Telephone Use
your hearing instrument is equipped with an induction coil
(telecoil) which picks up magnetic emanations from a hear-
ing instrument compatible telephone. your hearing care
professional can activate the telecoil. By selecting the tel-
ecoil programme, the hearing instrument will only pick up
the sounds coming from the telephone.
When using the telecoil programme, the receiver of the tele-
phone should be held as shown in the drawing. you may
need to move the handset around slightly to find the best
reception.
If you do not wish to have a telecoil programme, you may
still use the phone while wearing your hearing instrument.
many hearing instruments will whistle (feedback) when in
close proximity to a telephone. To reduce the potential for
this problem, your hearing instrument is equipped with an
adaptive digital feedback suppression (Dual Stabilizer DFS)
system which allows for use of the telephone while greatly
reducing the chance of feedback. Hold the phone close
to the top microphone of the hearing instrument, but not
directly on it. If there is feedback, it may take a few seconds
for the instrument to adapt.
Using the telephone, while wearing your hearing instrument,
may require some practice.
