Safety Precautions
944SH complies with IPX5 (former JIS
protection level 5)1and IPX7 (former JIS
protection level 7)2water protection standards
as well as IP5X (JIS protection level 5)3dust
protection standard, with Port Cover and
Battery Cover closed firmly.
1
IPX5 compliant means that a handset continues to
function as a phone after being subjected to a
water jet (approximately 12.5 liters/min.) discharged
from a nozzle (inner diameter: 6.3 mm), from all
directions (approximately 3 m from handset) for at
least 3 minutes.
2IPX7 compliant means that a handset continues
to function as a phone after being gently
submerged to the depth of 1 m in still tap water at
room temperature, left there for approximately
30 minutes, then removed from it.
3IP5X compliant means that a handset continues to
function as a phone and its safety is maintained
after being agitated in a device containing dust of
75 µm or smaller in diameter for 8hours, then
removed from the device.
.Water/dust resistance may be affected under
some circumstances. Malfunction resulting
from misuse is not covered by the warranty.
.944SH is compliant with IPX5, IPX7 and IP5X
water/dust protection standards. However,
ingress of dirt, sand, mud, metal powder,
food, beverage, etc. may cause malfunction.
.Do not subject handset to soap, detergent, bath
powder/oil, sea/pool/spa water, hot water, etc.
.Wash off sea/pool water, beverage, dirt, sand,
mud, etc. immediately; residue may cause
malfunction if allowed to dry.
.Wash off sand, dirt, etc. completely before use;
any residue may damage handset causing
malfunction.
.Do not soak handset in bath or pool; never use it
in water (including opening/closing of handset
and pressing keys).
.Handset is not resistant to water pressure.
Avoid high-pressure water/shower (over 6 liters/
min.) or water immersion.
.Do not expose handset to extreme humidity for
long periods; avoid prolonged use in bath/
shower rooms.
.Do not use in saunas. Avoid hot air from dryers,
etc.
.Use handset within 5oC - 35oC (up to 40oC for
brief periods in bath/shower rooms, etc.) and
35% - 90% humidity.
.Avoid extreme temperatures (e.g., near stoves,
inside refrigerators, etc.).
.Volume may be low when Microphone/Earpiece/
Speaker is wet; dry handset before use.
.Battery, Desktop Holder and optional
accessories are not waterproofed or
dustproofed.
.Do not subject handset to strong shocks or
impacts; do not poke Microphone, Earpiece,
Speaker, etc. with a cotton swab or sharp
object; water/dust resistance may be affected.
.Avoid placing handset directly on sand. Sand
may penetrate Earpiece, Speaker, etc., resulting
in low volume.
.Sand, etc. trapped in the hinge may cause
excessive friction or noise when opening/closing
handset.
.Touch Panel (Sub Display) may not respond
properly if wet or touched with wet fingers.
.Do not move handset directly from a cold place
to a warm humid place; condensation may
occur. Should this happen, dry handset
naturally at room temperature.
.944SH does not float on water.
.Keep handset out of heavy rain.
.Do not let liquid-exposed handset remain wet;
exposure to cold may freeze liquid causing
malfunction.
.Damaged Battery/Port Cover affects water/dust
resistance; contact a SoftBank Shop.
Water & Dust Resistance
944SH Water & Dust Resistance Important Notes
.Close Battery Cover and Port Cover firmly.
Debris (hair, sand, fibers, etc.) trapped between
cover and base may expose handset to liquid/
dust.
.If Battery/Port Cover is left open liquid exposure
may cause handset malfunction/electric shock.
Power handset off, then remove battery.
.If handset is wet, wipe it with dry cloth.
.Do not open/close Battery/Port Cover with wet
hands or while handset is wet.
.Handset is resistant to fresh/tap water at normal
temperature (5oC - 35oC) only.
