Step 6: Turn the
MDHearingAid
AIR
On
The MDHearingAid AIR uses a Volume Dial
with a built in on/off switch (like a radio).
To turn the Hearing Aid ON, turn the
Volume Dial upward, past the click.
To turn the Hearing Aid OFF, turn the Volume
Dial downward past 0 until you feel a click.
IMPORTANT: When the Hearing Aid is turned
ON, it will take a few seconds to begin amplifying
sound. Please raise the volume SLOWLY
to avoid a sudden blast of sound.
WARNING: Whistling may be heard if the
Hearing Aid is turned ON but not positioned
securely in your ear. This is normal. Once
the Ear Dome is properly inserted in your
ear, the whistling will stop.
