lSERVICE PROCEDURE1. Tracking point memoryThis service procedure can be used for measurement of the tuner circuit.With the POWER ON, press the "PRESET UP" button while pressing the "MEMO" button for atleast 3 seconds or more. FLO will display "TRACKING". Frequencies will be memorized asfollows:VERSION P1FM 90.0SCAN STEP P5 P6 P7 PB pg PlO Pll P12~P3010 KHz 600.0 1000.0 1400.0 520.0 +- +- +- +-MW 9 KHz 603.0 999.0 1404.0 531. 0 +- +- +- +-LW t t t 171. 0 207.0 270.0 152.0 531.02. FLD segment illuminationThis service procedure will illuminate all segments by the following steps :With the POWER ON, press the "FM/AM(TUNER)" button while pressing the "MEMO" button forat least 3 seconds or more. This procedure takes 1 minute and 40 seconds to finish; at this pointthe procedure is complete.1. All segments will be illuminated for 5 seconds.2. At the grid "1 G", segments are illuminated in the following order:CD KHz -+ CV MHz -+ @ R -+ @ PEAK -+ @ L -+ @ MULTI -+ (J) MONO -+ @ MATRIX -+® HALL -+ @) P-SCAN -+ (U) TAPE -+ @) COPY -+ @) VCR1 -+ @ SLEEP -+ ® DISP -+ ®l TX3. At the grid "2G", to "11 G", each segment is illuminated individually.4. At the grid "12G", segments are illuminated in the following order:CD VISUAL-+ CV SIGNAL LEVEL-+@ CH-+@ SIGNAL BAR (LEFT SIDE) -+@ SIGNAL BAR (2nd LEFT) -+@ SIGNAL BAR (CENTER) -+ (J) SIGNAL BAR (2nd RIGHT) -+@ SIGNAL BAR (RIGHT SIDE) -+®STEREO-+@) THX CINEMA-+ (U) PRO.LOGIC-+@ MOVIE-+@) AUTO MEMO-+@ 3.LOGIC-+ ® SIMUL'D-+ ®SURROUND3. Selector check modeThis service program automatically operates input selector and surround mode by the followingprocedure. This service program continually repeats until power is shut off.When the POWER ON, press the "SURROUND MODE+" button while pressing the "MEMO" button3 seconds or more.STEP INPUT DSP FM MODE FREQUENCY COPY SWITCH NOTESSELECTOR MODE BAND TAPE VCR11 FM STEREO AUTO 98.0 SOURCE SOURCE2 FM STEREO MONO LAST t t3 CD THX AUTO LAST t t4 TAPE1 P-LOGIC AUTO LAST TUNER SOURCE TUNER-ON5 TAPE2 MOVIE AUTO LAST SOURCE TV6 TV 3CH AUTO LAST t SOURCE7 TV HALL AUTO LAST CD LD8 LD MATRIX AUTO LAST TAPE2 TV9 VCR1 MONO AM/MW 1000/999 TUNER VCR210 VCR2 STEREO AUTO 98.0 TUNER SOURCE TUNER-ON11 AUX THX AUTO LAST SOURCE AUX4.
