Phonak Nathos Troubleshooting And Maintenance

SOUND PATH BLOCKED
When the sound path is blocked, the hearing aid is working and
sound is coming in and being amplied, but it is not coming out.
Usually the blockage is in the tubing, dome or earmould.
How to check: turn the aid on and (if you can) detach tubing
from the body of the aid – if the blockage is in the tubing, you
will hear the aid working.
