Shared Precautions

・Close Card Slot Cap firmly after confirming rubber seal

is correct location. Also attach Back Cover firmly. Lodged
particles, no matter how small (lint, a single hair, grain of
sand, etc.), may allow water intrusion.

・Do not insert pointed object between Card Slot Cover and

handset. May scratch seal and allow water to enter.

・Do not open or close Card Slot Cover while wearing gloves.

Lodged particles (lint, hair, sand, etc.) from glove may allow
water intrusion.

・Check handset and hands for moisture, sand, grime, etc.

before opening or closing Card Slot Cap or attaching/
removing Back Cover. May enter handset or become lodged in
Cap or Cover, resulting in malfunction or water intrusion. If
moisture, sand, grime, etc. is visible, no matter how small,
first wipe handset and hands with lint-free clean, dry cloth
before handling.

・Do not leave handset wetted. Water may enter from gaps.

May also reduce volume. If wetted,

shake handset

, and

promptly remove as much water as possible with a lint-free
clean, dry cloth. In cold regions, handset may freeze and
cause malfunction.

・Handset is waterproof for only for fresh water/tap water.

Not waterproof for hot water, salt water, soap water,
chemicals, sweat, etc. If exposed to other types of moisture
or sand/mud/etc., promptly wash off with room temperature
tap water. Wash using hands (do not use brush) and hold
Back Cover/Card Slot Cap secured.
* Somewhat low water pressure (6 L or less per minute)

・Do not expose to strong water pressure (e.g., tap/shower

water that hurts) above rating (IPX5, IPX7) or immerse for
extended period.

・Do not wash in a washing machine, ultra-sonic washing

machine, etc.

・Do not subject to strong shock while submersed (e.g., drop

into basin, toilet, washing machine with water).

・Do not insert pointed objects in holes of Mic, Earpiece,

Speaker, 3.5mm Headphone Port, or External Device Port.

・Rubber seal on back of Card Slot Cap is vital to

waterproofing/dustproofing. Observe the following.
・Do not remove or scratch.
・Do not allow particles to adhere. Lodged particles (lint,
hair, sand, etc.) may allow water intrusion. Always remove.
・Remaining liquid other than fresh water or tap water (hot
water, salt water, detergent water, chemicals, sweat, etc.)
may degrade waterproofing.
・Be careful rubber seal is not pinched when securing Card
Slot Cap. Forcing Cap closed with rubber seal pinched can
scratch seal and may degrade waterproofing/dustproofing.
・Replace components for water, dust, and shock resistance
every two years regardless of appearance. Replacement
can be provided at cost while handset is retained. Visit a
SoftBank Shop or contact

SoftBank Customer Support

・Do not drop or otherwise subject handset to strong shock.

May degrade water, dust, or shock resistance.

・Handset is airtight to maintain water resistance (IPX7).

Pressing handset forcefully may produce sound around
Earpiece, but this is not a function or performance
abnormality.

・Handset will not float.
・Do not immerse in hot water, use in a sauna, or subject to

hot air from a hair dryer, etc.

・Use handset in temperatures between 5˚C – 35˚C and

humidity within 35% – 90% (limited use in temperatures
between 36˚C – 40˚C). Use in extremes beyond these ranges
may degrade water, dust, and shock resistance.

・Sudden temperature change results in condensation. Let

handset reach room temperature before moving from cold
to hot places (e.g., shower/bath) to prevent condensation.
Handset has no anti-condensation features.
* If condensation forms inside Display, leave at room
temperature until condensation dries.

・Do not run tap water directly on External Device Port.
・Do not leave handset with any water drops on it. May short-

circuit External Device Port.

・Do not leave any water on External Device Port.
・Before using External Device Port, check that there is no

foreign matter in Port.

・Handset fulfills performance requirements for assumed

usage. However, handset is not guaranteed for any and all
conditions of actual usage. Malfunction determined to be
due to mishandling is not covered under warranty.
