What does it mean by waterproof in HTC Butterfly 2?
HTC Butterfly 2 has an IP Code of IPX7. The phone meets this standard under the
condition that the nano SIM and microSD covers are closed tightly.
That means:
§
The phone can continue to operate after it has been gently immersed in plain
tap water at room temperature, within 1 meter deep for no more than 30
minutes.
§
You can make and receive calls, even with wet hands and without an umbrella,
under moderate rain.
§
If the phone accidentally gets in contact with sea water, soapy water, or other
liquids, you can rinse it with a low flow of plain tap water.
HTC Butterfly 2 must not be exposed to non-fresh water, high water pressure, or sand
since these may cause overheating, electric shock, or damage to the phone. For usage
precautions and tips on care and maintenance, see
on page 31. Also make sure to read the
Safety guide that comes with your phone.
Important: Do's and don'ts
Before use
Make sure the nano SIM and microSD trays are inserted into the slots securely and
their covers are closed tightly. For instructions, see
§
Never attempt to insert or remove the nano SIM and microSD trays with gloves,
wet hands, or when the phone is wet.
§
Before closing the covers, wipe off every drop of water or dirt with a clean, dry
cloth.
§
When closing the covers, make sure that no hairs, fibers, or small particles are
caught between the covers and the slot openings to prevent water from
seeping through the gaps and entering the phone.
