Resumen del manual
$ Playing discs The display is wrong or play won’t start. The total number of tracks displayed differs each time the same disc is inserted. Unusual sound is heard. CD-RW cannot be read. “VBR–” is displayed instead of the remaining play time. “TAKE OUT/DISC” appears on the display. The disc may be upside down. 8 Wipe the disc. Replace the disc if it is scratched, warped, or non-standard. Condensation may have formed inside the unit due to a sudden change in temperature. Wait for about an hour for it to clear and try again. The disc may be scratched, or its data may be defective. Replace the disc. The disc was incompletely formatted. Use the recording equipment to fully format the disc before recording. The unit cannot display the remaining play time for variable bit rate (VBR) tracks. There is a problem with the disc mechanism. (A power failure may have occurred.) The tray will open automatically. Remove the disc from the tray, and after ensuring there is no disc in the tray, close it. The unit will make the disc changing noises for a few moments and then it should operate normally. Remote control Remote control doesn’t work. Check that the batteries are inserted correctly. 4Replace the batteries if they are worn.
