Cochlear SPrint Sound Processor Programming manual
Troubleshooting the Sprint
What do you need in a kit to troubleshoot the Sprint?
Batteries (2xAA)
transmitting cable
headset cable
Signal check (part no. Z22502)
lapel microphone
Monitor earphones for the sprint (part no. Z43139)
CL clinic contact numbers
Guide to codes on LCD
Check:
The low battery symbol is not showing.
The correct coil is properly in place. (Coil should have ‘S’ or ‘L’
embossed on to it.)
Both the headset cable and transmitting cable are connected
properly.
The cables are not broken or cracked.
When the processor is working correctly 5 – 8
segments will show on the segment meter in
response to speech. The red indicator light will also
flash.
If the indicator light and segment meter do not respond to
sound:
•Change all batteries ensuring that they are in the correct way.
•Ensure that battery contacts are clean. Rub the terminals with
an eraser and clean with alcohol wipes if possible.
Check the microphone
Leave the processor on.
Plug the listening headphones into the
socket at the top of the processor. It is the
smaller of the two sockets under the flap.
You can listen to the quality of sound being
picked up by the microphone (this is not the
same as the signal the CI user is receiving).
Adjust the microphone sensitivity and
volume settings.
If the sound you hear is distorted at normal
sensitivity (12), return the microphone to the CI centre.
Check the coil
Check the cables are correctly connected.
A = headset cable with orange connector in bottom socket. B =
transmitting cable in top socket.
Check the coil using the signal check
.
Turn on the processor as normal. The light on the
signal check should light up when placed over the
coil on the child’s head.
If the red light does not come on:
First change headset cable. Speak into the microphone. Check the
signal.
If the red light still does not come on:
Change transmitting cable. Speak into the microphone. Check the
signal.
If the red light still does not come on:
Plug the lapel microphone into the
accessory input socket. Speak into the
lapel microphone.
If the light goes on:
There is something wrong with the microphone. Return it to the CI
centre.
Or you can check if the processor is transmitting sounds to the
implant by placing the coil over the back of the Sprint
.
Turn the processor on. If it is working
correctly this symbol should appear in the
LCD: If it does not the transmitting
coil or transmitting cable need
to be changed.
Check the headset.
Turn on the processor and set microphone
sensitivity to 10 or 12.
Put coil in place over implant.
Speak normally into the microphone.
If the segment meter moves, there is no problem
with the connection between the processor and the
headpiece.
If the segment meter does not move:
Change the headset cable.
If the segment meter still does not move:
Change the transmitting cable.
If the segment meter still does not move:
Plug the lapel microphone into the accessory input socket. Speak
into the lapel microphone.
If the segment meter still does not move:
Contact your CI centre.
If the segment meter does move: There is a problem with the
original microphone.
Program is faulty. Turn processor on and off again. A
new program will be selected automatically. If symbols
remain, refer to CI centre.
If there is intermittent buzzing or distorted sound
This may be due to interference from electromagnetic fields from an
electronic device. Look for a possible source eg mobile phone tower,
mobile phones, radio transmission towers or computer screens. Move
away from them. If the problem persists, consult the clinic.
If speech is unclear, soft or too noisy:
Check headset.
Check segment meter by talking into the microphone. If there are
less than five segments showing, the speech may be too soft. Try
turning up the sensitivity or ask the speaker to speak up!
If the segment meter shows more than eight segments, try to reduce
noise in the environment. Decrease the sensitivity. It may also be
necessary to change the volume.
If the processor gets wet
If the processor is dropped in water, remove battery compartment
and return to implant centre.
If it is damp, remove the battery compartment and put it in the
pouch supplied with the dry pack. If you need more chemicals for
the dry pack, they are available from pharmacies. Leave it in the
pouch overnight and the dry pack will absorb the excess moisture.
