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.)
