The following general safety precautions must be observed during all phases of operation, service, and repair of the component. Failure to comply with these precautions or with specific warnings elsewhere in this document violates manufacturer safety standards and intended use of the component. Mark Levinson assumes no liability for failure to comply with these requirements. Ground the Instrument To minimize shock hazard, the component chassis and cabinet must be connected to an electrical ground. The component is equipped with a three-conductor AC power cord. The power cord must be connected to either an approved three-contact electrical outlet or a three-contact-to-two-contact adapter with the grounding wire (green) firmly connected to an electrical ground (safety ground) at the electrical outlet. The power jack and mating plug of the power cord meet IEC (International Electro-technical Commission) safety standards. Do Not Operate in an Explosive Atmosphere Do not operate the component in the presence of flammable gasses or fumes. Operation of any electrical component in such an environment creates a definite safety hazard. Keep Away from Live Circuits Operating personnel must not remove component covers. Qualified maintenance personnel must make component replacements and internal adjustments. Do not replace components when the power cord is connected. Under certain conditions, dangerous voltages may be present even when the power cord is disconnected. To avoid personal injuries, always disconnect the power cord and discharge circuits before handling them. Do Not Service or Adjust Alone Do not attempt internal service or adjustment unless another person capable of rendering first-aid resuscitation is present. Do Not Substitute Parts or Modify Component Because of the danger of introducing additional hazards, do not install substitute parts or perform any unauthorized modifications to this component. Dangerous Procedure Warnings Warnings such as the example shown below accompany potentially dangerous procedures throughout this document. Instructions contained in these warnings must be followed. WARNING - DANGEROUS VOLTAGES CAPABLE OF CAUSING DEATH ARE PRESENT IN THIS COMPONENT. USE EXTREME CAUTION WHEN HANDLING, TESTING, OR ADJUSTING. - DISCONNECT ALL POWER TO THE COMPONENT PRIOR TO INSTALLING THE PHONO MODULES. Safety Summary

ESD (Electrostatic Discharge) Precautions CAUTION The following practices minimize possible damage to circuit board assemblies resulting from electrostatic discharge or improper insertion: - Keep circuit board assemblies in their original containers until ready for use. - Avoid having plastic, vinyl, or Styrofoam in the work area. - Wear an anti-static wrist strap. - Discharge personal static before handling circuit board assemblies. - Remove and insert circuit board assemblies with care. - When removing circuit board assemblies, handle only by non-conductive surfaces. Never touch open-edge connectors except at a static-free workstation*. - Minimize handling of circuit board assemblies. - Do not slide circuit board assemblies over any surface. - Insert circuit board assemblies with the proper orientation. - Use anti-static containers for handling and transporting circuit board assemblies. * To make a static-free workstation, wash a plastic-laminated workbench with a solution of Lux liquid detergent. Allow to dry without rinsing. 3 Mark Levinson and the Mark Levinson logo are registered trademarks of Harman International Industries.
