Telephone Compatibility
Most, but not all, landline phones are Telecoil compatible. Wireless and
cellular phones rated T3 or T4 are Telecoil compatible (T4 is preferred).
Check your telephone's instruction manual to nd out its rating. Phones
rated M3 or M4 are not Telecoil compatible but are hearing aid compatible.
M3 and M4 phones will work with Programs 1-3. The speaker function on
your phone also works well with your MDHearingAid Hearing Aids.
Compatible Loop Systems
The Telecoil Program can also help you listen in public
places equipped with Telecoil compatible assisted
listening systems. When the sign to the right is
present, it signies a Telecoil system is available.
If your Hearing Aids do not operate when the
Telecoil is ON, the loop system may not be operating
or you may be in a "dead" spot. Try positioning yourself
in a different part of the looped area, or return your
Hearing Aids to your preferred Program 1-3 and sit
as close to the speaker as possible.
