Operation
Telecoil and manual Switching
Hearing instruments with a manual telecoil allow
you to switch the devices to telephone mode
when needed.
Manually switched telecoils are activated
by choosing the telecoil setting using the
control surface.
general Telephone use
Some hearing instruments
work best by holding the
phone close to, but not fully
covering your ear. In some
instances, if you encounter
whistling (feedback), tilt the
receiver at an angle until
the whistling stops. Your
hearing professional can give
instructions and techniques
for your specific needs.
Operation
DISCLAIMER – Some hearing aid users have
reported a buzzing sound in their hearing aids when
they are using cell phones, indicating that the cell
phone and hearing aid may not be compatible.
According to the ANSI C63.19 standard (ANSI
C63.19-2006 American National Standard Methods
of Measurement of Compatibility Between Wireless
Communications Devices and Hearing Aids), the
compatibility of a particular hearing aid and cell
phone can be predicted by adding the rating for
the hearing aid immunity to the rating for the
cell phone emissions. For example, the sum of a
hearing aid rating of 2 (M2) and a telephone rating
of 3 (M3) would result in a combined rating of 5.
Any combined rating that equals at least 5 would
provide “normal use”; a combined rating of 6 or
greater would indicate “excellent performance.”
The immunity of this hearing aid is at least M2. The
equipment performance measurements, categories
and system classifications are based upon the best
information available but cannot guarantee that all
users will be satisfied.
NOTE: The performance of individual hearing aids
may vary with individual cell phones. Therefore,
please try this hearing aid with your cell phone
or, if you are purchasing a new phone, be sure to
try it with your hearing aid prior to purchase. For
additional guidance, please ask your cell phone
provider for the booklet entitled “Hearing Aid
Compatibility with Digital Wireless Cell Phones.”
