What to do if my OTIS GEN II OI-6000 shows 'F14 Check Radio'?

  Wendy BowmanAug 3, 2025
  If your OTIS Other displays the error 'F14 Check Radio', it indicates that the sensor assembly has lost communication with the Primary Monitor. This can occur if the Network ID is incorrectly configured, the sensor assembly is obstructed or too far from the Primary Monitor, or the radio module is not working. First, verify that the Network ID on the sensor assembly matches the Primary Monitor Network ID. If the issue persists, move the sensor assembly away from any obstructions or consider using a high gain antenna. As a last resort, replace the sensor radio module.

  Joshua CurtisAug 9, 2025
  If your OTIS Other displays 'F5 Try to Null Again', it means the unit didn't null correctly. This could be due to the presence of gas, a sensor error, or a sensor interface board error. Try re-nulling the device in clear air. If the problem continues, consider replacing the sensor element or the sensor interface board.

What should I do if my OTIS Other displays 'F6 Try to Calibrate Again'?
- B
  Beverly WardAug 15, 2025
  If you see 'F6 Try to Calibrate Again' on your OTIS Other, it indicates that the unit did not calibrate correctly because of the absence of gas, a sensor error, or a sensor interface board error. Recalibrate the sensor element and make sure gas is present during calibration. If the issue is not resolved, replace the sensor element, or replace the sensor interface board.
