In the above 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 equal M5. This
is synonymous for T ratings. This should provide the hearing aid user with "normal
usage" while using their hearing aid with the particular wireless mobile device.
"Normal usage" in this context is defined as a signal quality that is acceptable for
normal operation. 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 20.19 of the FCC Rules.
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.
