SAFETY PRECAUTIONS WHEN REPAIRING THE GENERATOR Before servicing the Bovie® DERM 101/102 High Frequency Desiccator it is important that you read, understand, and follow the instructions supplied with it. Also, be familiar with any other equipment used to install, test, adjust, or repair this generator.

General Warnings, Cautions, and Notices WARNING The instrument receptacles on this generator are designed to accept only one instrument at a time. Do not attempt to connect more than one instrument at a time into a given receptacle. Doing so will cause simultaneous activation of the instruments. To avoid risk of electric shock, this equipment must only be connected to a supply mains with protective earth.

CAUTIONS Do not stack equipment on top of the generator or place the generator on top of electrical equipment. These configurations are unstable and/or do not allow adequate cooling. Unit is designed to be wall mounted or mounted on a mobile stand. Provide as much distance as possible between the electrosurgical generator and other electronic equipment (such as monitors). An activated electrosurgical generator may cause electrical interference with them. Do not turn the activation tone down to an inaudible level. The activation tone alerts the surgical team when an accessory is active. No modification of this equipment is allowed.

NOTICE Connect the power cord to a wall receptacle having the correct voltage. Otherwise, product damage may result.

Active Accessories WARNINGS Shock Hazard – Do not connect wet accessories to the generator. Shock Hazard – Ensure that all accessories and adapters are correctly connected and that no metal is exposed. Associated equipment and active accessories should be selected that have a rated accessory voltage equal to or greater than the maximum output voltage. Accessories must be connected to the proper receptacle type. In particular, bipolar accessories must be connected to the Bipolar Instrument output jack only. Improper connection may result in inadvertent generator activation.

CAUTIONS Accessories must be connected to the proper receptacle type. In particular, bipolar accessories must be connected to the Bipolar Instrument receptacle only. Improper connection may result in inadvertent generator activation. Examine all accessories and connections to the electrosurgical generator before use. Ensure that the accessories function as intended. Improper connection may result in arcs, sparks, accessory malfunction, or unintended surgical effects. Refer to the accessories instructions for use for more detailed instructions. Set power levels to the lowest setting before testing an accessory.

NOTICES To avoid incompatibility and unsafe operation, we recommend using only Bovie®/Aaron® accessories. During bipolar electrosurgery, do not activate the generator until the forceps have made contact with the patient. Product damage may occur.

Fire / Explosion Hazards WARNINGS Explosion Hazard – Do not install the generator in the presence of flammable anesthetics, gases, liquids, or objects. Fire Hazard – Do not place active accessories near or in contact with flammable materials (such as gauze or surgical drapes). Electrosurgical accessories that are activated or hot from use can cause a fire. Use a holster to hold electrosurgical accessories safely away from personnel and flammable materials. Fire Hazard – Do not use extension cords. Fire Hazard – For continued protection against fire hazard, replace fuses only with fuses of the same type and rating as the original fuse.

Generator Electric Shock Hazards WARNINGS Connect the generator power cord to a properly grounded receptacle. Do not use power plug adapters. To avoid risk of electric shock, this equipment must only be connected to a supply mains with protective earth. Connect the power cord to a properly polarized and grounded power source with the frequency and voltage characteristics that match those listed on the back of the unit. Disconnect power cord from power source to isolate the internal circuits from the supply mains. Do not connect a wet power cord to the generator or to the wall receptacle. To allow stored energy to dissipate after power is disconnected (caps discharge) wait at least five minutes before replacing parts. Always turn off and unplug the generator before cleaning. Do not touch any exposed wiring or conductive surfaces while the generator is disassembled and energized. Never wear a grounding strap when working on an energized generator. When taking troubleshooting measurements use appropriate precautions such as using isolated tools and equipment, using the “one hand rule,” etc. Potentially lethal AC and DC voltages are present in the AC line circuitry, high voltage DC circuitry, and associated mounting and heat sink hardware described in this manual. These potentials are not isolated from the AC line. Take appropriate precautions when testing and troubleshooting this area of the generator. High frequency, high voltage signals that can cause severe burns are present in the RF output stage and in the associated mounting and heat sink hardware. Take appropriate precautions when testing and troubleshooting this area of the generator.

Servicing CAUTIONS Read all warnings, cautions, and instructions provided with this generator before servicing. The generator contains electrostatic-sensitive components. When repairing the generator, work at a static-control workstation. Wear a grounding strap when handling electrostatic-sensitive components, except when working on an energized generator. Handle circuit boards by their nonconductive edges. Use an anti-static container for transport of electrostatic-sensitive components and circuit boards.

Cleaning NOTICE Do not clean the generator with abrasive cleaning or disinfectant compounds, solvents, or other materials that could scratch the panels or damage the generator.
