82 2000/3000 X-Series Oscilloscopes Service Guide7 Safety NoticesWarningsBefore turning on the instrument, you must connect the protective earth terminalof the instrument to the protective conductor of the (mains) power cord. Themains plug shall only be inserted in a socket outlet provided with a protectiveearth contact. You must not negate the protective action by using an extensioncord (power cable) without a protective conductor (grounding). Grounding oneconductor of a two-conductor outlet is not sufficient protection.Only fuses with the required rated current, voltage, and specified type (normalblow, time delay, etc.) should be used. Do not use repaired fuses or short-circuitedfuseholders. To do so could cause a shock or fire hazard.If you energize this instrument by an auto transformer (for voltage reduction ormains isolation), the common terminal must be connected to the earth terminal ofthe power source.Whenever it is likely that the ground protection is impaired, you must make theinstrument inoperative and secure it against any unintended operation.Service instructions are for trained service personnel. To avoid dangerous electricshock, do not perform any service unless qualified to do so. Do not attemptinternal service or adjustment unless another person, capable of rendering first aidand resuscitation, is present.Do not install substitute parts or perform any unauthorized modification to theinstrument.Capacitors inside the instrument may retain a charge even if the instrument isdisconnected from its source of supply.Do not operate the instrument in the presence of flammable gasses or fumes.Operation of any electrical instrument in such an environment constitutes adefinite safety hazard.Do not use the instrument in a manner not specified by the manufacturer.
