9、T CHECKMeasure leakage current to a known earth ground (waterpipe, conduit, etc.) by connecting a leakage current testerbetween the earth ground and all exposed metal parts of theappliance (input/output terminals, screwheads, metaloverlays, control shaft, etc.). Plug the AC line cord of theappliance
10、 directly into a 120V AC 60Hz outlet and turn theAC power switch on. Any current measured must not exceedo.5mA.ANY MEASUREMENTS NOT WITHIN THE LIMITSOUTLINED ABOVE ARE INDICATIVE OF APOTENTIAL SHOCK HAZARD AND MUST BECORRECTED BEFORE RETURNING THE APPLIANCETO THE CUSTOMER.DeviceundertestTest allexpo

18、Seepage 16 for more information on configuringspeakers.) The letters inside each of the centerboxes display active input channels.For standardanalog inputs,only the L and R will light,indicat-ing a stereo input.When a digital source is play-ing,the indicators will light to display the chan-nels begi
