
W56 (5.6 GHz band/100, 102, 104, 108, 110, 112, 116, 118,
120, 124, 126, 128, 132, 134, 136, 140 ch)
