ADJUSTMENT

LPS initial position adjustment procedure

Connect the changer to the H/U. While holding the magazine eject button of the changer, press the reset button of the H/U and, in about 1 second, release the magazine eject button. Press the CD button of the H/U to enter the E-88 mode. Move the mechanism deck to around the 1st stage by pressing the DISC- or DISC+ button. Insert the adjustment tool into the tool hole on the changer mechanism. Then press the DISC+ button to move the mechanism deck until the mechanism’s slider hits the adjustment tool. When the motor locks (stops) press the REPEAT key of the H/U. When the REPEAT key is pressed, the mechanism moves automatically to the 1st stage and the initial position adjustment completes. (The data is written in the E2PROM at this time.)
