Hearing
Instruments
Your Unison hearing devices may have up to three
programs. Each program has been individually tailored
by your hearing healthcare professional to meet your
particular listening needs.
Your hearing devices are equipped with a push-button
for switching between programs. Each time you push
the program button, you will move to a new program.
Your hearing devices beep to indicate which program
you are in (i.e. one beep for program 1, two beeps for
program 2, etc.) If you prefer, your hearing healthcare
professional can adjust the pitch and loudness of the
program beep or turn it off entirely.
Adjusting the Volume
The volume on your hearing devices may adjust
automatically in response to the loud or quiet sounds
around you. If you have a manual volume control, you
can further adjust the volume on your hearing devices.
The manual volume control dial is numbered one to
four. One indicates that the volume is at the minimum
level and four indicates that the volume is at the
maximum level. Rotate the volume control upward to
increase the volume or downward to decrease the
