Error Code FIP4.1 Level 1 FIPFIP1.1 NVM Error*1: Though some kind of foreign noise would be possible cause, go to [FIP1.42 Electrical Noise] andcheck, to make sure.Step Check Yes NoPossible causes:HVPS/MCU (PL12.1.19)1 Does Error occur when the power is turned ON? Go to step 4. Go to step 2.2 Does Error still occur when the power is turned OFFand ON again? Go to step 4. Go to step 3.3 Does Error still occur after several ON/OFF proceduresof the power? Go to step 4. End of work *14Checking HVPS/MCU non-volatile memory setup modeIs non-volatile memory setup mode accessible? Checkusing Chapter 2 Diagnostic [ADJUSTMENT PARAME-TER INTIALIZE MODE].Go to step 5. Replace HVPS/MCU. (RRP12.10)5Checking NVRAN for data setupAre all NVRAM data set appropriately?Check using Chapter 2 Diagnostic [ADJUSTMENTPARAMETER INTIALIZE MODE].Go to step 7. Go to step 6.6Checking Error after changing HVPS/MCU data setupChange NV RAM data to the correct setup value, andthen turn the power ON again.Does Error still occur?Replace HVPS/MCU, then go tostep 7.(RRP12.10)End of work7 Checking after replacing HVPS/MCU Does Erroroccur?Go to FIP1.42Electrical Noise.
