Sanyo Sprint SCP-7000 Operating Manual page 70

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."
We further suggests 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 after purchasing your phone, promptly return it to the store. With our 14-day Risk-Free
Guarantee you may return the phone within 14 days of purchase for a full refund.
