This is a set including the main unit, power cable, two types of antennas, a remote control, and a set of 5 new, unopened MD discs. Regarding the instruction manual, you can find it by searching for the model number of the main unit. Please find it on the KENWOOD website and print it out. The warranty period has long expired, but according to the warranty card, the purchase year was around 2005. The purchase price was 26,500 yen. (Please refer to the 15 photos.) Functionality check: CD: Only the CD function is unusable. In the past, the main unit was dropped from a low table, and a disc got stuck inside, making it unusable. Radio and MD functions worked without any problems. The remote control battery is dead, and the remote control is currently not working, but it should work again if you replace the button battery. There are two scratches on the front right side of the main unit, which appear to have been caused when it was dropped (please refer to photos 9 and 10). However, as this is a used item, we cannot guarantee how long it will last.
