In this case, execute the procedure on the right toreset the microcomputer and return the unit to the normal condi-tion. CRResetting the microcomputer clears the memory you entered andreturns it to the initial condition when the unit left the factory.1With the power cord plugged in, turn the POWER key toOFF.2While holding down the (ON/STANDBY) key, pressthe POWER key.Please note that the following items will be deleted fromthis units memory if the power cord is disconnectedfrom the AC outlet for approximately three days.Memory backup functionCRThe frequency setting is cleared and 87.5 MHz is selected.CRThe preset station memory is cleared.CRThe surround setting is cleared and reset to the initial condition.CRThe input selection is cleared and the “Tuner”input is selected.CRThe volume setting is cleared and the volume is set to “-66 dB”.CRThe receiving band setting is cleared and the “FM”band isselected.AccessoriesCautionsKRF-X9992D(K) COVER1,1P( 99.11.1 6:53 PM yW23ADJUSTMENTKRF-X9992D/X9992DENo.ITEMINPUTSETTINGSOUTPUTSETTINGSRECEIVERSETTINGSALIGNMENTPOINTSALIGN FORFIG.1DISCRIMINATOR(A)98.0MHz 1kHz,±40kHz dev.70dBf (ANT. input)Connect aDC voltmeterbetween CN12 1and CN12 2(X11)MONO98.0MHzL604(X11)0V(a)2DISTORTION(MONO)(A)98.0MHz 1kHz,±40kHz dev.
