Page 6: General Information
1. General Information Safe and effective RF lesioning is dependent not only on equipment design, but also on factors under control of the operator. Do not attempt to operate the G4 prior to completely reading and understanding the instructions for use.
Page 7: Electrical Safety Information
IEC 61000-4-2 (2001), 61000-4-3 (2006), 610004-4 (2004), 61000-4-5 (2005) 1.3 Electrical Safety Information The G4 is a radiofrequency generator designed to produce local tissue heating at the tip of an electrode by the presence of radio frequency current. Special isolation transformers are imposed between power lines and internal G4 circuitry, resulting in very low leakage current.
Page 8 WARNING: The use and proper placement of dispersive electrodes is a key element in the safe and effective use of this lesion generator, particularly in the prevention of burns. Read and follow Cosman’s dispersive electrode instructions for preparation, placement, surveillance, removal and use of any dispersive electrode.
Page 9 NOTICE: Always record the wattage readings that correspond to a given temperature for a given technique. This gives extra guidance and helps Cosman Medical diagnose problems. WARNING: Proper electrode placement should be verified using anatomical...
