D WARRANTY LIMITATION OF WARRANTY Safety Precautions The following safety precautioos should be obsewed before using this product and any asno- ciated instrumcntatioo. Although some inrtromeots and accessories woold nonnally bo used with nowhazardous voltages, there arc situations wberc hazardous conditions may be present. This product is intended for use by qualified personnel who rccogoiu: shock hazards and are familiar with tbc safety pnxaotions rcqoircd to avoid possible injuly. Read lbe operating it]- formation carefully before using the product. `The types of product users arc: Kesponsiblc body is tbe iodividunl or group responsible for the USCsod owinleoaoce of equipment, for ensuring tlnt the equipment ia operated within its spccilications and operat- ing limits, and for ensuring that operators are adequately trained.
