Health and Safety 185 184 Health and Safety
are likely to generate less interference to hearing devices than mobile devices
that are not labeled. M4 is the better/higher of the two ratings. M-ratings refer
to enabling acoustic coupling with hearing aids that do not operate in telecoil
mode.
T-Ratings: Mobile devices rated T3 or T4 meet FCC requirements and are likely to
generate less interference to hearing devices than mobile devices that are not
labeled. T4 is the better/higher of the two ratings. T-ratings refer to enabling
inductive coupling with hearing aids operating in telecoil mode.
Under the current industry standard, American National Standards Institute
(ANSI) C63.19, the hearing aid and wireless mobile device rating values are
added together to indicate how usable they are together. For example, if a
hearing aid meets the M2 level rating and the wireless mobile device meets the
M3 level rating, the sum of the two values equals M5. Under the standard, this
should provide the hearing aid user with normal use while using the hearing aid
with the particular wireless mobile device. A sum of 6 or more would indicate
excellent performance. However, these are not guarantees that all users will be
satisfied. T ratings work similarly.
The HAC rating and measurement procedure are described in the American
National Standards Institute (ANSI) C63.19 standard.
Restricting Children’s Access to Your Mobile Device
Your mobile device is not a toy. Do not allow children to play with it because
they could hurt themselves and others, damage the mobile device, or make
calls that increase your mobile device bill.
Keep the mobile device and all its parts and accessories out of the reach of
small children.
