Description
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.)
