Introduction Scope This manual and the equipment it describes are for use only by qualified Biomedical Service Personnel. It is intended only as a guide for technical maintenance of the H ™ Generator 300 System. ARMONIC This manual is intended to be a companion to the H ™...
Chapter 1 - Warnings, Precautions and Notes Warnings and Precautions • This equipment, in conjunction with the accessories, is intended to produce high-frequency mechanical energy which enables hemostatic cutting and/or coagulation of soft tissue. • Safe and effective ultrasonic surgery is dependent not only upon equipment design, but also, to a large extent, upon factors under control of the operator.
Service Manual • Do not connect the The H ™ Generator 300 System to an ungrounded outlet. Grounding ARMONIC reliability can only be achieved when this equipment is connected to a hospital-grade receptacle. • Spilling or spraying fluids on or into the generator or immersing the generator may result in damage to the generator and risk of shock or fire hazard.
Chapter 2 - General Description System Description The H ™ Generator 300 System utilizes ultrasonic energy to enable hemostatic cutting and/or ARMONIC coagulation of soft tissue. The system consists of an ultrasonic generator, a foot switch, an optional hand switching adaptor, a hand piece, and a variety of open and minimally invasive instruments. Note: Throughout this manual “instrument(s)”...
Chapter 3 - Theory of Operation The H ™ Generator 300 System consists of the following components: Generator (GEN04), ARMONIC hand piece, instruments, foot switch, and hand switching adaptor (if used). The generator produces an electric signal, which is transmitted via a coaxial cable to the hand piece, which then converts the electrical signal into ultrasonic, mechanical motion.

Chapter 4 - System Setup Turn the generator power switch on and observe the power-up sequence. During power-up, the following indicators on the front panel will briefly illuminate: • READY, STANDBY, MIN, MAX, TEST, ATTENTION, HAND ACTIVATION The system will run its start-up sequence and display the software version. An audible tone will sound during the initiation sequence.
Chapter 5 - Operation Controls, Indicators, and Connections Fig. 5-1 Front Panel When this indicator is green, the system is ready for activation. READY Note: In the Ready mode, for self-diagnostic purposes, the system sends a low-amplitude signal to the blade, causing the blade to vibrate slightly. This vibration does not pose a risk to the user.

Service Manual HAND PIECE This receptacle is used to connect the hand piece to the generator. RECEPTACLE HAND ACTIVATION When the indicator is green, hand activation on the hand switching adaptor is enabled. To disable the Hand Activation mode, depress the button. Upon power-up, the system defaults to Hand Activation mode disabled.
Chapter 5 - Operation Screen Descriptions Power-Up Screen Below is an example of the Software Version displayed during power-up. Fig. 5-3 Power-Up Screen Tone Selection Screen Refer to Chapter 15 – Adjustments for descriptions of the Tone Selection Screens. User-Initiated and Pre-Activation Test Screens The generator will cycle between the following two screens, displaying each screen briefly, for the duration of the time that the system is in the User-Initiated Test state and Pre-Activation Test state.

Service Manual The following are all possible screens for the Standby, Ready, and Run states in Normal mode. The number on the left indicates the power level for MIN activation (1 to 5), and the number on the right is the power level for MAX activation.
Chapter 5 - Operation System Operation For an understanding of system operation, refer to the H ™ Generator 300 System Operator’s ARMONIC Manual for instructions and specifications for use of the H ™ Generator 300 System, Foot Switch, ARMONIC and Cart. Refer to package inserts provided separately for information about the Hand Piece, Hand Switching Adaptor, Adaptors, Test Tip and Instruments prior to using the system.
Service Manual System Shutdown Turn the generator power switch off and remove power cord from outlet. Disconnect the hand piece, instrument, and adaptor or hand switching adaptor (if used) and process them as indicated in their respective package inserts. Clean the generator and cart and disinfect the foot switch(es) following hospital protocol (for recommendations, refer to Chapter 6 –...
Chapter 6 - Cleaning and Disinfection Generator and Cart Cleaning Clean generator and cart following hospital protocol. Before cleaning, turn the generator main power off and unplug the power cord from the grounded electrical outlet. Warning: Spilling or spraying fluids on or into the generator or immersing the generator may result in damage to the generator and risk of shock or fire hazard.
Chapter 7 - Safety and Function Testing Test the hand piece, generator, and foot switch for safety and function according to hospital protocol. Refer to individual package inserts for safety and function testing for other multi-patient use components. Safety Test Generator: A qualified hospital technician should perform a leakage current test.
Chapter 8 - Generator Output Check Procedure for Checking the output of GEN300 Generators Perform the functional test sequence of steps contained in the service manual, Chapter 7 – Safety and Function Testing (page 23). Then check the generator’s current output: Power the generator off.

Page 35
Chapter 9 - High-Level System Troubleshooting Note: As the hand piece ages, the generator performs measurements and updates a key hand piece parameter. This function is performed when the internal temperature of the hand piece is stable at room temperature. Certain usage patterns may prevent this update from occurring and subsequently make the hand piece diagnostics more sensitive to temperature.
