Using the Telephone / Telecoil Program
The MDHearingAid
®
AIR is equipped with a Telecoil Program. Telecoils, also
known as Audio Induction Loops, enable the direct magnetic coupling of your
Hearing Aid to compatible telephones and other audio sources.
Telecoils provide clear sound that is free of background noise and feedback.
Telecoils enable you to comfortably use the telephone without removing
your Hearing Aid.
To activate the Telephone/Telecoil mode (Program 4)
Push the Program Button until you hear four tones. In Telecoil mode,
the Hearing Aid microphone is disabled; only the sounds picked up
from the Telecoil are amplified through the Hearing Aid.
General Telephone Use
When using the Telecoil, be sure to center the telephone receiver over
the Hearing Aid, NOT your ear canal. Move the receiver along the
Hearing Aid to locate the clearest, strongest signal. You may have to
increase the volume of the Hearing Aid slightly. To return to normal
listening, push the Program Button until the desired program is reached.

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 find 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
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 signifies 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.
