Turning Off Your Phone in Dangerous Areas To avoid interfering with blasting operations, turn your phone off when in a blasting area or in other areas with signs indicating two-way radios should be turned off. Construction crews often use remote-control RF devices to set off explosives. Turn your phone off when you're in any area that has a potentially explosive atmosphere. Although it's rare, your phone and accessories could generate sparks. Sparks can cause an explosion or fire, resulting in bodily injury or even death. These areas are often, but not always, clearly marked. They include: Ⅲ Fueling areas such as gas stations. Ⅲ Below deck on boats. Ⅲ Fuel or chemical transfer or storage facilities. Ⅲ Areas where the air contains chemicals or particles such as grain, dust, or metal powders. Ⅲ Any other area where you would normally be advised to turn off your vehicle's engine. Note: Never transport or store flammable gas, flammable liquids, or explosives in the compartment of your vehicle that contains your phone or accessories. Restricting Children's Access to Your Phone Your phone is not a toy. Do not allow children to play with it as they could hurt themselves and others, damage the phone or make calls that increase your Sprint invoice. Please Note the Following Information When Using Your Handset 1. WARNING REGARDING DISPLAY Ⅲ The display on your handset is made of glass or acrylic and could break if your handset is dropped or if it receives significant impact. Do not use if screen is broken or cracked as this could cause injury to you. 2. WARRANTY DISCLAIMER: PROPER USE OF A TOUCH SCREEN HANDSET Ⅲ If your handset has a touchscreen display, please note that a touchscreen responds best to a light touch from the pad of your finger or a non-metallic stylus. Using excessive force or a metallic object when pressing on the touchscreen may damage the tempered glass surface and void the warranty. For more information, please refer to the "Manufacturer's Warranty" on page 197. Using Your Phone With a Hearing Aid Device A number of Sprint phones have been tested for hearing aid device compatibility. When some wireless phones are used with certain hearing devices (including hearing aids and cochlear implants), users may detect a noise which can interfere with the effectiveness of the hearing device. 190 4A.
