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 microphone

LED Indicator
Battery Status Battery Status
(3-4 quick blinks) Battery charge status is good
• •
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
is established. until the headpiece is over the internal implant and communication with the internal device
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

Sound Processor Placement & Device Check
Platinum Sound™ Processor 1. Processor • Verify battery charge • Turn down the Volume • Set sensitivity to user position • Set program selector to “On” Harmony® Processor 1. Processor • Verify battery charge • Turn down the volume • Select the appropriate program
2. Platinum Sound™ Processor Establish communication • Set headpiece in place • Select the appropriate program • Verify lock 3. Turn up the volume (12:00) 4. Check the microphone 5. Behavioral listening check Harmony® Processor 2. Establish communication • Set headpiece in place • Verify lock 3. Turn up the volume (12:00) 4. Check the microphone 5. Behavioral listening check
• • •
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
FM Systems
Receiver Options
• Platinum Series Processor (PSP)

FM systems
iConnect adapter
Cable-free connectivity to standard Phonak 3-prong receivers • No compromise in PowerCel operating time • Uses one ZeniPower Zinc-Air Size 10 battery (available from Advanced Bionics) • Averages 20-30 hours of battery life
FM & Assistive Listening Devices
Direct Connection
• • • Only use with battery-operated devices Processor connects to audio input cable to device Platinum Series Processor (PSP) • Use the auxiliary input jack (on the side of PSP) Audio Interface Cable • Harmony or Auria BTE Processor • Use the Direct Connect earhook and cable
FM & Direct Connect
