Wi-Fi
・Frequencies
Handset Wi-Fi function uses 2.402 GHz – 2.480 GHz
frequencies in the 2.4 GHz band.
2.4DS4/OF4: Uses 2.4 GHz band and DSSS/OFDM modulation
with a maximum interference range of 40 m.
: Utilizes 2.402 GHz – 2.480 GHz band with
mobile device bandwidth differentiation.
・Wi-Fi Cautions
・Handset wireless function is certified as conforming to
Japanese domestic and FCC regulations. Use is restricted
in some countries/regions. Confirm local laws before use
abroad.
・The 2.4 GHz band used by handset Wi-Fi function is
shared by other devices. Handset Wi-Fi function tries to
minimize effects of other devices using the same bandwidth,
but connection speed and distance may be reduced or
function may be disconnected.
・Connection speed and distance vary depending on distance
between connected devices, obstacles, and Wi-Fi devices.
・Before Using Wi-Fi
Wi-Fi operating frequency band is used by industrial,
scientific, consumer and medical equipment including
microwave ovens, other similar radio stations, 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 (hereafter, "other
radio stations").
1. Before handset use, be sure "other radio stations" are not
in use nearby.
2. If handset radio waves interfere with "other radio
stations", promptly move or power off.
3. For further information, visit a SoftBank Shop or contact
Customer Service.
・All handset operations when connected with a Wi-Fi-
compatible device are not verified and therefore not
guaranteed.
・Handset supports the Wi-Fi-standard security function
for secure radio communication. However, be careful when
using Wi-Fi, as security may be insufficient depending on
conditions of usage or settings.
・SoftBank accepts no liability for data/information leaks
during communication using Wi-Fi.
Water & Dust & Shock Resistance
Handset has IPX5-equivalent and IPX8-equivalent water
resistance as well as IP5X-equivalent dust resistance with
Back Cover completely attached. Handset is also provided with
shock resistance complying with military standards (SoftBank
testing).
Specifically, handset can be used in rain (less than 20 mm
per hour) without an umbrella. Handset can also be used in
bathrooms, kitchens, at poolside, and other places with water.
* For details, see "In Various Environments."
However, failure to observe precautions given here may allow
water, sand, foreign particles, etc. to enter handset and
may cause overheating, ignition, electric shock, scratches,
malfunction, etc. For safe handset use, first read precautions
here.
IPX5 equivalent
Handset continues to function as a phone after being sprayed
from all directions with 12.5 L of water per minute from
a 6.3 mm diameter nozzle for at least 3 minutes, from a
distance of approximately 3 m.
IPX8 equivalent
Handset continues to function as a phone without water
intrusion after being slowly immersed in still tap water of
room temperature to a depth of 1.5 m, and left there for
approximately 30 minutes before being removed again.
IP5X equivalent
Handset will maintain a certain level of functionality and
safety even after particulates in dustproof testing (dia. 75
μm or less) have entered handset.
Compliance with Military Standards
Although drop testing in compliance with MIL-STD-810G
Method 516.7：Shock-Procedure IV as stipulated by the US
Department of Defense (product dropped in 26 directions
onto plywood (lauan) from a height of 1.22 m), this is not a
guarantee with regard to all types of shock.
* As handset is designed with shock resistance in everyday
usage, handset may break if subjected to excessive impact
such as being thrown against something. Dropping may
produce scratches, etc. even if handset performance is
unaffected.
Before Use
・Attach Back Cover firmly to prevent water intrusion.
Confirm that Covers are completely secure so that there are
no gaps.
・Particles (lint, hair, sand, etc.) lodged between joining
surfaces may allow water intrusion.
・DO not attach/remove Back Cover if hands/handset is wet.
・Do not place handset directly on beach sand, etc. Exposing
Mic/Earpiece/Speaker/etc. to sand may reduce volume.
・Do not use submersed (including key operation).
・Do not expose to or immerse in liquid other than room
temperature fresh water or tap water (soap/detergent/bath
salt water, hot spring water, hot water, muddy water, sea
water, pool water, alcohol, etc.).
