Sanyo M1 Cell Phone User Manual


 
252 Section 4A: Important Safety Information
Using Your Phone With a Hearing Aid Device
Your phone has been tested for hearing aid device compatibility.When 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 ratings for some of their mobile phones, to
assist hearing device users in finding phones that may be compatible with their hearing
devices.Not all phones have been rated. Phones that are rated will have the rating on the
box.
Your M1 has an M4 rating.
The M3/M4 ratings do not guarantee successful interoperation between your phone and
hearing aid device.Results will vary depending on the level of immunity of your hearing
device and degree of your hearing loss.
The more immune your hearing aid device is,the less likely you are to experience
interference noise from your wireless phone.Hearing aid devices should have ratings similar
to phones.Ask your hearing healthcare professional for the rating of your aids.Most new
hearing aids have at least an M2 immunity level.Add the “M” ratings of your hearing aid and
your phone to determine probable usability:
Any combined rating equal to or greater than six offers best use.
Any combined rating equal to five is considered normal use.
Any combined rating equal to four is considered usable.
Thus,if you pair an M3 hearing aid with an M3 phone, you will have a combined rating of six
for “best use.”
Qwest further suggests that you experiment with multiple phones (even those not labeled M3
or M4) while in the store to find the one that works best with your hearing aid device.Should
you experience interference or find the quality of service unsatisfactory after purchasing your
phone,promptly return it to the store where purchased for exchange or refund.
Note:
Phones rated M3 or M4 meet FCC requirements and may generate less
interference to hearing devices than phones that are not labeled. M4 is the
better/higher of the two ratings.
