ZTE D930 Manuel D’Utilisation

 

Additional safety information 

30   

While some wireless phones are 

used near some hearing devices 

(hearing aids and cochlear implants), 

users may detect a buzzing, 

humming, or whining noise. 

Some hearing devices are more 

immune than others to this 

interference noise, and phones also 

vary in the amount of interference 

they generate. 

The wireless telephone industry 

has developed a rating system for 

wireless phones, to assist hearing 

device users find phones that may 

be compatible with their hearing 

devices. Not all phones have been 

rated. Phones that are rated have 

the rating on their box or a label 

located on the box. 

The ratings are not guarantees. 

Results will vary depending on the 

user's hearing device and hearing 

loss. If your hearing device happens 

to be vulnerable to interference, you 

may not be able to use a rated 

phone successfully. Trying out the 

phone with your hearing device is 

the best way to evaluate it for your 

personal needs. 

M-Ratings: Phones rated M3 or M4 

meet FCC requirements and are 

likely to generate less interference 

to 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.
