The Cochlear Experience
Troubleshooting: ESPrit 3G
Each day, before you turn the processor on, check that the cable is properly connected to the processor and not broken or cracked;
mode setting (at the base of the processor) is the setting you want; the program location, sensitivity or volume control level is as recommended by your clinician; and the transmitting coil is in place on your head
Each night, after you turn the processor off clean the microphone area, using the puffer ane store the speech processor overnight with the drying aid. Moisture or humidity may cause cut-outs or failures.
Follow these steps
If you cannot hear any sound from your processor, take the following steps:
1. Reset the speech processor: switch it Off for about five seconds, and then On again.
2. Use the Signal Check to check the transmitting coil. If the Signal Check lights up, the coil is functioning. If it does not, replace the transmitting coil and cable.
3. Replace ALL of the batteries with fresh, High Power Zinc Air batteries
4. Remove the battery seals at least one minute before inserting them.
5. Occasionally clean the battery contacts with the cleaning brush
6. Ask a hearing person to use monitor earphones to check the microphone on the ESPrit™ 3G
7. Attach and use the lapel microphone. An improvement in sound quality indicates that the ESPrit 3G microphone may be faulty or may need drying out with the drying aid. Contact your clinic if drying out does not solve the problem.
8. Try moving away from any electronic device that may be causing interference.
9. Ensure mode switch “TWM” is in the correct position.
Note: Ensure you are using the correct cable/coil. The Nucleus® 24 cable connector is yellow. The Nucleus® 22 cable connector is green.
After each step, check if there is any sound. If there is still no sound, contact your clinician, cochlear implant centre or your nearest Cochlear office.
