Verykool s135 - Manual (Page 25)

l Please power off the Bluetooth function while using hearing aid devices with your S135.
l Hearing devices may also be rated.
l 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
l Interference noise.

Safety and regulatory guide
l 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 8
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 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
l 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.
