Introduction

This troubleshooting kit was developed by Cochlear™Americas speciﬁcally for

individuals who work with children with cochlear implants in school settings.

It is intended to help identify and remedy simple problems with a child’s sound

processor and minimize the amount of time that a child is without auditory

stimulation. It is important that this kit only be used for a child implanted with

a Nucleus®cochlear implant system.

We currently support six speech processors in the Nucleus family. They include:

Each processor requires somewhat different troubleshooting procedures. Hence

the contents of this manual are separated according to the various models of

sound processors.

It is recommended that at least one person at the child’s school become

familiar with this kit and, most importantly, understand how to use it relative to

the applicable sound processor.

For information on working with a child with a Nucleus cochlear implant,

please refer to the booklet,“A Teacher’s Guide to the Nucleus®Cochlear

Implant System”. To order your free copy, please contact

•24” HS8 headset cable – beige

•Earhook, large

•Signal check

•31” lapel microphone & clip for the SPrint

•Monitor earphones for the SPrint

Before doing step-by-step troubleshooting, conduct a maintenance

check of the equipment by visually inspecting it.

Maintenance Check

Conﬁrm:

•The headset and transmitting cable are properly connected.

•The cables are not broken or cracked.

•The correct transmitting coil is in place on the student’s

head (should see an “S” or “L” embossed on the coil).

Also check the following:

•Conﬁrm that the SPrint is ‘ON’.

•Check that the segment meter on the LCD panel

responds within the normal range when speaking

into the microphone (with sensitivity set on at least 10).

•Conﬁrm that the child is using the recommended

program setting(s).

•Check that the red indicator light at the top of

the sound processor is responding to sound input.

If the child reports no sound from the processor and the above inspection

is good, take the following steps:

Troubleshooting Steps

STEP 1: Check/change the batteries

•Look at the LCD panel on the SPrint.The low

battery symbol will appear if the batteries are

inserted wrong or if the batteries need replacing.

—Conﬁrm the batteries are inserted correctly

into the battery pack.

—Replace both batteries using the alkaline

disposable AA batteries in the kit.

STEP 2: Check if the sound processor is transmitting

sound to the cochlear implant

•Turn on the sound processor and set at the

child’s “normal” settings.

•Place the transmitting coil over

the back of the SPrint.

•Look at the LCD display on the

front. If the sound processor is

transmitting a signal, the LCD

displays the radio frequency

(RF) test coil symbol.

•If no RF transmission, check the

transmitting coil [See STEP 3].

Alternatively, use the signal check to check the transmitting coil.

•Turn on the sound processor and

set at the child’s “normal” settings.

•Place the signal check over the

transmitting coil, if the signal

check lights up the coil is

functioning. If it does not,

replace the transmitting coil,

transmitting cable or headset.

STEP 3: Check the headset components (cables, microphone)

Cables:

•Check that the cable connections are plugged in correctly.

•Hold the microphone case with one hand and

put your thumbnail in the slot on the microphone

cover. Remove the microphone cover by pulling

it away from the microphone case.

•Plug the orange connector on the headset

cable (A) into the orange socket at the bottom

of the microphone case.

•Plug the transmitting cable (B) into the socket

at the top of the microphone case.

•Place the coil in your hand.

•Turn on the SPrint and set microphone

sensitivity to 10.

•Speak into the microphone and check if the

segment meter responds to speech.

•If no response, change each cable sequentially using

the cables from the kit.

—Check the segment meter after

each cable change to determine whether

it responds to speech.

•If the segment meter still does not respond,

go to the next step to check the

ear-level microphone.

Microphone:

To ensure the ear-level microphone is working, use the lapel microphone

from the kit.

•Turn off the sound processor and remove

from the child’s head.

•Insert the lapel microphone connector into

the top of the SPrint processor.

•Place the transmitting coil on the child’s head

or in your hand, turn on the sound processor

and set at the child’s “normal” settings.

•Speak into the microphone and check if the

segment meter responds to speech.

•If the segment meter responds, the

ear-level microphone is faulty and

the lapel microphone can be used

as a substitute until the child’s

headset microphone can be replaced.

•Inform the parent that a replacement

microphone is required.

Note: If the child needs to use the lapel microphone, clip the lapel microphone onto

the child’s clothing where it is least likely to be jostled, obstructed or contacted

(clothes, food or ﬁngers brushing over the microphone will generate sounds).

If you have reached the end of these instructions, and have not been able to

address or identify the issue, please contact:
