Auria® Sound Processor
PowerPak*
• Can be used instead of a PowerCel
• Uses one AA battery and provides longer operating
times before a battery change is required
• Attaches to the student’s clothing
*This option is ONLY
compatible with the
Auria processor
Using Ear Level Sound Processors
• How do you turn the BTE on and off?
• Placing the PowerCel on the processor turns
the processor on
• To turn the processor off, remove the PowerCel
BTE Processor Microphone Check
• Harmony has a built in amplifier
• Requires an open program position
• Direct Connect System & headphones provides
access to the processor microphone
• Auria does not have a built-in amplifier
• Direct Connect System and a RadioShack portable
amplifier (speaker) provides access to the processor

following:
1. Battery charge status, then
2. Lock status, and finally,
3. Microphone system status

LED Indicator
Battery Status
• Lock Status
• Information regarding the communication link between
the sound processor and internal cochlear stimulator
• After the battery charge sequence the LED will continue to
flash red once per second until the headpiece is over the
internal implant and communication with the internal device
is established.
LED Indicator
Microphone System Status
•
•
Indicates the microphone is picking up sound and
transmitting to the internal cochlear stimulator
After the battery and lock status sequences the LED should
flash green to loud speech
LED Indicator
IntelliLink™ Implant ID
Safety Feature
• A feature to assure that the correct processor and implant
are being connected
• A rapidly blinking red light indicates:
• Wrong processor
• In rare instanced, that there is a processor error condition
Platinum Sound™ Processor
Audible Alarm

•
Optional feature designed primarily for children
Alerts the caregiver or teachers when the system:
• is not transmitting sound to the implant
• beeps once each second until proper lock status is
achieved
OR
• the battery is near depletion
• slow beeping tone until the battery dies or is
replaced
**Only available on the PSP

Behavioral Listening Check
• Purpose:
• Confirm that the child has access to
meaningful sound with the cochlear implant
• Tools:
• Working cochlear implant system
• Age appropriate materials
• Acoustic Screen
• Ling Six Sound instructions
• Documentation:
• Establish a baseline
• Chart progress
Troubleshooting
Keys to Success:
• Access support: on-line & on-call
• Keep tools on hand
• Daily listening checks
Troubleshooting the Sound Processor
•
When the child stops responding to sound as
expected:
1. Visually inspect the student’s equipment
2. Verify processor settings
3. Check the battery status using the LED
Troubleshooting the BTE Processor
•
What can you do to troubleshoot the sound processor?
• Change the battery
• Replace the integrated headpiece cable
• Listen to the microphone
• Reminder: the processor must be set to an empty
program slot
• Harmony – use microphone tester headphones
• Auria – use RadioShack speaker
**If the microphone is faulty, plug in the auxiliary
microphone to provide a different sound source
Troubleshooting the PSP
•
What can you do to troubleshoot the sound
processor?
• Use the LED sequence to determine what the
problem may be
• Change the battery
• Change the cable
• Listen to the headpiece microphone with the
microphone tester earphone -change the
headpiece if warranted
• Plug in the auxiliary microphone to provide a
different source for microphone pick up
FM Systems
• Frequency modulated (FM) systems are composed of a
teacher-worn transmitter (microphone) and a receiver worn
by or positioned close to the child
• Teacher’s voice is captured by the transmitter (via the
microphone) and sent wirelessly to the receiver via radio
waves
Microphone
Transmitter
Receiver
• An FM system brings the teacher’s voice directly to the
student and is designed to:
• Improve listening in noisy, reverberant classrooms
• Overcome the problems of listening at a distance
