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 When wireless devices are used near hearing devices (such  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.

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/.
