Sharp SHV43 Notes On Usage page 25

● While writing/reading data to/from a microSD memory card, do not subject
the product to vibration or impact or turn off the power. Doing so might
cause loss of data or a fault.
● Note that covering the light sensor with fingers or stickers will prevent the
sensor from responding to ambient brightness and operating properly.
● Do not put a sticker, etc. on the proximity sensor. Doing so may cause the
sensor to malfunction and make the display always turned off while making
a call or during a call.
● Note that covering earpiece (receiver)/speaker, mouthpiece (microphone),
or air vent (in mobile light) with stickers, fingers, etc. will affect
performance.
● If you hold the phone to talk with hair covering your ear, the proximity
sensor may malfunction. This may cause the display to remain on, allowing
the call to be disrupted if the display is accidentally touched.
● If the display gets damaged, immediately stop use and contact an au shop
or Repair and Delivery Service Center. Keeping using it may cause injury.
● Putting a sticker, etc. on the display or a key may cause malfunction or
shortened usage time. Also, doing so may damage the product.
● If you put magnetized objects close to the product, the speaker section
sometimes emits sounds. This is not a fault.
● Note that if you forcefully pull the au IC Card/microSD memory card tray or
apply excessive force on it, it may be damaged.
● Bright places such as under the direct sunlight sometimes make it hard to
see the display. This is not a fault.
● Use the product with the au IC Card/microSD memory card tray closed. If
the tray is open, dirt or water may get inside causing a fault.
● Do not allow liquids, metal objects, and other foreign matter to get inside
the au IC Card/microSD memory card tray slot of the product. Doing so
might cause a fault.
● Do not subject to strong impact to the product such as dropping, throwing
or stepping it. Doing so might cause a fault.
● Do not put the product directly on sand at a beach, etc. Sand or other small
particles might get inside the earpiece/speaker, mouthpiece, or earphone/
microphone jack causing the volume to drop. If sand gets inside the
product, it might cause overheating or a fault.
