Batteries Cont’d
and Choosing Domes
Low Battery Warning
When the battery life is expiring, you will hear a low battery
warning (one short beep). This warning will continue
intermittently until you replace the old battery with a fresh
new one. After the first warning, it is normal to experience
some reduction in sound quality.
Choosing The Correct Dome
Your HearClear™ HCZ3 is shipped with a variety of domes in
different sizes and styles. This allows you to select the dome
that provides you with maximum comfort and hearing.
Open Style Domes
Open domes have openings for sound
to pass through from outside of the
hearing aid. They are intended for people
with noticeable to moderate and high
frequency losses. These domes work
great for people who use lower volume
settings (because whistling may occur
with higher volumes). The openings allow
some natural sound to pass into your ear
and provide more ventilation.
Closed Domes
Closed domes provide a seal for the ear
canal, which helps trap sound. These
domes offer more volume and are helpful
to those who have trouble hearing low
frequency sounds. They can also help
eliminate feedback.
