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
www.sonymobile.com/global-en/
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.
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 metres or less, for example, in a fresh water
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 ability 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 in contact with salt water. For example, if you’re at the beach, remember to
keep your device away from the sea water. Also, never expose the device to any
liquid chemicals. For example, if you’re washing dishes by hand using liquid
detergent, avoid bringing your device in contact with the detergent. After exposure to
non-fresh water, rinse your device using fresh water.
Normal wear and tear along with damage to your device can reduce its ability to
resist dust or moisture. After using the device in water, dry off the areas around all
covers, including the covers for the micro USB port, the SIM card slot and the
memory card slot.
If the speaker or microphone get wet, their function may be impacted until the water
has completely dried. Please note that the drying time can be up to three hours
depending on the environment. During this time, you can, however, use other
features in the device that do not utilise the speaker or microphone. All compatible
