Care and maintenance Your phone is a product of superior design and craftsmanship and should be treated with care. The suggestions below will help you to fulfill any warranty obligations and allow you to enjoy this product for many years. When using your phone, battery, charger, or any accessory: • Keep it and all its parts and accessories out of the reach of small children. • Keep it dry. Precipitation, humidity, and liquids contain minerals that will corrode electronic circuits. • Do not use or store it in dusty, dirty areas as its moving parts can be damaged. • Do not store it in hot areas. High temperatures can shorten the life of electronic devices, damage batteries, and warp or melt certain plastics. • Do not store it in cold areas. When the phone warms up to its normal operating temperature, moisture can form inside the phone, which could damage the phone's electronic circuit boards. • Do not attempt to open it. Non-expert handling of the device could damage it. • Do not drop, knock or shake it. Rough handling can break internal circuit boards. • Do not use harsh chemicals, cleaning solvents, or strong detergents to clean it. Wipe it with a soft cloth that has been slightly dampened in a mild soap-and-water solution. • Do not paint it. Paint can clog the device's moving parts and prevent proper operation. 18 If the phone, battery, charger, or any accessory is not working properly, take it to your nearest qualified service facility. The personnel there will assist you, and if necessary, arrange for service. [ 126 ]
