2-5 Sales Demonstration Lock Function
This function prevents discs from being lost when the unit is used for sales demonstrations, by disabling the disc eject function.
"LOCKED" is displayed on the unit, and ordinary operation is disabled.
2-5-1 Setting Method
The sales demonstration lock function is set by simultaneously pressing the "POWER" button of DVD Player on the remote
control unit and the "STOP" button on the main unit. ("LOCKED" is displayed when the lock function is engaged.)
2-5-2 Release Method
The function can be released using the same procedure as for setting. If the remote control unit is not at hand, the function can
be released by using the same method as for player initialization (pressing the "PAUSE," "4" and "OPEN/CLOSE" buttons
simultaneously).
