Precautions
Waterproofness/Dustproofness
The terminal provides waterproofness of IPX5
*1
, IPX8
*2
and
dustproofness of IP6X
*3
with firmly attaching the docomo nanoUIM
card/microSD memory card slot.
*1 IPX5 means that a phone keeps functioning after applying a jet flow
of 12.5 L/min. from every direction from a distance of approximately 3
m for at least 3 minutes using water nozzle in 6.3 mm inner diameter.
*2 IPX8 means that a communication device keeps functioning after a
phone is slowly submerged to depth of 1.5 m in static tap water at
ordinary temperatures, left there for 30 minutes and then taken out.
*3 IP6X means a protection degree that dust cannot come in to that do
inside of phone and a phone maintains safety after it is placed in a
phone with dust in diameter 75 μ m or less for 8 hours, agitated and

What you can do with waterproofness of the terminal
■ You can talk without an umbrella in the rain (for rainfall of 20 mm
or less per hour).
■ The terminal can be washed with tap water at ordinary
temperatures.
• Do not apply water flow stronger than allowed (P.18).
• Do not use brush, sponge, soap, detergent, etc.
• If mud or soil is adhered to the terminal, eliminate the dirt first by
shaking several times in tap water of wash-basin and then wash the
terminal with running water.
• Drain water in the specified steps (P.19) after washing.
• Do not wash rubbing strongly.
To ensure waterproofness/dustproofness
■ To avoid water/dust ingress, be sure to observe the following
points.
• Do not apply liquids except for tap water at ordinary temperatures.
• Do not poke mouthpiece/microphone, receiver, speaker, USB Type-C
connection jack, headphone connection jack with a sharp object.
• Do not let the terminal fall. It may become scratched causing the
waterproof/dustproof performance to degrade.
• Make sure that the docomo nanoUIM card/microSD card tray is tightly
closed. Even a fine debris (a piece of hair, a grain of sand, fine fiber,
etc.) between contact surfaces may allow water or dust to enter the
interior of the terminal.
To keep the terminal waterproofness/dustproofness, replacement
of parts is required every 2 years regardless of whether the terminal
appears normal or abnormal. DOCOMO takes the terminal to replace the
parts as a chargeable service. Bring the terminal to a sales outlet such
as a DOCOMO-specified repair office.
