2.4GHz device cautions
･
The operating frequency band of the WLAN
device is used by industrial, scientific, consumer
and medical equipment including home electric
appliances such as microwave ovens, premises
radio stations for identifying mobile units used in
the manufacturing lines of plants (radio stations
requiring a license), specified low power radio
stations (radio stations requiring no license) and
amateur radio stations (radio stations requiring a
license).
- Before using the device, confirm that premises
radio stations for identifying mobile units,
specified low power radio stations and amateur
radio stations are not being operated nearby.
- If the device causes harmful radio interference
to premises radio stations for identifying
mobile units, immediately change the
frequency band or stop use, and contact
"General Inquiries" on the last page for crosstalk
avoidance, etc. (e.g. partition setup).
- If the device causes radio interference to
specified low power radio stations or amateur
radio stations, contact "General Inquiries" on
the last page.

designation of Inductive Reader/Writer
Communication Equipment stipulated
in the Radio Law.
They use 13.56 MHz frequency band. When the
other FeliCa or NFC reader/writer, P2P function is
used in the surroundings, keep the terminal away
sufficiently from them. Before using, confirm that
there are no radio stations using the same
frequency band nearby.
For use in an aircraft, contact the airline
beforehand. Some countries may restrict the use
of the function. Check the regulations of the
