RADIO FREQUENCY INTERFERENCE STATEMENT
INFORMATION TO THE USER
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 of a circuit different
from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician
for assistance.
Changes or modification not expressly approved by the party
responsible for Compliance could void the user’s authority to oper-
ate the equipment. Connecting of peripherals requires the use of
grounded shielded signal cables.
FCC Compliance Information
This device complies with Part 15 of 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.
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 per-
sons 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.
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 hear-
ing device is relatively immune to interfer-
ence 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.
