While some wireless phones are used near some hearing devices (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 noise, and phones also vary in the amount of interference 

they generate.
The wireless telephone industry has developed a rating system for wireless 

phones, to assist hearing device users find phones that may be compatible

with their hearing devices.  Not all phones have been rated.   Phones that 

are rated have the rating on their box or a label located on the box. 
The ratings are not guarantees. Results will vary depending on the user’s 

hearing device and hearing loss.  If your hearing device happens to be 

vulnerable to interference, you may not be able to use a rated phone 

successfully.  Trying out the phone with your hearing device is the best way 

to evaluate it for your personal needs.
•  M-Ratings: Phones rated M3 or M4 meet FCC requirements and are

likely to generate less interference to hearing devices than phones that 

are not labeled. M4 is the better/higher of the two ratings.

•  T-Ratings: Phones rated T3 or T4 meet FCC requirements and are likely

to generate less interference to hearing devices than phones that are 

not labeled. T4 is the better/higher of the two ratings.

Hearing devices may also be rated.  Your hearing device manufacturer 

or hearing health professional may help you find this rating. Higher

ratings mean that the hearing device is relatively immune to interference 

noise. The hearing aid and wireless phone rating values are then added 

together. A sum of 5 is considered acceptable for normal use. A sum of 6 is

considered for best use. 

In the above example, if a hearing aid meets the M2 level rating and the

wireless phone meets the M3 level rating, the sum of the two values equal 

M5. This is synonymous for T ratings. This should provide the hearing aid

user with “normal usage” while using their hearing aid with the particular

wireless phone. “Normal usage” in this context is defined as a signal quality

that is acceptable for normal operation. 
The M mark is intended to be synonymous with the U mark. The T mark 

is intended to be synonymous with the UT mark. The M and T marks are 

recommended by the Alliance for Telecommunications Industries Solutions

(ATIS). The U and UT marks are referenced in Section 20.19 of the FCC

Rules. The HAC rating and measurement procedure are described in the

American National Standards Institute (ANSI) C63.19 standard.
To ensure that the Hearing Aid Compatibility rating for your phone

is maintained, secondary transmitters such as Bluetooth and WLAN

components must be disabled during a call. See Page 62 for instructions to 

disable these components.

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, and (2) this device must accept any interference received,

including interference that may cause undesired operation.

Your mobile device is a low power radio transmitter and receiver. When 

it is ON, it receives and also sends out radio frequency (RF) signals. In

August 1996, the Federal Communications Commission (FCC) adopted

RF exposure guidelines with safety levels for mobile devices. Those 

guidelines are consistent with safety standards previously set by both U.S. 

and international standards bodies: American National Standard Institute

(ANSI), National Council of Radiation Protection and Measurements

(NCRP), and International Commission on Non-Ionizing Radiation

Protection (ICNRP). Those standards were based on comprehensive and

periodic evaluations of the relevant scientific literature. The design of your

phone complies with the FCC guidelines and applicable.

NOTE: 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.

Modifications not expressly approved by this company could void the

user’s authority to operate the equipment.

For body worn operation, to maintain compliance with FCC RF exposure 

guidelines, use only accessories that contain no metallic components and 

provide a separation distance of 20 mm (0.6 inches) to the body. Use of

other accessories may violate FCC RF exposure guidelines and should be 

avoided.

This device and its antenna must not be co-located or operating in

conjunction with any other antenna or transmitter.
