Notes on Waterproof, Dustproof 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 jack cover, earphone
jack cover and battery cover are securely attached. Furthermore,
the product has a shock-resistant property (compliant with MIL
standards
*4
) to withstand hard day-to-day use. (Based on in-house
testing.)
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 intrusion of water, sand or other foreign material,
resulting in overheating, fire, 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
meters 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 μm or less and shaken for 8 hours.
*
4
Tests were performed under independent standards compliant to MIL-
STD-810G Method 516.6-Procedure IV established by the United States
Department of Defense, where the product is dropped closed from 1.22
m onto plywood (lauan wood) in 26 directions.
*
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 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
jack cover and earphone jack cover are
firmly closed, and the battery cover is
securely attached.
•
Waterproof, dustproof and shock-
resistant properties are only effective
when the covers are securely closed.
•
Just a small particle (a hair, etc.) on
the seals can cause water or dust to
enter inside.
•
Do not open/close the external connection jack cover,
earphone jack cover or battery cover if the main unit or your
hands are wet.
•
For how to close the battery cover, refer to “Attaching/
Removing the Battery Pack” (

P.32).
•
For how to close the external connection jack cover and
earphone jack cover, refer to “Opening/Closing the External
Connection Jack Cover or Earphone Jack Cover” (
