and shock-resistant properties
This product has a waterproof property equivalent to IPX5
*1
and IPX8
*2
, as well as a dustproof property equivalent to
IP5X
*3
on the condition that the external connection terminal
cover and the card slot cover are securely attached. This
product has a shock-resistant property conforming to the
MIL standard
*4
(based on in-house testing).
Specifically, you can make calls holding the product with
wet hands in the rain (less than 20 mm per hour) without an
umbrella, as well as use the product in a place with water
such as a bathroom or kitchen.
Before using the product, thoroughly read "Important items
to remember before use" and "Tips for comfortable use" to
ensure correct use. Failure to follow the contents described
in these sections may cause the intrusion of water, sand
or other foreign material, resulting in overheating, ignition,
electric shock, injury or a fault.
*1 IPX5 equivalent means that the product will maintain its operability as a
phone even if it is sprayed with water from a 6.3 mm diameter nozzle at
a distance of about 3 meters for more than 3 minutes at a rate of about
12.5 liters per minute from any direction.
*2 IPX8 equivalent means that the product will maintain its operability as
a phone with no water getting inside the main unit even if it is gently
submerged in a tank of still tap water at room temperature to a depth of
1.5 meter for about 30 minutes.
*3 IP5X equivalent means that the product will securely maintain its
operability as a phone even after it has been placed in an apparatus with
grit and dust of diameters of 75
μ
m or less and shaken for 8 hours.
*4 MIL standard conformity: Drop testing (in which the product is dropped
in 26 directions from a height of 1.22 m) was conducted in accordance
with MIL-STD-810G Method 516.6-Shock defined by the U.S. Department
of Defense. Shock-resistant property of this product is based on the
assumption that it is used in everyday life. Therefore, the product might
break if it receives an excessive impact such as being thrown or dropped
forcibly. Note also that the product gets scratches, etc. by falling impact
even though its functionality of the main unit remains intact.
Since operation of the product on each usage scene
was confirmed based on the above assumption, proper
operation of the product in every possible condition during
actual use is not guaranteed. Malfunctions determined to
be caused by mishandling by the customer are not covered
by the warranty.
Important items to remember before use
Make sure that the external
connection terminal cover
and the card
slot cover
are
firmly closed.
• Waterproofness is only
effective when the covers
are securely closed.
• Just a small particle (a hair,
a grain of sand, etc.) on the
seals can cause water leak.
