    Safety Information The general safety information in these pages is for both operating and servicing personnel. In addition, specific warnings and cautions appear throughout the manual where they apply. Definition of Terms and Symbols In this manual, a CAUTION flag identifies a potential for equipment or other property damage.
  • Page 13 Safety Summary Grounding the Instrument The instrument is grounded through the grounding conductor of the power cord. To avoid electric shock, plug the power cord into a properly wired receptacle before connecting to the product input or output terminals. Danger Arising from Loss of Ground If you lose the protective ground connection, all accessible conductive parts (including knobs and controls that appear to be insulating) can render an electric shock.
