Bluetooth
/Wi-Fi (WLAN)
®
Connection/operation may not be possible with some
Bluetooth
/Wi-Fi (wireless LAN) devices.
®
Handset Bluetooth
/Wi-Fi (wireless LAN) communication is
®
secured in conformity with Bluetooth
standards, however, security may be insufficient depending on
system environment and settings. Be aware of this when using
Bluetooth
/Wi-Fi (wireless LAN) communication.
®
SoftBank Corp. is not responsible for damages from leakage of
data or information occurring using Bluetooth
LAN) communication.
Frequency Bands (2.4 GHz Band)
Frequency band used by handset Bluetooth
functions are as follows:
2.4: Frequency band is 2400 MHz
FH/XX/DS/OF: Modulations are FH-SS, other modulation, DS-
SS, OFDM
4: Estimated range of radio frequency interference is up to
40 m
8: Estimated range of radio frequency interference is up to
80 m
: Utilizes 2,400 MHz to 2,483.5 MHz band
without mobile device bandwidth differentiation
・Available channels may vary by country.
・For use in an airplane, contact your airline.
Frequency Bands (5 GHz Band)
In 5 GHz frequency bandwidth, handset can use 5.2 GHz
(W52), 5.3 GHz (W53), and 5.6 GHz (W56) bands.
・5.2 GHz band (W52/36, 40, 44, 48 ch)
・5.3 GHz band (W53/52, 56, 60, 64 ch)
・5.6 GHz band (W56/100, 104, 108, 112, 116, 120, 124,
128, 132, 136, 140, 144 ch)
Using a 5.2/5.3-GHz-band wireless LAN outdoors is prohibited
by law (this does not apply to communication with access
points/relay stations of high-output data communications
systems operating in the 5.2 GHz band).
Frequency Bands (6 GHz Band)
Within the 6 GHz frequency band, handset can use the 5925
to 6425 MHz band.
Handset's 6 GHz device power class is LPI (Low Power Indoor).
Using a 6-GHz-band (LPI) wireless LAN outdoors is prohibited
by law.

Cautions for General Use
The frequency band used by handset Bluetooth
(wireless LAN) functions is also used for operation by
household appliances (microwave ovens) and industrial/
scientific/medical equipment as well as by in-place radio
stations (requiring a license) and specific low-power radio
stations (not requiring a license) for mobile identification
as used in production lines, and by amateur radio stations
(requiring a license).
1. Before using Bluetooth
/Wi-Fi (wireless LAN), check that
®
no in-place radio stations for mobile identification, specific
low-power radio stations, or amateur radio stations are in
operation nearby.
2. If use of handset Bluetooth
interference with regard to an in-place radio stations for
mobile identification, immediately change the usage frequency,
or discontinue use and take measures to avoid interference
(putting a partition in place, etc.).
3. If handset is otherwise a cause of interference with regard
to specific low-power radio stations for mobile identification
or amateur radio stations and assistance is required, contact
Customer
Service.
Bluetooth
and Wi-Fi (Wireless LAN)-
®
Compatible Devices and Interference
Bluetooth
and Wi-Fi (IEEE 802.11 b/g/n/ax) use the same
®
frequency band (2.4 GHz). Using Bluetooth
(wireless LAN) access point or device may cause interference
and affect communication speed connection. If this occurs,
either distance handset and the device connecting by
Bluetooth
, or turn off the Wi-Fi (wireless LAN) device so as
®
to prevent interference.
Wi-Fi (Wireless LAN)
Do not use where there are devices with magnetic fields
(electrical products, AV/OA equipment, etc.) or where there is
an electromagnetic field.
・The effect of magnetism and electrical noise may cause
increased noise and prevent communication. Handset may in
particular be affected by a microwave oven.
・Proximity to a TV, radio, etc. can block reception and cause
a snowy TV screen.
・If multiple Wi-Fi (wireless LAN) access points using the
same channel are in proximity, handset may not detect
access points correctly.
