Magnets should only to be changed by a CI
It is important that the magnet strength of the CI headset be tight
enough to hold the headset in place, yet not so tight as to cause problems.
If the magnet strength is too great, the blood flow to the tissue under the
magnet can be reduced or cut off causing the skin to break down. If you are
unsure as to whether your magnet strength is too great or the headset
becomes more and more uncomfortable as the day progresses, please consult
your audiologist about whether the magnet strength on your headset needs to
Adjusting the magnet strength on the Cochlear Corp. headsets is done by
turning the magnet in the headset (there is even a slot in the top of the
headset to help make this easer). Turn it clockwise to make the magnet
stronger and counter-clockwise to make it weaker. If this does not make
the magnet strength strong or weak enough, a number of alternative
strength magnets are available.
Adjusting the magnet strength on the Advanced Bionics headsets requires
the addition or removal of magnet discs from the headset.
Barb Stroer, Audiologist for Advanced Bionics tells us:
"Until September 1997, there were three different
and the strengths were indicated by different magnet colors -
orange/weakest, green, and red/strongest.
- After September 1997, only orange magnets have been
up to 5 of them can be stacked in the headpiece - three fit under the flat
magnet cover on the headpiece and if 4 or 5 are needed, then the raised
magnet cover is used. The magnetic strength is determined by
the number of
orange magnets that are placed inside the headpiece. One orange is
the least magnetic strength, 2 orange magnets are
approximately the same
strength as one green magnet and 3 orange magnets are about the same
strength as 1 red magnet.
So, a center may no longer have green or red magnets
strengths can be obtained by using the orange magnets."
Adjusting the magnet strength on the Med-El headsets requires
the addition or removal of magnet discs from the headset. My contact at
Med-El points out that as the skin flap heals, it's normal to need to
adjust the magnet strength.
