Eagle 754 Service ToolkitOverviewService procedureSafetyHardware

Front-panel procedures (no software required)

Both procedures are documented in the OEM Operation & Service Manual.

USER PROGRAMS menu - read the PM counters and firmware version

  1. MODE switch to OFF.
  2. Press and hold MUTE/CANCEL and MANUAL BREATH/TRIGGER together.
  3. While holding both, turn MODE to A/C, SIMV, CPAP or CAL.
  4. The LCD enters USER PROGRAMS. The bottom line of every menu page shows:
  5. #### Hrs - cumulative hours of operation since the last preventive maintenance
  6. ### Dys - cumulative days since the last preventive maintenance
  7. Version #.## - firmware version

Write all three down before and after any reset; they are the proof that the reset worked.

Menu items: LCD backlight threshold (SAVE stores it), LCD contrast (SAVE stores it), trigger level sensitivity (temporary), set spontaneous flow (temporary), DEMONSTRATION MODE (training without disconnect alarm / proximal transducer; cancelled at power-off), TEST BACKUP VENTILATOR. Press the button next to EXIT to leave.

MODE = CAL - transducer zero

  1. Disconnect the patient circuit so the transducer (green) barb is at ambient pressure. Do not occlude anything.
  2. Turn MODE to CAL. The AMC shows the calibration-in-progress message; wait ~3 s until it reports complete. Turning the knob away early causes TRANSDUCER CALIBRATION ABORT.
  3. Turn MODE to the desired mode; the bar graph should sit at 0 cmH2O.

The firmware also re-zeroes automatically during SELF-CHECK and every 5 minutes (AUTO CAL). After an RTC reset the manual says the unit reboots with a Transducer Calibration alarm and must be put in CAL mode once.

DEMO mode for classroom use

USER PROGRAMS → DEMONSTRATION MODE gives A/C DEMO, SIMV DEMO and CPAP DEMO: settings, alarms and simulated waveforms without gas. It cancels at power-off. It does not clear the PM advisory, which is why the serial reset is needed.

What the front panel cannot do

There is no front-panel path to reset the PM clock. The manual's only reset is the PC program over RS-232 (section Computer Calibration, 4.0 "Initializing EEPROM / Resetting the Real Time Clock").
