Just press the number corresponding to the disc you want to listen to. Note: • When a 12-Disc Multi-CD Player is connected and you want to select disc 7 to 12, press the 1 to 6 buttons for 2 seconds or longer. Disc Number Rough Search (for 50-Disc type only) This handy function lets you select discs loaded in a 50-Disc Multi-CD Player using the 1 to 5 buttons. The 50 discs are divided into five blocks, with each of the 1 to 5 buttons assigned to a block. • Select the desired block with the 1 to 5 button. Note: • After completing a rough search, use the 5 and ∞ buttons to select a desired disc. Displaying Disc Titles • Press the DISPLAY button, to change the Disc Title display of the current disc. Note: • If you switch displays when disc titles have not been input, “NO TITLE” is displayed. • Repeat the preceding operation to return to the normal display. Note: • The multi-CD player may perform a preparatory operation, such as verifying the presence of a disc or reading disc information, when the power is turned ON or a new disc is selected for play- back. “READY” is displayed. • When a magazine is loaded into a 50-Disc type Multi-CD Player, information on all the discs in the magazine is read. If you start playing a disc on a 50-Disc type Multi-CD Player before reading of information on all discs has been completed, reading of information stops part way through. This will prevent you from using the ITS function. (If you try and use this function, “NOT READY” is displayed.) If this happens, reading of information begins again when you switch to a component other than the 50-Disc type Multi-CD Player. • If the multi-CD player cannot operate properly, an error message such as “ERROR-14” is dis- played. Refer to the multi-CD player owner’s manual. • If there are no discs in the multi-CD player magazine, “NO DISC” is displayed. • “LOAD” will be displayed in the following cases: * If the disc in the extra tray is selected. * If the disc is moved from the extra tray to the magazine. (Refer to the 50-Disc type multi-CD player owner’s manual.) • You cannot use the “Ejecting a Single Disc”, “Frequency Play”, “Music Group Play”, or “ABC Disc Title Search” functions with this product. Switching the Multi-CD Player Using a multiple connection adapter lets you connect up to three Multi-CD players. M-CD 1 = M-CD 2 = M-CD 3 (Displayed for about 2 seconds.) Elapsed Play Time Indicator Disc Search Disc Number Indicator Track Number Indicator This product can control one or more multi-CD players. (There are some types of Multi- CD players such as “CDX-P630S” which you cannot connect more than one.)
