Cautions on using 2.4 GHz devices
In the frequency band 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.
Cautions on using 5 GHz devices
Using wireless LAN built-into the terminal in 5.2/5.3 GHz
outside is prohibited by the Radio Law.
Channel numbers and frequency bands available in Japan
are as follows.
･
5.2 GHz band : 5,180 to 5,240 MHz (36, 38, 40, 44, 46, 48
Ch)
･
5.3 GHz band : 5,260 to 5,320 MHz (52, 54, 56, 60, 62, 64
Ch)
･
5.6 GHz band : 5,500 to 5,700 MHz (100, 102, 104, 108,
110, 112, 116, 118, 120, 124, 126, 128, 132, 134, 136, 140
Ch)

FeliCa and NFC reader/writer
・
FeliCa and NFC reader/writer and P2P function of the
terminal uses weak waves requiring no licenses for radio
stations.
・
It uses 13.56 MHz frequency band. When using other
reader/writer or P2P function in your surroundings, keep
the terminal away sufficiently from them. Before using,
confirm that there are no radio stations using the same
frequency band nearby.
・
To use in airplane, confirm with airline company in advance.
Use is limited in some countries.
Confirm regulations of the country/region to use it.
