Digital technology
Inside your hearing instrument, the microphone,
analog-to-digital converter, digital signal
processor, receiver and other specialized
components process sound that is directed to the
eardrum and auditory system.
The microphone picks up sound waves from
the air and converts them to electrical signals.
The analog-to-digital converter encodes the
electrical signals into a format that is usable
by the digital signal processor.
The digital signal processor has been
programmed by your Audiologist or Hearing Care
Provider to execute the required digital signal
processing for your particular hearing loss.

Inserting the battery
To insert the battery into the hearing instrument,
swivel open the door of the battery compartment.
Place the proper size battery (see "Battery" section
or consult your Audiologist or Hearing Care
Provider) in the battery compartment so that the
"+" symbol on the battery coincides with the "+"
mark on the battery compartment door.
Gently close the battery compartment. Do not force
the door shut. If it does not close easily, check to
see if the battery was inserted properly. When the
battery door is completely closed, your hearing
instrument is ready for operation (Fig. 4/Fig. 5).
