• Do not keep the product next to credit cards or transport tickets; the speaker magnet could corrupt the information on the magnetic strip. • Do not keep the product in an area prone to dust and dirt since this can impair the operation of the moving parts of your product. • When you need to clean the screen, switch off the product and use a commercial glass screen cleaner sprayed on a soft cloth. Avoid spraying the screen directly. ·Over time, you may notice rainbow-like rings forming on the screen. These rings are only cosmetic and will not impede the functioning of your product. • Keep the product away from strong magnetic fields (e.g. loudspeakers) and sources of static electricity. • If you will not be using the product for a while, store it in a place that is dry, free from damp, dust and extreme heat and cold. As a matter of precaution, make a back-up of your files before you store your product. ANTENNA CARE To avoid impaired performance, please ensure that your smartphone's antenna is not bent or damaged. Do not remove the antenna yourself. If your smartphone's antenna is damaged, please take it to a Sony Ericsson Service Partner. Only use an antenna that has been specifically designed by Ericsson for your smartphone. Use of unauthorised antennas, modifications, or attachments could damage the smartphone and may violate the appropriate regulations, causing loss of performance and radio frequency (RF) energy above the recommended limits. 230 Important Information
