Using the
telephone while
wearing your
HD85
Close proximity to a telephone can sometimes cause hearing
instruments to make a squealing sound, also known as feedback.
To reduce the potential for this problem, your system is equipped
with feedback suppression, which greatly reduces the chance of
feedback.
Further measures to avoid feedback include positioning 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.
