ADJUSTMENT
LPS initial position adjustment procedure
Connect the changer to the H/U. While holding the maga-
zine 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 ad-
justment completes. (The data is written in the E2PROM
at this time.)

CAUTION : For continued safety, replace safety critical components only with manufacturer's recommended parts (refer to parts list).
Indicates safety critical components. To reduce the risk of electric shock, leakage-current or resistance measurements shall be
carried out (exposed parts are acceptably insulated from the supply circuit) before the appliance is returned to the customer.
!
• DC voltages are as measured with a high impedance voltmeter. Values may vary slightly due to variations between individual instruments or/
and units.
