What should I do if my device gets wet?
Avoid drying your device using external sources of heat (such as a hair dryer or microwave oven).
l
Avoid placing objects such as cotton swabs or tissue paper into the charging port or speaker holes.
Immediately dry all surfaces of your device, and then place it in a well-ventilated and dry area. Place
l
your device in front of a fan. Let the fan blow cold air against the charging port and speaker holes.
This may dry your device faster.
If your device has been immersed in water, or the microphone, receiver, or speaker is wet, the
l
sound may not be clear during calls. Dry your device by referring to the preceding operations.
If your device comes into contact with any liquids, do not charge the device or connect it to any
l
accessories. Use a piece of soft, lint-free cloth (such as microfiber cloth) to wipe your device dry
before using it. If you have further questions, bring your device and the proof of purchase to a
Huawei authorized service center for assistance.
The device has an oil repelling coating that prevents fingerprint smudges but may wear out over
l
time. Cleaning and corrosive products may further reduce the effectiveness of this coating and
scratch the device.
Despite the foregoing care tips, the device may still be susceptible to damage under certain
l
circumstances.
