cover, and earphone microphone terminal
cover are securely closed.
*1 IPX5 equivalent means that the prod-
uct 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
litres per minute from any direction.
*2 IPX8 equivalent means that the prod-
uct will maintain its operability as a
phone with no water getting inside the
main unit, even if it is gently sub-
merged in a tank of still tap water at
room temperature to a depth of 1.5
meters for about 30 minutes.
*3 IP6X equivalent means that the prod-
uct will not allow the intrusion of grit or
