(2) It is displayed on FL display as PLEASE and WAIT blink alternately, and while it blinks, pushing the EJECT button of a main body is continued. (3) After a while, a tray opens (About 20 seconds). (4) A disk is re

22、moved, the tray is pushed, and a tray is made to close. (5) PLEASE and WAIT blink alternately and it is displayed in FL indicator, and it will be in a standby state.
