Troubleshooting Infrared Systems; Hard-Wired Systems - Advanced Bionics HARMONY User Manual

Troubleshooting Infrared Systems

• Are you using a good PowerCel?
• Are you using the correct program on your processor?
• Ensure that the patch cable does not entangle with the headpiece cable (as
applicable).
• Ensure that the appropriate patch cable for the make and model of infrared
system is being used.
• Proper care of the patch cable (e.g., avoid sharply bending the cable) will
maximize its life.
• Certain environmental conditions, such as the presence of large objects or
bright, direct light, may cause interference. Consider moving to another location
in the room.

Hard-Wired Systems

CAUTION: Only battery-powered devices should be connected to the Direct
Connect unless a patch cable with special electronic components
is used. Ignoring this caution could lead to damage to your processor
and/or the audio device. Further, unpleasant sensations or sounds
may be perceived by the cochlear implant user.
A hard-wired system can be described as any system that provides a direct physi-
cal connection between the audio device (sound source) and the cochlear implant
user's processor. Examples of this can include interfacing with your MP3/CD player,
auxiliary/lapel microphone, etc.
Hard-wired systems are an appealing option and are many times fairly inexpensive
to implement. However there are a few precautions to consider:
• Hard-wired systems require the use of a patch cable. The Audio Interface
Cable provided with your Direct Connect system is appropriate when connect-
ing to battery-operated devices.
• Choose interface cables that are not too long. Long cables may pose a safety
problem in which you can trip over the excess cable. In addition, long cables
increase the distance between the audio device and processor and can also
act as an antenna. Thus, they may pick up unwanted signals and degrade the
incoming quality of the signal.
