Radio Frequency Interference Radio-frequency emissions from electronic equipment can negatively affect the operation of other electronic equipment, causing them to malfunction. Although iPhone is designed, tested, and manufactured to comply with regulations governing radio frequency emission in countries such as the United States, Canada, the European Union, and Japan, the wireless transmitters and electrical circuits in iPhone may cause interference in other electronic equipment. Therefore, please take the following precautions: Aircraft Use of iPhone may be prohibited while traveling in aircraft. For more information about using Airplane Mode to turn off the iPhone wireless transmitters, see the iPhone User Guide. Vehicles Radio frequency emissions from iPhone may affect electronic systems in motor vehicles. Check with the manufacturer or its representative regarding your vehicle. Pacemakers The Health Industry Manufacturers Association recommends that a minimum separation of 15 cm (6 inches) be maintained between a handheld wireless phone and a pacemaker to avoid potential interference with the pacemaker. Persons with pacemakers: ÂÂ Should always keep iPhone more than 15 cm (6 inches) from the pacemaker when the phone is turned on ÂÂ Should not carry iPhone in a breast pocket ÂÂ Should use the ear opposite the pacemaker to minimize the potential for interference If you have any reason to suspect that interference is taking place, turn iPhone off immediately. Hearing Aid Compatibility (HAC) iPhone has been tested and rated under the American National Standard Institute (ANSI) C63.19-2007 hearing aid compatibility standard. The ANSI standard measures radio frequency interference for acoustic coupling ("M" rating) and inductive coupling with hearing aids operating in telecoil mode ("T" rating). Phones must be rated M3 or greater and T3 or greater to be hearing aid compatible under FCC rules. iPhone 4 CDMA model is hearing aid compatible under FCC rules. iPhone 4 GSM model is hearing aid compatible under FCC rules when Hearing Aid Mode is activated. To activate Hearing Aid Mode on iPhone 4, go to Settings > General > Accessibility. Activating Hearing Aid Mode may reduce 2G cellular coverage. For more information, see the "Hearing Aid Compatibility" section of the iPhone User Guide.
