CD mode 5.1 CD Key Functions 1) STOP Press this key when the CD plays will stop the CD play, but do not clear the repeat and programming state. Press this key when the CD stops, it will clear the repeat and programming state. 2) PLAY/PAUSE When CD stops, it will play if press this key, and display the CD track; When CD plays, it will pause if press this key, and the display flashes. 3) NEXT/FF Next track in selecting mode. Press this key less than 1 second; skip to next track in playing mode. Press this key less than 1 second, skip forward. 4) PREV/FW Last track in selecting mode. In playing mode, press this key less than 1 second; skip to last track and if the play time is over 3 seconds, than skip to the first track. In playing mode, press this key more than 1 second, skip backforward. 5) RAND Switch to random play state. Display rotative light in LED mode. Display RDM flag in LCD mode. 6) RPT Switch to single track or repeat the whole disk state. Press the key RPT to repeat the current track, and “RPT” flashes. Press the key RPT again; repeat the whole disk, and “RPT” display. 7) PROG Enter the programming state (active in STOP sate), and “PROG” flashes. Press REW/FF to select the music, and PROG is to store the music; Programming number increases by 1, and it can store 20 tracks at most. If there is no operation in 30 seconds, exit the programming state, while the tracks are reserved. After complete programming, press the key PLAY to enter the programming play state, and “PROG” lights. 8) OPEN/CLOSE When the CD tray is closed, if press this key, CD stops and is out of the tray. When the CD tray is open, if press this key, close the tray. 9) INTRO Press this key to enter the audition mode. Each music plays for 10 seconds (only in LCD 4digit mode).
