• Do not touch the battery terminals. Batteries can cause damage, injury or burns if a conductive material touches exposed terminals. When the battery is detached from the phone, use a cover made of nonconductive material for keeping and carrying the battery safely. • Recommended temperature for using and storing batteries is approximately 20°C. • The batteries' performance is limited in low temperatures, particularly below 0°C and the phone may not work temporarily regardless of the amount of remaining battery power. • Exposing the phone to extreme temperatures will shorten battery life. • The battery can be charged and discharged hundreds of times but it will eventually wear out. When the operating time (talk-time and standby time) is noticeably shorter than normal, it is time to buy a new battery. CAUTION RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE, DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS See "Battery Disposal" on page 12. Aerial Care • Do not cover the hinge area of the phone (p. 8 and 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. • Whilst 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. 120 Safety Precautions and Conditions of Use
