Because of the placement of the
microphone in your ear canal, you may
use any phone in the same manner as
you did prior to being fit with your Cue
hearing instrument. If feedback (whistling)
occurs, slightly pull the phone away from
your ear.
Telephone Use
Cell Phone Compatibility
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/T2)
and a telephone rating of 3 (M3/T3) 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 M4. The
equipment performance measurements,
categories and system classifications are
based upon the best information available
but cannot guarantee that all users will
be satisfied. For your cell phone to be
compatible with these hearing instruments,
the cell phone immunity rating of M1 or
higher is required. Please consult your cell
phone specifications for your cell phone
immunity rating.
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.”
