Cautions on using Bluetooth devices
In the bandwidth used by this terminal, in addition to home
electric appliances such as a microwave oven and industrial/
scientific/medical devices, in-plant radio stations used to
identify mobile objects used in production lines of a factory
that require a license, specified low power radio stations, or
amateur radio stations that do not require a license
(hereafter "other radio stations") can be in operation.
1. Before using this terminal, check whether other radio
stations are in operation in your neighborhood.
2. If radio wave interference occurs between the
terminal and "other radio stations", use the
terminal in a different location or "Turn the power
OFF" to avoid the radio wave interference.
3. For details, contact "General Inquiries" on the last
page of this manual.

Wireless LAN (WLAN)
・
Wireless LAN (WLAN) exchanges information using
radio waves, and allows you to freely establish LAN
connection if you are within an area where radio wave
reaches. On the other side, if you communicate without
appropriate security settings, communications may be
intercepted or hacked by malicious parties. It is
recommended to make necessary security settings on
your judgement and responsibility.
・
Wireless LAN
Do not use Wireless LAN in a place where magnetized by
electric products, AV, OA equipment, etc. or where
electromagnetic wave is generated.
- If magnetism or electrostatic noise affects the terminal,
noise may be increased or communication may not be
available (especially when using microwave oven, it
may affect the terminal).
- Using near TV or radio may cause poor reception or TV
screen may be blurred.
- When multiple wireless LAN access points exist near
the terminal and they use the same channel, search
may not be performed correctly.
・
Frequency bands
Frequency bands used by WLAN devices are as below.
Frequency bands : 2400 MHz band
Modulation : DS-SS method, OFDM method
Expected interference distance : 40 m or shorter
Frequency changing possibility : All bandwidths
between 2400 MHz and 2483.5 MHz are used, and the
bandwidth used by mobile object identification devices
can be avoided.
Available channel varies by countries. To use WLAN
overseas, check the conditions such as available
frequency, regulation, etc. for the country.
To use in airplane, confirm with airline company in
advance.
Cautions on using 2.4 GHz devices
In the bandwidth used by WLAN devices, in addition
to home electric appliances such as a microwave oven
and industrial/scientific/medical devices, in-plant
radio stations for identification of mobile objects used
in production lines of a factory (a license is required),
specified low power radio stations (a license is not
required), or amateur radio stations (a license is
required) can be in operation.
1. Before using this device, confirm that in-plant radio
stations for identification of mobile objects, specified
low power radio stations or amateur radio stations are
not in operation in your neighborhood.
2. If this device generates harmful radio wave
interference against in-plant radio stations for
identification of mobile objects, change the using
frequency promptly or stop using wireless LAN
function, and contact "General Inquiries" on the last
page of this manual, then consult about treatment
for prevention of the interference (for example,
installation of partitions etc.).
3. If this device generates harmful radio wave
interference against in-plant radio stations for
identification of mobile objects or amateur radio
stations, or if any trouble, contact "General
Inquiries" on the last page of this manual.
