Microphone Verification
Microphone verification is necessary to assure the microphones and speaker are operating properly. A microphone
verification is required each time the software is started. Re-verification is required after four (4) hours of use or after fifty (50)
fit-test sessions, whichever comes first.
1) Slide the right (red) and left (blue) microphones into the speaker clips as illustrated on the software screen.
2) Click the Start Verification button.
– If the microphones are functioning correctly, a green check mark will appear. Click Continue to Testing to
proceed.
– If verification does not pass, a red X will appear. Disconnect and reconnect the microphones and press Try Again.
