These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Home A.C./Travel chargers will operate within the temperature range of: 0C (32F) to 45C (113F). Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. The chargers designed for your mobile device meet with the standard for safety of information technology equipment and office equipment use. Due to different applicable electrical specifications, a charger you purchased in one jurisdiction may not work in another jurisdiction. HEARING AID COMPATIBILITY (HAC) Consult the dealer or an experienced radio/TV technician for help. REGULATORY INFORMATION (E-LABEL) The FCC has established requirements for digital wireless mobile devices to be compatible with hearing aids and other assistive hearing devices. Your mobile device uses an electronic label (e-label) that provides regulatory information about your device. To view the regulatory information (such as FCC ID) for this device, on the device, swipe up from the home screen, then tap Settings > About phone > Regulatory & safety. When wireless devices are used near hearing devices (such as hearing aids and cochlear implants), users may detect a buzzing, humming, or whining noise. Some hearing devices are more immune than others to this interference, and wireless devices also vary in the amount of interference that they generate. 43 44 The wireless telephone industry has developed ratings to assist hearing device users in finding wireless devices that may be compatible with their hearing devices. Not all wireless devices have been rated. Wireless devices that are rated will have the rating displayed on the box together with other relevant approval markings. LICENSES The ratings are not guarantees. Results will vary depending on the users hearing device and hearing loss. If your hearing device is vulnerable to interference, you may not be able to use a rated wireless device successfully. Consulting with your hearing health professional and testing the wireless device with your hearing device is the best way to evaluate it for your personal needs. This smartphone has been tested and rated for use with hearing aids for some of the wireless technologies that the smartphone uses. However, other wireless technologies may be used in this smartphone that have not been tested for use with hearing aids. It is important to try the different features of your smartphone thoroughly and in different locations to determine if you hear any interfering noise when using this smartphone with your hearing aid or cochlear implant. Consult your wireless service provider about its return and exchange policies, and for information about hearing aid compatibility. Your device includes a radio transmitter and receiver. It is designed and manufactured not to exceed the exposure limits for Radio Frequency (RF) set by the Federal Communications Commission (FCC). The RF exposure limits set by the FCC for wireless mobile devices utilize a unit of measurement referred to as Specific Absorption Rate (SAR), which is a measure of the amount of RF energy absorbed by the body when using a mobile device. The FCC requires mobile device manufacturers to ensure that their mobile devices comply with these objective limits for safe exposure. The FCC SAR limit incorporates a substantial margin of safety to give additional protection to the public and to account for any variations in measurements. The FCC limit for public exposure from cellular telephones is a SAR level of 16 watts per kilogram (1.6 W/kg). SAR information for this device can be found on the FCC website at www.fcc.gov/oet/ea/. Follow the instructions on the website to use the FCC ID for this device to find SAR values for the device. To view additional SAR information on your phone, swipe up from the Home screen > Settings >
