Volume control
To adjust the volume, rotate
the volume control using your
fingertip. There are numbers on
the dial that shows the volume
setting. The number “1” is the
lowest while “4” is the loudest.
Note that before fitting the
hearing aid it is good practice to
set the volume to “1” and then
adjust the volume higher to your
liking after fitting. You may hear
whistling sounds when your
hand is near the hearing aid if
the volume is set too loud. If the
whistling sound still remains
when your hand is away from the
hearing aid then you should turn
down the volume.
