Health and Safety Information 231
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.
