Using Your Device in Wet and Dusty Conditions

To ensure the water resistance of your device, all covers, including the covers for the micro
USB port, 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
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 streams as well as against the effects of immersion for 30 minutes in
fresh (non-saline) water up to 1.5 meters deep.
You can use your device:
•
in dusty environments, for example, on a windy beach.
•
when your fingers are wet.
•
in some extreme weather conditions, for example, when it's snowing or raining.
•
in fresh (non-saline) water depths of 1.5 meters or less, for example, in a freshwater lake
or river.
•
in a chlorinated swimming pool.
Even if your device is resistant to dust and water, you should avoid exposing it
unnecessarily to environments with excessive dust, sand, and mud or to moist
environments with extreme high or low temperatures. The waterproof characteristic of
the micro USB port, the SIM card slot, the memory card slot, and the headset jack
cannot be guaranteed in all environments or conditions.
Never immerse your device in salt water or let the micro USB port or headset jack come
into contact with salt water. For example, if you're at the beach, remember to keep your
