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:
䢇
Any combined rating equal to or greater than six offers best use.
䢇
Any combined rating equal to five is considered normal use.
䢇
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.”
Sprint 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 the Sprint
14-day Risk-Free Guarantee you may return the phone within 14 days of
purchase for a full refund.
Getting the Best Hearing Device Experience
With Your Phone
To further minimize interference:
䢇
There is usually less interference on the microphone setting than the
telecoil setting.
䢇
Use phones with a pull-out antenna. Phones with embedded
antennae may produce more interference.
䢇
Position the phone so the antenna is farthest from your hearing aid.
䢇
Move the phone around to find the point with least interference.
䢇
Set the phone’s Display and Keypad backlight settings to ensure the
minimum time interval:
1.
Select Menu > Settings > Display > Main Display > Backlight time-out .
2.
Select Always off .
3.
Press Select > Yes .
