Fitting and Assembly
Step 1: Select the Correct
Ear Dome Size
Your MDHearingAid
®
PRO comes with
clear Traditional Tubing and five different
sized silicone Ear Domes to fit most
adult ears. Test the Ear Dome size by
attaching Ear Dome to Tubing before
inserting into ear canal.
Attach Ear Dome to Tubing
a)
Hold the Elbow of the Tubing with
one hand and hold the ‘mushroom’
top of the Ear Dome with the other hand.
b)
Push the Ear Dome over the ridges
on the end of the Elbow.
c)
Pull lightly in the reverse direction
to make sure the Ear Dome is
attached securely.
Insert Ear Dome in Ear Canal
Hold the Elbow of the Tubing (with Ear Dome attached) and insert
Ear Dome into the ear canal. The Ear Dome should nestle in the ear
canal without force (similar to placing a sink stopper into a sink).
The ‘mushroom’ top of the Ear Dome should be in the ear canal
and not protrude into the outer bowl of the ear.
Test Ear Dome for Fit
• Turn head side to side and simulate chewing.
If the Ear Dome pops out, it is too big.
• Nod head towards the ground. If the Ear
Dome slips out easily, it is too small.
When the Ear Dome is too small, there is
space between the Ear Dome and the ear
canal, and you may hear whistling when the
Hearing Aid is on.
Repeat the steps above with different sized
Ear Domes to find the best fit for you.
