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.
