Using the Telephone While Wearing your Hearing System
Close proximity to a telephone can sometimes cause hearing in-
struments to make a squealing sound, also known as feedback.
To reduce the potential for this problem, your system is equipped
with a feedback management system, which greatly reduces the
chance of feedback. Further measures to avoid feedback include
position ing the phone close to the hearing instrument, but not
directly on the instrument. If there is feedback, it may take a few
seconds for the instrument’s signal processing to adapt. This
technique may require practice.
The Telecoil Feature
Your hearing system has a built-in telecoil, and your hearing healthcare professional may
have programmed one of your listening programs to take advantage of it. When a telecoil
is activated, the hearing instrument will only detect and process sounds from coming
from the telephone.
To activate the telecoil you will need to use the memory selector to activate the appro-
priate memory.
To use the telephone while the telecoil is activated, position the telephone near, but not
directly on the instrument. You may need to re-position to find the best reception.
Cellular Phone and Hearing Instrument Compatibility
Hearing instrument performance with cellular phones may vary based on the individual
hearing system or the cell phone being used. If your hearing system and cell phone are
not compatible you may experience a buzzing or clicking noise while using the two in
conjunction. If this is the case with your current hearing system and cell phone, consult
with your hearing healthcare professional to see if there are options to improve the sound
quality
Measures you can take to prevent this situation:
• When purchasing a hearing system, be sure to test it with your existing phone to
determine compatibility.
• When shopping for a new cell phone, be sure to test it with your hearing system
before purchasing.
For additional guidance, please consult your cell phone provider.
