Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Sound attenuation below spec
HighSymptoms: Ambient noise inside the booth exceeds the target, failed annual attenuation test.
Root cause: Worn door / window gaskets, a warped door, or loosened panel seams.
Ventilation fan noise or airflow loss
MediumSymptoms: Fan noise intrudes on testing, or the booth gets stuffy.
Root cause: Worn silenced-ventilation fan or a blocked baffle.
Interior light / signal fault
MediumSymptoms: Interior light out, talk-back or patient-response signal not working.
Root cause: Lamp / LED, the intercom, or the response-button wiring.
Jack-panel / feed-through fault
MediumSymptoms: Audiometer signal to the transducers drops or is noisy.
Root cause: Worn bulkhead jack panel or a broken feed-through connector.

Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Fails the attenuation check
- Measure ambient octave-band levels inside vs the target.
- Inspect and replace the door / window gaskets.
- Check the door closes flush and the latch draws it home.
- Re-torque loose panel seams.
- Re-run the attenuation test and document it.
Symptom: Fan noise or poor airflow
- Confirm the fan runs and airflow is present.
- Clean the ventilation baffles.
- Replace a noisy fan with the correct silenced unit.
- Verify interior noise with the fan running.
- Re-check the intercom and response signal.
