HTC EVO Shift 4G Manuel D’Utilisation

Please power off the Bluetooth function while using 
hearing aid devices with your PG06100.

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 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.

Hearing devices may 
also be rated. 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 
interference noise.
