PROBLEM
POSSIBLE CAUSE
TEST / RESOLUTION
Painful fit
Speaker unit is
incorrectly inserted
into the ear
Insert correctly and re-train the recipient in correct
insertion.
Hybrid system is not
properly fitted
1. Check areas of the outer ear where the sound
processor sits for sore spots or friction marks.
2. 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.
Wax buildup in the
outer ear canal
Check for sore spots using an otoscope – these are
usually caused by wax buildup. Refer the patient to a
medical practitioner to have their ear canal cleaned.
Output lower

Microphone cover

Change microphone cover.
Loose Hybrid
receiver connection

and replace any damaged parts.
Incorrect program
Perform a listening test. Use Acoustic Test Box or
Hearing Instrument Test Box if available and cross
check against target curve in the Custom Sound
software.
Hybrid receiver is
broken
Check the Hybrid receiver using a listening test, and
replace it if required.
If the test is not conclusive, reproduce the OSPL90
curve from the Data Sheet and check against the
outlined limits.
