Your IMPACT hearing instrument is
fully automatic. There is no need to
manually adjust the volume control.
However, if you prefer manual
volume control, your IMPACT hearing
instrument can be programmed for
manual adjustment. This will be
done by your NHS audiologist.
If your system is
programmed for
manual adjustment,
the wheel-shaped
volume control can
be rotated up
(louder) or down
(softer) to select
the desired
listening volume.

Using the volume control
Rotate the wheel
upwards to increase
volume. Rotate it
down to decrease
volume.
To increase volume, place your
index finger gently against the
volume control wheel and rotate it
upward. If your system is equipped
with a warning tone for volume
control limits, once it is heard,
adjusting the volume control further
in that direction will have no effect.
To reduce the volume, rotate the
wheel in the opposite direction.
