Ear canal volume Explanation
Blue
The ear canal volume is too large for the test to begin. The probe is not in the ear or
there is a large leak.
Green
The ear canal volume is in the target range for testing. The test will begin automatically
if the probe fit is stable.
Orange
The ear canal volume is too small for the test begin. The eartip may be pressed against
the ear canal wall or the probe tube may be completely clogged.
Troubleshoot the AutoStart probe check
Appropriate adjustments of the eartip position and size selection should be made until
the indicator falls within the green area and remains stable. If the test will not progress
past the AutoStart probe check stage:
1. Change the probe tube.
2. Confirm that the probe connector is fully seated in the socket.
3. Run the AutoStart probe check again.
