Speech Processor Test Device
For your convenience you have been provided with a small grey Speech Processor Test
Device.
Fig. 45 Speech Processor Test Device
The Speech Processor Test Device is a simple, optional troubleshooting tool for MED‑EL
audio processors intended for use by cochlear implant users or other persons interact‑
ing with cochlear implant users (parents, audiologists, teachers, etc.).
The Speech Processor Test Device is not necessary for the function of your audio pro‑
cessor. It is simply intended to help detect most common audio processor problems like
defective coil cables, defective audio processor microphones, weak batteries or other
minor defects that might cause improper functioning of the audio processor.
If you suspect a malfunction of your audio processor, contact your CI centre or MED‑EL
or try the following procedure:
Switch on the audio processor and make sure that it is supplied with functioning
batteries. Place the coil underneath the Speech Processor Test Device (see Fig. 45). The
coil will position itself correctly due to magnetic attraction.
When speaking into the microphone, the red light on the Speech Processor Test Device
should icker in the rhythm of your voice. If the red light does not light up or stays on
constantly, try the following:
• Adjust the volume setting. By using the appropriate loudness setting, you should be
able to recognize the ickering of the red light in the rhythm of your voice.
• Change the batteries.
• Replace the existing coil cable with a substitute cable.
We recommend you try these steps independent of the use of your Speech Processor
Test Device. If these measures are not successful, immediately contact your CI centre or
Red indicator light
