installation. If this equipment does cause harmful interference to radio or TV reception, which can be

FCC RF EXPOSURE INFORMATION

In August 1996, the Federal Communications Commission (FCC) of the United States with its action in

Report and Order FCC 96-326 adopted an updated safety standard for human exposure to radio frequency

electromagnetic energy emitted by FCC regulated transmitters. Those guidelines are consistent with the

safety standard previously set by both U.S. and international standards bodies. The design of this device

complies with the FCC guidelines and these international standards.

Modifications

The FCC requires the user to be notified that any changes or modifications made to the device that are

not expressly approved by High Tech Computer Corporation may void the user’s authority to operate the

equipment.

FCC Hearing-Aid Compatibility (HAC) Regulations for Wireless Devices

On July 10, 2003, the U.S. Federal Communications Commission (FCC) Report and Order in WT Docket 01-

309 modified the exception of wireless phones under the Hearing Aid Compatibility Act of 1988 (HAC Act)

to require digital wireless phones be compatible with hearing-aids. The intent of the HAC Act is to ensure

reasonable access to telecommunications services for persons with hearing disabilities.
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. IRIS100 is rated

M3.
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 for better use. A sum of 8 is considered for the 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 should provide the hearing aid user with “normal usage” while
