HTC RHOD00 Manuel D’Utilisation

Appendix  2

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.
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.

part of comprehensive guidelines and establish permitted levels of RF energy 

for the general population. The guidelines are based on the safety standards 

previously set by international standards bodies:
