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: No output on a channel
- Fit fresh electrodes and confirm good skin contact.
- Substitute a known-good lead wire.
- Test the same channel with a load resistor / tester if available.
- Try the module in another XT base to isolate module vs base.
- If output is still absent, replace the module.
Symptom: Error 200-399
- Note the exact code.
- Power-cycle the therapy system.
- Follow any on-screen instruction for user-definable errors (100-range).
- For 200-399, the module needs technical assistance - remove from service.
- Contact Chattanooga / DJO service with the code.
