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
