LEGAL INFORMATION
In order to provide you with better access to this important information, we've made the materials
accessible from the phone's Settings menu. Review these materials prior to using your mobile device. To
access the materials on your mobile device, swipe up from the home screen, and tap Settings > About
phone > Legal information, and select a topic.
REGULATORY INFORMATION (E-LABEL)
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.
FCC COMPLIANCE
Any changes or modifications not expressly approved by the party responsible for compliance of this
device voids the user's authority to operate this device.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) This device may not cause harmful interference
(2) This device must accept any interference received, including interference that may cause undesired
operation.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant
to Part 15 of the FCC Rules. 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.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
HEARING AID COMPATIBILITY (HAC)
The FCC has established requirements for digital wireless mobile devices to be compatible with hearing
aids and other assistive hearing devices.
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.
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.
The ratings are not guarantees. Results will vary depending on the user’s 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).
This device complies with FCC radiation exposure limits set forth for an uncontrolled
environment. To ensure compliance with the RF exposure guidelines, the device must be
used at least 15mm from your body.
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, then tap
Settings > About phone > Legal information > RF Exposure.
