DIRECT AUDIO INPUT(DAI) CAPABILITY
This hearing instrument is
equipped with direct audio
input (DAI) capability. DAI
allows an external sound
source to be connected
directly to the hearing
aid via a DAI boot. You
will receive an improved
signal, when using DAI,
because the sound is fed
directly into the hearing aid, bypassing some of the
normal sources of noise. Some of the external devices
that can be connected to the DAI boot are a telephone,
a CD player, a computer etc… The DAI boot is an
optional accessory that can be purchased through
your hearing care professional.
• The sound source connects to your hearing
instrument with a cable and an audio boot.
• Thehearinginstrumentprofessionalwillsetoneof
your programs for direct audio input. To use direct
audio input (DAI), set the hearing instrument to the
DAI program (typically program 3).
• In this program, you will typically not hear any
sound from the microphone. Therefore, most
environmental sounds will not be heard in the ear
that is set to DAI. Your hearing care professional
has software to modify this program to allow
you to hear environmental sounds and DAI
simultaneously.
The hearing instrument can be turned on and off when
the DAI boot is connected:
•Turnoffbypushingthe
plug downwards
•Turnonbypushingthe
battery door shut
TELEPHONE USE
Using the telephone, while wearing your hearing in-
strument, may require some practice. Many hearing
instruments will whistle, when the phone is held up
against them. To avoid this problem, the ReSound
Sparx Lite has an induction coil. By switching the pro-
gram button to the telecoil program (typically program
2), the hearing instrument will only pick up sounds
coming from the telephone. You may need to adjust
the volume on the hearing instrument to improve
hearing understanding on the telephone. The receiver
of the telephone should be placed as shown in the
drawing below.
