1. Roll the Fun-Tak, provided with
each instrument, into a rod long
enough to go around the transmitting
end of the aid (approximately 2
inches). (Modeling clay can also be
used, but it doesn’t work as well.)
2. Bend the Fun-Tak rod around the
canal of the aid, making the resulting
“donut” flush with the end of
the aid. (Some users choose to seal
the vent opening at this end with a
small amount of Fun-Tak.)
3. Align the sound opening of the aid
to the hole at the conical end of
the coupler. Look through the open
end of the coupler to be sure the
sound opening of the aid is clear of
obstructions and correctly placed.
4. Seal any vent on the aid with a
small kernel of Fun-Tak.
