T-Ratings: Phones rated T or T4 meet FCC requirements and are likely to be more usable with a hearing aid's telecoil
than phones that are not rated. T4 is the better/higher of the two ratings. PB100 is rated T.
Please power off the Bluetooth function while using hearing aid devices with your PB100.
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 better use. A sum of is considered for best use. In the above example,
if a hearing aid meets the M level rating and the wireless phone meets the M level rating, the sum of the two
values equal M5. 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.
This methodology applies equally for T ratings. 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 0.19 of the FCC
Rules. The HAC rating and measurement procedure are described in the American National Standards Institute (ANSI)
C6.19 standard.
