Safety Precautions

SoftBank 201M

Bluetooth

Function

・Connection with all Bluetooth

devices is not guaranteed.

・Handset complies with Bluetooth

security standards,

however, communication may be intercepted depending on
the environment/settings. Take care when using Bluetooth

・SoftBank Mobile is not responsible for data leaked via

Bluetooth

communication.

・Bluetooth

devices operate on the same frequency band

used by industrial or scientific machinery, consumer
electronics (like microwave ovens), medical equipment,
(licensed) premises radio stations used to identify mobile
units used in manufacturing lines, (unlicensed) specified low
power radios and (licensed) amateur radios.
1. Before using handset Bluetooth

functions, confirm that

premises radio stations, specified low power radios, and
amateur radios are not in use nearby.
2. If handset Bluetooth

function use interferes with

premises radio stations, immediately change frequency band,
or halt usage and take steps (set up a partition, etc.) to
prevent crosstalk.
3. If handset Bluetooth

function use interferes with

specified low power radios or amateur radios, contact
SoftBank Customer Support, General Information.

・Bluetooth

function uses frequencies in the 2.4 GHz band

ranging from 2,400 MHz to 2,483.5 MHz

・2.4FH1/XX8

Frequency Band: 2.4 GHz
Modulations: FH-SS, XX8
Estimated Range of Radio Frequency Interference: up to 10
m (FH-SS), 80 m (XX8)

: Utilizes 2,400 MHz to 2,483.5

MHz band with mobile device bandwidth differentiation

・When using Bluetooth

function in other countries, check

local regulations beforehand.

・Communication speed and connectable range vary by

conditions.

Wi-Fi (Wireless LAN)

・Connection with all Wi-Fi devices is not guaranteed.
・Handset complies with Wi-Fi security standards, however,

communication may be intercepted depending on the
environment/settings. Take care when using Wi-Fi.

・SoftBank Mobile is not responsible for data leaked via Wi-Fi

communication.

・Wi-Fi devices operate on the same frequency band used by

industrial or scientific machinery, consumer electronics
(like microwave ovens), medical equipment, (licensed)
premises radio stations used to identify mobile units used in
manufacturing lines, (unlicensed) specified low power radios
and (licensed) amateur radios.
1. Before using Wi-Fi, confirm that premises radio stations,
specified low power radios, and amateur radios are not in
use nearby.
2. If Wi-Fi use interferes with premises radio stations,
immediately change frequency band, or halt usage and take
steps (set up a partition, etc.) to prevent crosstalk.
3. If Wi-Fi use interferes with specified low power radios or
amateur radios, contact SoftBank Customer Support, General
Information.

・Wi-Fi uses radio waves to enable communication between

compatible devices within range. However, it is advisable for
the user to configure security settings to avoid risk of data
interception.

・Wi-Fi and Bluetooth

transmit on the same band. Enabling

handset Bluetooth

or using Bluetooth

devices near

handset may affect Wi-Fi transmission speed, availability
and clarity. Should interference occur, cancel handset
Bluetooth

or discontinue Bluetooth

device use.

・Wi-Fi uses frequencies in the 2.4 GHz and 5 GHz band

ranging from 2,400 MHz to 2,483.5 MHz
