Troubleshooting Tips
• Ensure that the appropriate patch cable for the make and model of infrared system
is being used. Do not substitute cables with unknown properties without first
consulting Advanced Bionics or the infrared systems manufacturer.
• When the infrared systems manufacturer and/or Advanced Bionics have made specific
setting recommendations, they have been made under specific conditions.
• Certain environmental conditions, such as the presence of large objects blocking
the pathway of infrared systems light from the infrared systems transmitter to the
infrared systems receivers can cause interference. Consider moving to another
location in the environment.
• Proper care for the patch cable (i.e. avoid sharp bending of the cable) will maximize
its life.
Hard-wired Systems
A hard-wired system can be described as any system that provides a direct physical
connection between the sound source and the listener. Examples of this type of
system include the use of the Auxiliary Microphone available through Advanced
Bionics, pass around microphones with long extension cables, and patch cables for
use with battery-powered appliances such as Walkman and CD players. While this
type of assistive technology is typically the least expensive and the easiest to
implement it has its limitations. There is the “safety factor” of having long cables to
trip over and the distance limitation before the audio signal will become degraded
due to electrical losses from the long cable lengths. Further, long cables tend to act
as an antenna, and if not properly designed and can pick up unwanted signals.
CAUTION: One must not plug AC powered devices (e.g. TV, Stereo, Computer) into
the HiRes Auria Processor without the use of an approved patch cable
that has electrical surge protection built into its design. Ignoring this
caution could lead to damage to the sound processor and/or to the
recipient with unpleasant sensations or sounds.
Operating Instructions
• As with any patch cable one must determine if the hard-wired system has a plug
that will fit into the audio-socket of the processor. The HiRes Auria Processor uses
a standard 3.5mm socket. The audio socket of the processor is designed to accept
a stereo input. While you may not be able to find a patch cable for all audio devices
such as CD players, tape recorders, etc. At an audio appliance outlet, there are a
number of third-party vendors that can provide an appropriately made cable for
your needs. Please contact Advanced Bionics for a list of these vendors.
