volume. Note that your volume control may be disabled
by your hearing healthcare professional and, therefore,
could be inactive.
Setting Your Ideal Volume
Unison hearing instruments equipped with manual
volume control have an ideal volume indicator. A single
beep indicates when the volume control has reached its
ideal level for your particular hearing loss, as pre-set by
your hearing healthcare professional.
Listening in Quiet and Noisy Environments
Your Unison hearing devices have a directional
microphone system which focuses on sounds in front of
you (i.e., speech) while reducing sounds from the sides
or behind you (i.e., noise). Your directional system is
activated by the push of the program button. Your
hearing healthcare professional will tell you which
program(s) contain the directional microphones.
Replacing the Microphone Protectors
Your Unison hearing devices have a shield to protect the
microphones from dirt and debris. Debris on the
microphone protector reduces the sound quality of the
instrument. You should have the microphone protectors
replaced by your hearing healthcare professional
approximately every three months to ensure optimal
sound quality.
