WARNINGCheck for radiation leakage after every servicing. Should the leakagebe more than 2 mW/cm 2 (1mW/cm 2 for Canada) inform PASC, PSC,or PCI immediately. After repairing or replacing any radiation safetydevice, keep a written record for future reference, as required byD.H.H.S. and Health and Welfare Canada regulation. Thisrequirement must be strictly observed. In addition, the leakagereading must be recorded on the service repair ticket while in thecustomer’s home.NOTE:The U.S. Government standard is 5 mW/cm 2 while in thecustomer’s home. 2mW/cm 2 stated here is our ownvoluntary standard. (1mW/cm 2 for Canada)12.1. Equipment•••• Electromagnatic radiation monitor•••• Glass thermometer 212°F or 100°C•••• 600cc glass beaker12.2. Procedure for measuringradiation leakageNote before measuring.•••• Do not exceed meter full scale deflection. Leakage monitorshould initially be set to the highest scale.•••• To prevent false readings the test probe should be held bythe grip portion of the handle only and moved along theshaded area in Figure no faster than 1 inch/sec(2.5cm/sec).•••• Leakage with the outer panel removed ...... less than5mW/cm 2 .•••• Leakage for a fully assembled oven with door normallyclosed ...... less than 2mW/cm 2 (1mW/cm 2 for Canada).•••• Leakage for a fully assembled oven [Before the latch switch(primary) is interrupted] while pulling the door ...... less than2mW/cm 2 .1. Pour 275 ± 15cc (9ozs s ± 1/2oz) of 20°C ± 5°C (68° ± 9°F)water in a beaker which is graduated to 600cc, and place inthe center of the oven.2. Set the radiation monitor to 2450MHz and use it followingthe manufacturer´s recommended test procedure to assurecorrect results.3. When measuring the leakage, always use the 2 inch (5cm)spacer supplied with the probe.4. Tap the start pad or set the timer and with the magnetronoscillating, measure the leakage by holding the probeperpendicular to the surface being measured.12.2.1. Measurement with the outer panelremoved.Whenever you replace the magnetron, measure for radiationleakage before the outer panel is installed and after allnecessary components are replaced or adjusted. Special careshould be taken in measuring around the magnetron.WARNINGAvoid contacting any high voltage parts.12.2.2. Measurements with a fullyassembled oven.After all components, including outer panel are fully assembled,measure for radiation leakage around the door periphery, thedoor viewing window, the exhaust opening and air inletopenings.12.3. Record keeping andnotification after measurement•••• After any adjustment or repair to a microwave oven, aleakage reading must be taken. Record this leakagereading on the repair ticket even if it is zero.A copy of this repair ticket and the microwave leakagereading should be kept by repair facility.•••• Should the radiation leakage be more than 2 mW/cm 2(1mW/cm for Canada) after determining that all parts are ingood condition, functioning properly, and genuinereplacement parts as listed in this manual have been used,immediately notify PASC, PSC or PCI.12 PROCEDURE FOR MEASURING MICROWAVE ENERGYLEAKAGE21NN-S262SF / NN-S262BF / NN-S262WF / NN-S252BF / NN-S252WF
