Maintaining Water/Dust Resistance
To prevent water or dust intrusion, be sure to observe the
following.
・To install/remove SIM Card or SD Card, push tip of SIM
Removal Pin in hole in Slot Cap, and then pull out ejected
Slot Cap straight without bending.
* Do not push down on ejected Slot Cap down. May damage
Slot Cap.
・After use, insert Slot Cap straight without bending in
direction shown, and press firmly where circled ○. Make
sure there is no gap between handset and Slot Cap.
・Close firmly. Anything tiny (a single hair, grain of sand,
minute fiber, etc.) trapped between seal and contacting
surface may allow ingress of water/dust.
・Do not poke Stereo Earphones Port, USB Type-C Port, Mic/
Recorder Mic, Earpiece, Speaker, Sub-Mic, Slot Cap, etc with
anything pointed.
・Do not drop. Scratches, etc. can deteriorate water/dust
resistance.
・Slot Cap rubber seal is crucial for continued water and dust
resistance. Do not remove or scratch rubber seal. Do not
allow dirt to get on seal.
・To maintain water and dust resistance, it is recommended
to replace parts every 2 years regardless of their condition.
Submit handset for parts replacement at a fee. Contact a
SoftBank Shop or Customer Service.
