Startup Troubleshooting

Error Screen	Problem	Solution
	Sensor Error The sensor failed during the self-test.	Calibrate the sensor(s). Refer to Calibration. Reactivate the detector. If error displays again, replace the sensor. Refer to Replacing a Sensor or Sensor Filter.
	Calibration Overdue Displays when calibration is overdue. If the Force Calibration When Overdue option is enabled, the sensor(s) must be calibrated to enter normal operation.	Press to continue and calibrate the sensor(s) immediately. Refer to Calibration. If the IR Lock enabled screen displays, the MicroDock II station or the IR Link with Fleet Manager II must be used to calibrate.
	Forced Calibratione If Force Calibration When Overdue is enabled, the sensors must be calibrated to enter normal operation.	Press and hold to calibrate the sensors, or press and release to deactivate the detector. Refer to Calibration. If the IR Lock enabled screen displays, an IR device must be used to calibrate.
	IR Lock Enabled If the IR Lock screen displays, an IR device is required to calibrate the sensors.	Perform calibration using the IR Link with Fleet Manager II software, or insert the detector into the MicroDock II station. Refer to Cal Lock (Calibration IR Lock) in User Options and Calibration.
	Bump Test Fail A bump test has just been performed. The detector is prompting for another bump test because a sensor(s) has failed.	Perform another Bump Test. Ensure the cylinder is not empty and that the cylinder is not past the expiry date. Ensure the regulator is fully opened to apply gas. If Bump Check Today displays again, calibrate the sensors. Refer to Calibration. If the calibration is unsuccessful, refer to Replacing a Sensor or Sensor Filter.
	Sensor Fail A sensor has failed during the startup self-test.	Perform a Bump Test and reactivate the detector. If the sensor fails again, perform Calibration. Reactivate the detector again. If the sensor still does not pass, refer to Replacing a Sensor or Sensor Filter.
