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.
1IPX5 protection standard compliant means that
this 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.
2
IPX7 protection standard compliant means that
this handset continues to function as a phone and
no water seeps inside after being gently lowered
into a tank filled with still tap water (at room
temperature) to the depth of 1 m, and immersed at
the bottom for approximately 30 minutes.
3IP5X protection standard compliant means that
ingress of dust (75 µm or smaller in diameter;
used in the dustproof test) will not affect
performance or safety of this handset.
.Water/dust resistance may be affected under
some circumstances. Malfunction resulting
from misuse is not covered by the warranty.
.841SH s 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,

may penetrate Earpiece, Speaker, etc., resulting
in low volume.
.Sand, etc. trapped in the hinge may cause
excessive friction or noise when opening/closing
