Introduction • Cochlear Implant Manufacturers – Cochlear Americas (Nucleus) – Advanced Bionics (AB) • Also known as Clarion – Med-EL
Introduction • Each manufacturer supports multiple sound processor models. • Each manufacturer has “current” sound processor technology that is back-ward compatible with “older” implant technology. • Each sound processor requires slightly different troubleshooting procedures.
Troubleshooting made easy. . . Identical Main Modules Different Controllers
Recommendations for Schools • At least one person at school become familiar with the student’s sound processor. • Learn the model name of your student’s sound processor. • Learn the components or parts of the sound processor by name. • Practice preventative maintenance
Troubleshooting Toolbox • Be prepared to troubleshoot • Work with the parents & audiologist to have the following on hand: – Appropriate back-up batteries – Appropriate battery holder/rack – Monitor Headphones – Signal Check – Back-up transmitting cables – Lapel or Auxiliary Microphone
Nucleus Freedom Standard BTE Sound Processor • Sound Processing Module • Microphone(s) • Transmitting Coil/Cable Coil • Coil & Magnet • Controller • Batteries or Rechargeable Battery Module
Nucleus Freedom Body Worn Sound Processor • Sound Processing Module • Microphone(s) • Transmitting Cable/Coil • Coil & Magnet • Controller Shoe & Cable • Batteries or Rechargeable Battery Module
Nucleus Esprit 3 G Sound Processor • Microphone(s) • Transmitting Cable/Coil (missing in slide) • Coil & Magnet • (missing in slide) • Controls • Battery module
Advanced Bionics Harmony BTE Sound Processor and Components • Sound Processing Module & Controller • Microphone & Ear Hook • Transmitting Cable/ Coil • Coil & Magnet • Rechargeable Battery Module
Advanced Bionics Harmony BTE Sound Processor and Components There are two other models of BTE processors Auria Platinum/CII BTE
MED-EL Ear-level Speech Processors • Tempo+/OPUS 1 – Program/volume switches – Sensitivity dial • OPUS 2 – Switch free design – Fine. Tuner™
MED-EL Tempo+ BTE Sound Processor • Sound Processing Module & Controller • Microphone(s) • Transmitting Coil & Magnet • Transmitting Cable • Ear Hook • Battery Module
MED-EL Opus BTE Sound Processor • Sound Processing Module & Microphone(s) • Coil & Magnet • Transmitting Cable • Earhook • Battery Module • Connecting piece
Basic Troubleshooting Concepts • Establish a two-way communication & notification method with the student’s parent. • Incorporate an action plan for daily equipment checks into the student’s IEP
Basic Troubleshooting Concepts • Establish reliable speech-base feedback tools to use for daily listening check. – – Ling 6 sounds test (aa, oo, ee, sh, ss, mm) Closed set spondees (baseball, airplane) Closed set words (colors, familiar names) Open set words/sentences (What did you eat for breakfast; Who drove you to school).
Ling 6 Sound Check
Cochlear Implant Accessories – to have on hand • • Monitor Headphones Lapel or Auxiliary Microphone Signal Check or System Sensor Battery Charging System Earhooks (T-Mic, Direct Connect, etc) Audio or Interface Cables User Manual (CD)
Nucleus Freedom BTE Accessories • Monitor Headphone • Lapel or Auxiliary Microphone • Signal Check/System Sensor • Battery Charging System • Earhooks (T-Mic, Direct Connect, etc) • Audio or Interface Cables • User Manual (CD)
Sprint Body Worn Accessories • Monitor Headphone • Lapel or Auxiliary Microphone • Signal Check/System Sensor • Battery Charging System • Audio or Interface Cables • User Manual (CD)
Freedom Sound Processor Help Messages
Freedom Sound Processor Help Messages • H 1 = Battery flat – Check for proper battery insertion – Change batteries; change battery holder • H 2 = Battery low – Change batteries • H 3 = Coil error – Check for proper coil insertion & placement – Check for cable damage – Change coil
Freedom Sound Processor Help Messages • H 4 = Sound/stimulation error – – – Turn processor “Off”, “On” Check/change microphone protector cover Check/change coil Check sensitivity & volume settings > 0 Use the lapel microphone to sound processor check microphone – Contact parent &/or student’s cochlear implant center
Freedom Sound Processor Help Messages • H 5 = MAP corrupt – Try alternate program – Contact student’s cochlear implant center • H 6 = RF interference – Contact student’s cochlear implant center
Harmony Sound Processor Help Messages
Harmony BTE 3 Color Help Messages • Red: – A communication error with implant – Processor/ear is mismatched – Headpiece off or loss of communication • Green: – Microphone is working – Program slot is empty • Orange: – Battery is low – Battery needs to be changed/dead – Battery charge status
MED-EL: Verifying normal equipment function • The red LED will illuminate 4 -5 seconds when the processor is first activated (brief flashes for Opus 2) • This uploads the map, & performs a diagnostic check. • LED light continues to blink only when communicating a problem.
LED Indicator in MED-EL Processors • • Processor status Program errors Low battery Flashing patterns can be deactivated by the CI audiologist
MED-EL TEMPO+/OPUS 1
Fine. Tuner Tips • Not needed during the day unless: – Child has need of the telecoil feature – Child needs to make a program or volume change • If processor batteries are changed, it reverts to the same settings previously in use – One exception: Telecoil on reverts to mic on
Basic Troubleshooting Concepts • Check for power – Processor turned on & in proper program – Check for visible signal light or LCD display – Replace batteries
Power Options • Ask parents to provide disposable battery pack option
Basic Troubleshooting Concepts • Check for visible defects – Frayed cables – Cracked casing or controller – Loose connections • Cables, component parts, batteries
Basic Troubleshooting Concepts • Check Transmitting Coil & Cables – Steps: 1. Confirm that cable(s) is plugged in correctly. 2. Hold the signal check over the transmitting coil when power is on.
Basic Troubleshooting Concepts • Check Transmitting Coil & Cables – Steps: 3. Red light should illuminate. 4. Replace transmitting coil one at a time; apply signal check after each component change. 5. Check microphone if no transmission. MED-EL signal check: Nucleus:

Microphone Check
Basic Troubleshooting Concepts • Microphone Check Steps: – Turn off sound processor – Attach monitor headphones – Turn sound processor on – Perform listening check • Use Ling sounds & running speech • Own voice should be clear & static free • Move cables around & listen for static or intermittency – Apply Aux mic & compare sound
Use of Auxiliary Microphone • When the student’s headset or sound processor microphone produces no sound or sound of poor quality, the Aux/Lapel microphone may be used until a replacement microphone is available • Attach the lapel mic outside the student’s shirt, near the chin, and away from objects that may produce sound interference (e. g. jewelry).
Don’t forget about the internal device • When all else fails – refer the student back to the implant center &/or surgeon
Other Learning Tools • Join the hands-on demonstration at today’s Break-Out Sessions. • Accompany your student to the CI Center for a mapping session. • Attend the Greater Cleveland Cochlear Implant Support Group Meetings – 3 per year.
