Aerial Care • Do not cover the top of the phone (p. 10, No. 19) with your hand when in use as this may interfere with the performance of the built-in aerial. Call quality may deteriorate leading to shortened talk-time and standby time because the mobile phone has to operate on a higher power level than is necessary. • Use only the aerial supplied or one approved by Sharp for your mobile phone. Using unauthorised or modified aerials may damage the mobile phone. Moreover, since the mobile phone may violate the appropriate regulations, it may lose performance or exceed the limitation of SAR levels. • To avoid impaired performance, do not damage the aerial of the mobile phone. • While talking directly to the microphone, please hold the mobile phone so that the aerial is upwards over your shoulder. • To avoid interfering with blasting operations, please turn off the mobile phone in a blasting area or in a place where a "turn off two-way radio" sign is posted. Camera Operation • Learn picture quality, file formats, etc. beforehand. The taken pictures can be saved in JPEG format. • Be careful not to move your hand while taking pictures. If the phone moves while taking a picture, the picture can become blurred. When taking a picture, hold the phone firmly to prevent it from moving, or use the delay timer. • Clean the lens cover before taking a picture. Fingerprints, oils, etc. on the lens cover hinder clear focusing. Wipe them off with a soft cloth before taking a picture. Safety Precautions and Conditions of Use 149
