While holding the maga-zine eject button of the changer, press the reset button ofthe H/U and, in about 1 second, release the magazine ejectbutton. Press the CD button of the H/U to enter the E-
15、88mode. Move the mechanism deck to around the 1st stageby pressing the DISC- or DISC+ button.Insert the adjustment tool into the tool hole on the changermechanism. Then press the DISC+ button to move themechanism deck until the mechanisms slider hits theadjustment tool. When the motor locks(stops) p
16、ress theREPEAT key of the H/U.When the REPEAT key is pressed, the mechanism movesautomatically to the 1st stage and the initial position ad-justment completes.
