Water/Dust/Shock Resistance
Handset has IPX5-equivalent and IPX8-equivalent water
resistance as well as IP5X-equivalent dust resistance with
Back Cover and External Device Port 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
・Close External Device Port Cover securely and attach Back
Cover firmly to prevent water intrusion. Confirm that
Covers are completely secure so that there are no gaps.
・Particles (hair, sand, etc.) lodged between joining surfaces
may allow water intrusion.
・DO NOT open/close External Device Port Cover or 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.).
