Harmony™ Sound Processor We encourage you to review the processor components before proceeding.
Choose from the item below that best describes your situation: I want to learn how to perform a task I need help with troubleshooting a problem Back
How do I……… • Check the device each day? • Connect to an FM system? Back Main Menu
How to Verify the Child’s Device is Working 1. Is the PowerCel in place and fully charged? • • Sliding the PowerCel on the Processor module will turn the device on You should see 3-4 quick Orange blinks verifying the PowerCel is fully charged 2. Is the Headpiece cable plugged into the processor module? • Check to see the cable is not twisted or frayed 3. Is the Earhook properly positioned? • • Back To Attach: Align the Earhook flush with the Harmony and push to snap in place.
How to Verify the Child’s Device is Working 4. Is the Program Selector in the desired position? • The Harmony can store up to 3 programs (P1, P2, P3). The Program Switch has three positions to represent each program. P1 is at the bottom, P2 is in the middle and P3 is at the top. 5. Is the Volume Control in the 12 o’ Clock position? 6. Is the Processor in a comfortable position behind the ear? • Back An Earmold, Huggie or Toupee Tape can be used to help secure the processor on the child’s ear.
How to Verify the Child’s Device is Working 7. Is the Headpiece positioned over the Implant (internal device)? • • You should feel the magnetic attraction You should also see the LED flash GREEN in response to loud sounds 8. Perform a Behavioral Listening Check • • Back Use the Ling Six Sound Check to verify that the child is able to detect all aspects of speech.
Performing a Behavioral Listening Check • Using the Ling Six Sounds (ah, ee, oo, sh, s and mm) you can determine a cochlear implant’s effectiveness by verifying that the child is able to detect all aspects of speech as the six sounds encompass the frequency range of all phonemes.
Connecting to an FM System 1. Ensure that you have the appropriate equipment. • iConnect Earhook • MLxS • Transmitter 2. Ensure that the FM system is functioning appropriately by listening to the FM system through an amplified speaker or walkman-style earphones. 3. Make sure all components are turned off 4.
Connecting to an FM System 5. Insert a size 10 zinc air battery into the iConnect 6. Turn down the volume on the Harmony Processor 7. Turn on the FM transmitter, MLxS, and slide the PowerCel onto the Harmony 8.
Connecting to an FM System 9. Gradually turn up the volume on the Harmony Processor 10.
I need help troubleshooting the following: • Child is NOT responding to Sound • The Light (LED) on the Processor is Flashing • Sound appears to be Intermittent • Headpiece will not stay on • Child’s voice sounds muffled or different Back Main Menu
Child is NOT responding to sound— *Note you have verified no response with a behavioral listening check. 1. Verify the Sound Processor is ON • Remember that sliding on the PowerCel turns the processor on 2. Check your connections including PowerCel, Earhook and Headpiece-Cable • Make sure they are secure 3.
Child is NOT responding to sound— *Note you have verified no response with a behavioral listening check. 4. Is the Headpiece positioned over the implant site? • Busy children can knock it off and may not be able to put it back in place. 5. Is your PowerCel charged and inserted properly? • The LED will flash 3-4 quick Orange flashes letting you know it is fully charged. 6. Are you using the appropriate program? • Back You may need to check with the parent or audiologist for this information.
Child is NOT responding to sound— *Note you have verified no response with a behavioral listening check. 7. Check the Microphone/System Status using the LED • I would like to learn more about LED functionality 8. Replace the Headpiece/Cable • • You should keep spare equipment on hand To order equipment contact us now 9.

Child is NOT responding to sound— *Note you have verified no response with a behavioral listening check. 10. Remove any materials that may be covering the microphone (i.e. Scarf, Hat, Headband) 11. Perform a test of the built in microphone using an empty program slot • Learn how 12. Try another audio input source • • Such as an Auxiliary Microphone or your Direct Connect Earhook interfaced with an audio device (i.e., CD/MP3 player).
Child is NOT responding to sound— *Note you have verified no response with a behavioral listening check. 13. Check for visible damage on the processor 14.
The Light (LED) on the Processor is Flashing…. 1.
Orange LED can mean the following: 1. PowerCel Status • • • • 3 to 4 quick flashes indicates the PowerCel is fully charged. 2 quick flashes indicates the PowerCel is sufficiently charged to power the system. 1 quick flash indicates the PowerCel is nearly depleted 0 change the PowerCel immediately 2. Low Battery Indicator • Steady Orange Light will emit when the PowerCel is near depletion 3.
Green LED can mean the following… 1. Microphone System Status • A green light will flash in response to loud sounds 2.
Red LED can mean the following… 1. Lock Status • Blinks at 1 second intervals indicating no lock with the implant 2. Intellink™ • Rapid blinks indicating wrong implant is connected 3.
Sound is intermittent: 1. Verify the Sound Processor is ON • Remember that sliding on the PowerCel turns the processor on 2. Check your connections including PowerCel, Earhook and Headpiece-Cable • Make sure they are secure 3.
Sound is intermittent— 4. Is the Headpiece positioned over the implant site? • Busy children can knock it off and may not be able to put it back in place. 5.

Headpiece will not stay on….. 1. CAUTION: adding too many magnets to the headpiece may cause physical discomfort and can potentially damage the skin around the implant site 2. How long has it been since surgery? Swelling is common for 1-2 months following surgery. 3. If significant time had elapsed, you may try the following: • • Back Use of an earmold, huggie or toupee tape will help keep the headpiece on as it will assist with the weight of the processor so it does not pull the headpiece off.
Child’s voice sounds muffled or distorted 1. 2. 3. 4. Is the processor turned on? Are the connections secure? Is the Volume Control in the 12 o’ Clock position? Verify the LED status • Learn how 5. Perform a behavioral listening check • Learn how 6. Perform test of the built-in Microphone • Learn how 7.

Performing a test of the built-in Microphone 1. Note: To assess the microphone, you will need to have an empty program slot on the processor. You will also need a Direct Connect system and an Audio Interface Cable 2. Using the Mic Tester Headphones supplied by Advanced Bionics attach to the Direct Connect 3. Set the program switch to an empty program slot (solid green light/LED should emit) 4. Connect a charged PowerCel 5.

How to Try another Audio Input Source 1. By connecting the direct connect system, audio interface cable and either an auxiliary microphone or portable listening device you can verify if the child can receive sound through another sound source. 2. Should the child receive sound with another audio source this verifies that the processor microphone is not functioning. 3. Contact the family and/or managing audiologist for further assistance.

Cleaning the Processor and PowerCel Contacts 1. To prevent intermittent operation of the Processor, contacts on both the PowerCel and Processor should be kept free from dirt, dust, perspiration or moisture. 2. Clean the contacts with a soft bristle brush (a hearing aid brush is best) at least once a month.
