21、t it was loaded correctly (label side up) and that the CD unit is on a flat, level, stable surface. Check disc for dirt, scratches, spills, etc. If the disc spins but there is no sound, check the cable connections. If they are okay, check your amplifier or receiver. If the CD skips, check it for dir

22、t, oil or scratches. Do not assume that the CD player or laser is defective. Many CDs are recorded “out of spec” and skip on most or all CD players. Before sending the unit to an authorized Gemini service technician, insert a disc that plays properly in another unit. CDX-602 ROBO START INSTRUCTIONS:

23、 IN SINGLE-AUTO CUE MODE: Use ROBO START (25) in SINGLE-AUTO CUE MODE (5) to alternate play between the CDX-602s two CD players (one track from one side, then one from the other). In SINGLE-AUTO CUE MODE play starts immediately with no blank or “dead” space. ROBO START causes one side of the CD play

24、er to play when the other side is paused. 1. Engage SINGLE-AUTO CUE MODE with the SINGLE-AUTO CUE/ CONTINUOUS button. 2. Press the ROBO START (25) button to activate ROBO START. Play will alternate between the two CD players. At the end of a track, the playing side pauses and the other CD deck plays

25、 a track. At the end of this track, the playing side pauses and the first CD deck resumes play. IN CONTINUOUS MODE OR DURING NORMAL PLAY: If you use the ROBO START function without SINGLE-AUTO CUE MODE (in CONTINUOUS MODE or during normal play), CD deck play does not alternate automatically. PAUSE m

26、ust be pressed on the playing deck for the second deck to play. 1. During normal play, set a cue point on the second CD deck. 2. Press the ROBO START button to activate ROBO START. 3. Press PLAY/PAUSE BUTTON on the playing side to start play from the cue point on the other CD deck. NOTE: Pausing pla
