TROUBLE SHOOTING
The sound processor contains sensitive micro-
electronic technology and should be opened and
repaired only by Symbion, Inc. servicing personnel.
However, there are some things you should verify
before contacting Symbion, Inc.
If you do not hear anything when the sound
processor is turned on make sure the battery was
inserted correctly and check al l the cable connec-
tions. Be sure to turn the sound processor off before
you begin. If the cable has a short and you do not
turn the sound processor off you may experience
an uncomfortable noise. Check the cables to be
certain they are properly connected but do not try
to fo rce them. If your cab le has a short it will need
to be replaced .
If the sound quality is normal for a few minutes
then quickly deteriorates you may have bad bat-
teries. When batteries begin to wear out they may
work for a few minutes each time you switch the
sound processor on and then stop. Replacing the
batteries may solve this problem.
If you still cannot hear as well as usual, readjust
your volume and sensitivity controls. They may not
be on the best setti ng for the particula r situation you
are in. Remember, if you are in a noisy environment
or are feeling tired the sound quality will not be as
good as usual.
Contact your audiologist if you have any con-
cerns. Your audiologist will check on you occasion-
ally but you should not wait for his/her next call if
you need something taken care of immediately.

Infection
If you contract an infection in the area of the
percutaneous pedestal, there is a remote possibility
