Turning the Hearing Aid On
The MDHearingAid
®
AIR uses a
volume dial with a built in on/off switch
(like traditional radios).
Turn off the hearing aid, by turning the
volume dial downward below 1 until
you feel a click. The hearing aid is
now off.
Turn the volume dial upward, past
the click, and the hearing aid is now
turned on.
When the hearing aid is turned on it will take a few seconds to begin
amplifying sound. This designed to allow the user time to put the hearing
aid in their ear.
WHISTLING may be heard if the hearing aid is turned on but not securely in
your ear. This is normal. Once the hearing aid is properly seated in your ear,
the whistling will stop (read on).
