services are unavailable.
・Wi-Fi router accommodates software updates. Use the
latest software.
・Wi-Fi router employs radio waves. Signals may be disrupted
even within service areas if you are indoors, underground,
inside a tunnel or inside a vehicle. If you move to a location
with poor signal strength, a call may be suddenly cut off.
・When using Wi-Fi router in public places, take care not
to annoy other people around you. Use of Wi-Fi router is
prohibited in some public places such as in theaters or on
buses and trains.
・Wi-Fi router is a wireless station under Japanese Radio
Law. You may be requested to submit your Wi-Fi router for
inspection based on this law.
・Data stored on Wi-Fi router may be corrupted or lost on the
following occasions:
・Wi-Fi router is used improperly.
・Wi-Fi router is exposed to static electricity or electrical
noise.

・If using a WLAN device abroad, configuration changes based
on the law of the country are required. Confirm user manual
for the settings.
・Connection speed may drop or connections may not be
established depending on line traffic or connection
environments.
・Do not use Wi-Fi router in or near places where explosives
are handled. Wi-Fi router use may lead to an explosion, or
affect explosion devices.
・Wi-Fi router USIM Card cannot be used with some mobile
devices (including previously sold SoftBank models).
・Since Wi-Fi router and AC Charger might get hot while
charging or while being used for prolonged periods, contact
with the skin for a long time may result in low-temperature
burns. Be careful in handling.

Wi-Fi (Wireless LAN)
・Precautions
Do not use Wi-Fi (WLAN) near devices emitting
electromagnetic waves such as electrical appliances or AV/
OA equipment.
・Electromagnetic noise (e.g. from microwave ovens) may
impair or disable communications.
・Using Wi-Fi (WLAN) near a TV or radio, etc. may cause
interference/impair signal reception.
・If multiple Wi-Fi (WLAN) access points in close vicinity are
using the same channel, search may fail.
・Wireless Frequencies & Modulations
Wi-Fi frequency that Wi-Fi router uses is as follows.
Items Descriptions
2.4 2400 MHz range
DS/OF DSSS or OFDM modulation
4 Maximum interference range of 40 m
Utilizes 2400 - 2483.5 MHz band with
mobile device bandwidth differentiation
1 Available channels vary depending on the country.
2 For use aboard aircraft, contact the airline beforehand.
3 If using WLAN abroad, confirm usable frequency, laws and
regulations in that country.
・2.4 GHz Device Cautions
Wi-Fi (WLAN) device operating frequency band is used
by industrial, scientific, consumer and medical equipment
including microwave ovens, premises radio stations for
identifying mobile units used in manufacturing lines (radio
stations requiring a license), specified low power radio
stations (radio stations requiring no license) and amateur
radio stations (radio stations requiring a license).
1. 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.
2. If the device causes harmful radio interference to
premises radio stations for identifying mobile units,
immediately change the frequency band or stop use, and
move to another location to avoid crosstalk (e.g. wall
partitions, etc.).
・WLAN Usage Security Precautions
Using Wi-Fi router without setting security increases risk
of data interception. Wi-Fi router security is set by default.
SoftBank recommends changing default security settings
to enhance data safety. For more information on security
settings, see this guide or Wi-Fi device guide.
・Beware that due to Wi-Fi (WLAN) specifications, security
settings can still be compromised by special means.
・For assistance with security settings, contact Customer
Service.
・SoftBank cannot be held liable for WLAN security issues.
