dust resistance on the condition that Slot Cap is

securely attached. Also, handset comprises a shock-resistant
structure that has passed testing*

in accordance with US MIL

standards.
*1 IPX5 means that handset continues to function as a phone
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 handset continues to function as a phone
after being slowly submerged to depth of 1.5 m in still tap
water at room temperature, left there for 30 minutes and
then taken out (camera function cannot be used under water).
*3 IP6X indicates the level of protection and means that
handset is able to prevent intrusion of dust after being
agitated in a test device with 75 µm or smaller particles for 8
hours.
