Troubleshooting the

Harmony

What do you need in a kit to troubleshoot the

Harmony?

™ Spare headpiece and cable

™ Spare PowerCel

™ Access to meaning of LED displays (see next page).

™ Contact numbers

™ It might also be useful to have a Dri-Aid kit in case the processor gets wet.

™ A PowerCel charger will give you information as to whether the

PowerCel is charging correctly.

If there is a problem with the PowerCel charger try this link pages 49 and 50 http://www.bionicear.com/userfiles/File/Harmony_Processor_Us er_Guide_Rev_C.pdf

™ Listening earphones?

Advanced Bionics say that the LED will tell you anything you need to know. If the LED indicates no problem and the user is still complaining of problems, it is better to replace the processor.

However, listening headphones may be useful for listening to the signal through a radio hearing aid.

What if the processor gets wet?

Remove the PowerCel (battery) from the Harmony. Shake out any excess water. Place the Harmony and headpiece in the Dri-Aid Kit overnight. If no kit is available, leave to dry at room temperature.

Do not attempt to speed up the drying process by using a hairdryer or other equipment as this can cause further damage.

If you have no success, contact the implant centre.

What do the lights on the LED display mean?

As soon as you have connected the battery the LED will flash as follows:

Information on the batteries

3 or 4 quick orange blinks

No light

Battery fully charged

2 quick orange blinks Battery is sufficiently charged.

1 quick orange blink. Battery is nearly depleted.

Check the battery connection and change the battery if required

When the headpiece is on the child’s head, the green light (LED) should flicker in response to loud sounds, indicating the processor is functioning correctly. If it does not, refer to the table below.

Information on the microphone

Flickers green in response to loud sounds.

Steady green light

Empty program slot, change to another program

Information on lock (connection between the processor and implant)

Ensure headpiece retention is good. If still flashing change headpiece and cable. red continuously.

Ensure child is wearing their own processor not

Error condition, fully remove and reinsert battery.

What else could you try?

• Check the connections, including PowerCel, earhook and cables.

• Check for visible damage to components.

• Check the volume dial.

• Is the headpiece positioned over the implant site?

• Is the PowerCel charged and inserted properly? Try another

PowerCel.

• Are you using the appropriate program? Try another program.

• Check the Microphone/System status using the LED.

• Replace the Cable/Headpiece.

• Clean the battery contacts on both your PowerCel and Harmony

Processor.

• Remove any materials (hat, headband, scarf, etc.) that may be covering the microphone.

• You could try using an auxiliary microphone or the Direct

Connect earhook interfaced with an audio device (eg.CD/MP3 player) to check performance.

However

you will need to use a program that is designated to accept an external audio source. If there is no problem when using this alternative, place your processor in the carrying case/Dri-Aid overnight. If no sound is present the next day, contact your audiologist.

• Contact your audiologist for further troubleshooting if necessary
