3 seconds, and then ‘On’.
•
Confirm that the student is using the recommended mode setting.
•
Confirm that the child is using the recommended program setting.
•
Confirm that the rotary wheel is set at the recommended setting.
If the child reports no sound from the processor and the above inspection is

Troubleshooting Steps
STEP 1: Check/change the batteries
•
Switch the ESPrit 3G off and
open the battery cover.
•
Check that the batteries
are inserted correctly with
the positive (flat) side up.
•
Replace all batteries using
the 675 PowerOne HP
zinc air batteries in the kit.
STEP 2: Check whether the transmitting
coil/cable is sending a signal across the skin
•
Check that the transmitting cable
connection is plugged in correctly.
— Cable/coil N24 = yellow, N22 = green
•
Use the signal check from the
troubleshooting kit.
•
Turn ‘ON’ the sound processor and set
at the student’s normal settings.
•
Hold the transmitting coil in one hand or place it on the child’s head.
•
Hold the signal check over the transmitting coil.
Red light should illuminate.
•
If it doesn’t light up, there is no coil transmission.
•
Replace the transmitting coil.
•
Place the coil on the child’s head or in your hand and turn
the sound processor ‘ON’.
•
Try again using the signal check.
•
If still no coil transmission, check the processor
microphone [See Step 3].
