6If you are concerned about exposure to RF energy, you can limit your exposure by limiting the amount of time using iPod touch, since time is a factor in how much exposure a person receives, and by placing more distance between your body and iPod touch, since exposure level drops o?? dramatically with distance.Additional InformationFor more information from the US FCC about exposure to RF energy, see: www.fcc.gov/oet/rfsafetyFor information about the scientifi c research related to RF energy exposure, see the EMF Research Database maintained by the World Health Organization at: www.who.int/emfRadio Frequency InterferenceNearly every electronic device is subject to radio frequency interference from external sources if inadequately shielded or designed, or otherwise not confi gured to be compatible. As a result, iPod touch may cause interference with other devices. Read the following information and instructions to avoid interference problems: AircraftUse of iPod may be prohibited while traveling in aircraft. For information about how to turn o?? the iPod touch Wi-Fi transmitter, see the iPod touch Features Guide.VehiclesRF signals may a??ect installed or inadequately shielded electronic systems in motor vehicles. Check with the manufacturer or its representative regarding your vehicle.Electronic DevicesMost modern electronic equipment is shielded from RF signals. However, certain electronic equipment may not be shielded against the RF signals from iPod touch.PacemakersTo avoid potential interference with pacemakers, persons with pacemakers:Should always keep iPod touch more than six inches from their pacemaker when the device is turned onShould not carry iPod touch in a breast pocketIf you have any reason to suspect that interference is taking place, turn iPod touch o?? immediately.ÂÂ
