Follow the dangers, warnings and cautions given below when handling and servicing this electrosurgical unit. This information is to be supplemented by the dangers, warnings and cautions given in each chapter.

User-related error prevention

WARNING Improper use

The safety and effectiveness of electrosurgical interventions depend not only on the design of the equipment used, but also to a major extent on factors which are under the control of the user. It is therefore extremely important to read, understand and follow the instructions supplied with the electrosurgical generator and the accessories in order to ensure safety and effectiveness.

Always use the electrosurgical generator as outlined in this maintenance manual. Improper use will not only impede functions and prevent optimum performance, but may cause equipment damage and / or complications. Before each use, always inspect the equipment as outlined in this maintenance manual.

WARNING Annual safety checks / Inspection

The electrosurgical generator and the footswitch must undergo a safety check in yearly intervals in accordance with the national statutory regulations (refer to chapter 7 “Inspection”).

Environmental conditions

CAUTION Interference of the unit with other equipment

Be sure that this electrosurgical unit is not used adjacent to or stacked with other equipment (other than the components of this electrosurgical unit or system) to avoid electromagnetic interference.

Before use, thoroughly confirm the compatibility of all equipment.

To ensure electrical safety, the electrosurgical unit should not be used in conjunction with:

•Electrical equipment whose safety against leakage current is not guaranteed.

•Electrosurgical equipment whose safety in combined use is not guaranteed.

The electrosurgical generator complies with the electromagnetic compatibility (EMC) standard. Nevertheless, when the electrosurgical generator is active it may disturb neighboring electronic equipment. If an auxiliary computer system is in use together with the electrosurgical generator and endoscopic imaging techniques, the image on the monitor might freeze or blackout. Follow the instructions in “Electromagnetic Compatibility (EMC) information” in the Appendix of the instruction for use regarding electromagnetic ambient conditions.

Never loop the cords (active cord, bipolar cord, neutral electrode cord) or bundle cords together with cords belonging to other medical equipment. The high frequency signals or spark discharge noise generated by the unit may interfere with the operation of other medical equipment.

Do not use the electrosurgical unit in a location exposed to strong electromagnetic radiation (microwave or short-wave medical treatment equipment, Magnetic Resonance Imaging, radio or mobile phone equipment). Electrosurgical unit malfunction can occur.

CAUTION Unsuitable temperature and humidity

The electrosurgical generator should only be used under the conditions as described in chapter 1-3 (Limitations). Use under other conditions may impede normal performance and / or result in equipment damage.

Accessories

WARNING Mechanical stress

Do not apply excessive bending, straining, or squeezing force to any cords. It may cause malfunction.

CAUTION Non-compatible accessories and accessory damage

The electrosurgical generator shall only be used with compatible accessories. When connecting accessories (cords, electrodes, HF instruments) avoid output settings where the maximum output voltage of the electrosurgical generator may exceed the rated accessory voltage (refer to “Mode characteristics”, “Output characteristics” in the Appendix of the instruction for use, and the instruction manual of the accessory). For a list of compatible neutral electrodes, refer to “Specifications” in the Appendix of the instruction for use.

Before use, the electrosurgical unit and accessories must be examined for damage. All communication cables and its plugs must be free of scratches and cracks. Cables and accessories with damaged insulation or connections must not be used.

Electric shock

WARNING Grounding failure

To prevent the risk of electric shock, the housing of the electrosurgical unit must be grounded. Always connect the power cord plug to a properly grounded wall outlet. Do not use a 3-pin / 2-pin adapter, as it can impair safe operation of the unit.

WARNING User shock

To prevent user shock, malfunction and damage of the electrosurgical unit, keep liquids away from all electrical equipment.

When taking measurements or troubleshooting of the electrosurgical unit, take appropriate precautions, such as using isolated tools and equipment, using the “one hand rule,” etc.

CAUTION Injury during servicing

When the housing is opened, there is a danger of electric shock. The unit must only be serviced by authorized technicians.

Burns

WARNING User

The maximum output voltage characteristics of the electrosurgical generator are shown in the diagrams in “Output characteristics” in the Appendix of the instruction for use. When setting the power level, first set it to a low level and increase it gradually. If the output is initially set to a high level, the electrode’s insulation may be damaged and cause user and / or patient burns. However, certain modes may present an unacceptable risk at low output power settings. For example, with the PulseCut fast mode or PulseCut slow mode, the risk of an excessive thermal effect rises if the output power setting is too low. Therefore, it is recommended that you perform basic testing before using the electrosurgical generator. If the instruction manual of the HF instrument to be used stipulate a rated voltage, the output should be set so that it does not exceed that voltage.

High frequency, high voltage signals that can cause severe burns are present in the monopolar / bipolar sockets described in this maintenance manual. Take appropriate precautions when testing and troubleshooting this area of the electrosurgical unit.

ESG-400

2 Features

The ESG-400 is a reusable, non-sterile electrosurgical generator with different monoand bipolar cutting and coagulation modes. The maximum output power is 320 W.

On the front side it features a touch screen display that displays the connection status of accessories and peripherals connected to the electrosurgical generator. It is also used to show and modify the output settings (e.g. mode, output power, effect) as well as to control other functions (e.g. save settings).

In addition the ESG-400 has a bipolar socket, two monopolar sockets, a neutral electrode socket, and a universal socket to connect applicators with instrument recognition. The power switch turns the generator on and off.

Two contact quality indicators (one for split and one for non-split electrodes) are green illuminated if neutral electrodes are correctly connected. Three additional push buttons allow recalling a previously saved setting (Select Procedure), to assign the footswitches to specific output sockets (Footswitch), and to control several other functions (Menu), e.g. select language, touch tone control, output volume, or brightness.

On the rear panel the volume control, a ventilation hole, the equipotential bonding point, the AC power socket, and two footswitch sockets can be found. Furthermore, for the connection of peripheral equipment 26-pin plugs respectively 14-pin plugs can be connected to the LINK-IN or to the LINK-OUT socket.

On the bottom panel, a docking socket is featured. It can be used to connect the ESG-400 directly to the USG-400 and upcoming devices. The ESG-400 is compatible with the new USG-400 ultrasonic generator to enable the use of combined (US + HF) instruments.
