Troubleshooting Tips
• Ensure that the appropriate patch cable for the make and model of FM system is being
used. Do not substitute cables with unknown properties without first consulting your
implant-care professional, Advanced Bionics or the FM manufacturer.
• Proper care of the patch cable (i.e. avoid sharp bending of the cable) will maximize
it’s life.
Infrared Systems
Infrared systems use invisible light-waves to transmit signals such as speech or music.
Infrared light is invisible as the wavelength of the signal is beyond the capability of
our eyes to see. The transmitter/emitter uses the infrared light-waves to send a signal,
such as speech or music, to an individual wearing a wireless infrared receiver. The
infrared system may be a small personal system or a system comprised of large
panels or light-emitting diodes (LED) and few individual receivers. In large group
situations, these emitters are mounted high on a wall, and aimed at the perspective
audience. Inside of an infrared receiver is an infrared sensitive receiving diode.
Some infrared receivers have an audio output socket that will allow the implant
recipient to patch the signal directly into the audio-input socket of the sound
processor. A specially designed patch cable can be obtained from a variety of sources
including the manufacturer of the infrared systems.
Note that not all infrared receivers have body worn environmental microphones or
have an extra audio socket for an auxiliary microphone. Thus your audiologist will
help select an appropriate mixing ratio between the built-in HiRes Auria Processor
microphone and the signal from the infrared receiver.
Operating Instructions
• Ensure that the appropriate patch cable has been obtained for the make and
model of the infrared system and the HiRes Auria Processor.
• With the infrared system and processor in the off position attach the appropriate
ends of the patch cable to their respective input/output sockets.
• Set the infrared volume dial of the receiver to the minimum setting.
• Set the volume dial of the HiRes Auria Processor to the user’s typical use settings.
• In sequence, turn on the infrared system transmitter, receiver and processor in
that order.
• Increase the infrared system volume dial to a comfortable listening level or to a
specifically recommended level by the infrared system manufacturer.
