Test / resolution
Check batteries and replace/recharge if necessary.
1. Replace the dome (with its built-in wax filter).
2. Check the wax filter on the speaker unit and
replace if necessary.
Educate the recipient to do this regularly.
Replace the Hybrid receiver.
1. Perform a listening test using a Stetoclip. If this
shows a problem, send the sound processor for
repair.
2. Perform a listening test using a Cochlear Monitor
Earphone Adaptor and earphones. If this shows a
problem, send the sound processor for repair.
1. Check the Hybrid receiver cable length. If it is too
long, the cable will not sit nicely against the ear
and the speaker unit may sit too low in the ear
canal. If it is too short, the dome may keep
falling out. Adjust so it sits snugly and without
tension. See Shape the Hybrid receiver cable on
page 22.
2. If it is still not correct, change to a different
length Hybrid receiver.
Change to a dome with less venting.
Change to a bigger dome.
Change to the correct Hybrid receiver.
