Frequency: 55.5 kHz (output). Power Requirement: 115 VAC, 60 Hz, 2 Amps, 230 Watts max. Fusing: Two, 3 AG Slow Blow 1⁄4” x 1 1⁄4”, 2 Amps, located in the power entry module. Three, internal, 5 mm x 20 mm Slow Blow, 1@ 1 Amp, 1 @ 0.25 Amps, and 1 @ 1.6 Amps. Air Pressure: 6 psi Max. Air Flow: Approximately 20 liters per minute. Ventilation: At least 2” in rear of the unit and the bottom vents should not be obstructed.
Key tips
- ·Never defeat or bypass a return-electrode monitoring (REM) alarm to finish a case - it's a direct burn risk.
- ·Verify OR table battery backup - a table that loses power mid-procedure is a real, documented incident type.
- ·Track surgical light lamp-hours rather than waiting for failure - a sudden failure mid-case is avoidable.
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.
No or low RF output / high-impedance cut-out
HighSymptoms: No cut / coag effect, "high impedance" or output-error message, output shuts down.
Root cause: Poor electrode contact or a dry field, a damaged handpiece / cable, a return-electrode (REM/NESSY) fault, or an output-stage fault.
Return-electrode (patient-plate) contact-quality alarm
MediumSymptoms: REM / NESSY / plate alarm, monopolar output inhibited.
Root cause: Poorly applied or dried split dispersive pad, a pad-cable fault, or the contact-quality-monitor circuit.
Bipolar / vessel-sealing output fault
MediumSymptoms: Bipolar or sealing output weak, seal cycle will not complete, instrument not recognised.
Root cause: Bipolar cable / instrument fault or the sealing output stage.
Fails calibration / output drifts after a repair
MediumSymptoms: Output power or the REM circuit outside tolerance on the analyser.
Root cause: Output board or REM circuit needs recalibration - anti-static handling required.
Footswitch / handswitch fault
MediumSymptoms: Output will not activate from the pedal or the handpiece.
Root cause: Footswitch or handswitch / cable fault.
Touchscreen / display / boot fault
LowSymptoms: Unresponsive touchscreen, will not power on or boot, fan / thermal alarm.
Root cause: Display, power supply, control board, or a cooling-fan fault.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Pre-case functional check
- ·Electrosurgical return-electrode cable inspection
- ·Table hydraulic / mechanical inspection
- ·Annual electrical safety test and full PM
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 or low RF output / high impedance
- Confirm good electrode-tissue contact and an adequately wetted field.
- Inspect the handpiece / instrument and cable for damage; substitute known-good.
- Check the split dispersive pad is well applied with full skin contact and a good cable.
- Verify output into a resistive test load with an electrosurgical analyser.
- Replace the output board and recalibrate if output is confirmed absent (anti-static workplace).
Symptom: Return-electrode / plate alarm
- Re-apply a fresh split dispersive pad with full skin contact over well-perfused muscle.
- Check the pad cable and connector.
- Try a known-good pad.
- Run the contact-quality-monitor calibration if it still alarms with a good pad.
- Do calibration on a non-conductive surface.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
An internal component may be cracked and become lodged behind the energy button potentially resulting in continuous activation of the device, may result in burns
- RECALL
The devices may have been assembled with an internal component that may cause continuous or inadvertent activation of the device.
- RECALL
Complaints of holes in Tyvek which can compromise the sterile barrier provided by the packaging.
- RECALL
Ethicon Endo-Surgery initiated a voluntary recall due to some lot numbers of the HARMONIC Hand Piece (HP054) and the HARMONIC Blue Hand Piece (HPBLUE), which impacts their compatibility with the HARMONIC Generator 300 (GEN04). The problem occurs after successful set up and initial use of HARMONIC Hand Pieces (HP054 and HPBLUE) with the Generator 300 (GEN04). The procedure is interrupted when
