ZTE Z797C 用户手册

This phone has been tested and rated for use with 
hearing aids for some of the wireless technologies that 
it uses. However, there may be some newer wireless 
technologies used in this phone that have not been 
tested yet for use with hearing aids. It is important to 
try the different features of this phone thoroughly and 
in different locations, using your hearing aid or cochlear 
implant, to determine if you hear any interfering noise. 
Consult your service provider or the manufacturer of 
this phone for information on hearing aid compatibility. 
If you have questions about return or exchange policies, 
consult your service provider or phone retailer.
M-Ratings: Phones rated M3 or M4 meet FCC 
requirements and are likely to generate less interference 
with hearing devices than phones that are not labeled. 
M4 is the better/higher of the two ratings.
T-Ratings: Phones rated T3 or T4 meet FCC 
requirements and are likely to be more usable with a 
hearing device’s telecoil (“T Switch” or “Telephone 
Switch”) than unrated phones. T4 is the better/higher 
of the two ratings. (Note that not all hearing devices 
contain telecoils.)  
Your Z797C has been tested for hearing aid 
device compatibility and has an M4/T4 rating.
Hearing devices may also be rated. Your hearing device 
manufacturer or hearing health professional may help 
you find this rating. For more information about FCC
