DC balance adjustment (VR301)While observing the waveform with an oscilloscope at pin13 of IC301, adjust VR301 to minimize the waveform level.2. PLL control voltage adjustment (VC301)First

36、 set the transmission frequency to 87.9MHz with thecommander, then adjust VC301 so that the DC Voltage atthe +pole of C317, measured using a multi-meter or digitaltester, is +3V (0.1V).NOTE: E type is 87.7MHz.3. Modulation level adjustment (VR303)The method uses a standard receiver or tuner.Adjust V

37、R303 so that the output level from the standardreceiver or tuner is as specified.L.P.S initial position adjustment procedure1. Connect the changer to the H/U.2. While holding the magazine eject button of the changer,press the reset button of the H/U.3. After about 3 seconds, release the magazine eje

38、ct button.4. Press the SRC button of the H/U to enter the CD-CH mode,and the H/Us display section indicates “E-88“.5. Move the mechanism deck to around the 1st stage bypressing the DISC- or DISC+ button.6. Insert the adjustment tool (W02-0635-00) into the tool holeon the changer mechanism.7. Then pr

39、ess the DISC+ button to move the mechanism deckuntil the mechanisms slider hits the adjustment tool.8. When the motor locks (stops), press the REPEAT key ofthe H/U.When the REPEAT key is pressed, the mechanism movesautomatically to the 1st stage and the initial positionadjustment completes. (The dat
