Using your device in wet and dusty conditions

To ensure the water resistance of your device, all covers, including the covers for the SIM card
slot and the memory card slot, must be firmly closed.
Your smart device is waterproof and dust resistant in compliance with the Ingress
Protection (IP) ratings IP65 and IP68, as explained in the table below. To view more
specific IP information about your device, go to
legal/testresults/ and click on the relevant device name.
These specific IP ratings mean that your device is dust resistant and is protected
against low pressure water stream as well as against the effects of immersion for 30
minutes in fresh (non-saline) water up to 1.5 metres deep.
You can use your device:
•
in dusty environments, for example, on a windy beach.
