Thank you for viewing. The direct sales from the cado store have ended, and the limited colors are very rare, including used items. Please consider it. ■ Product cado STEM 630i HM-C630i BLACK PREMIUM (Direct store limited color) List price ¥50,820 (tax included) I have confirmed that there are no noticeable scratches or stains, but please refrain from purchasing if you are sensitive to such things. The filter cartridge is a consumable item, so please purchase a new one. If you do not need it, please let me know when you purchase it. I will dispose of it for you. ■ Notes Even if there is water in the tank, the red blinking light indicating an error related to water supply or drainage may appear on the lower tank indicator. As per the guidance from the cado support center, this is not a malfunction but a phenomenon that occurs because it takes time to start operation from water supply. When using it for the first time or after cleaning the main unit, when operating from a state where there is no water in the water tank of the main unit, it takes time to supply water, so it takes time from pressing the power button to starting operation. (It may take about 10 minutes if the tank water level is low.) When refilling water from the water supply notification (the lower tank indicator blinks red), restarting operation from a state where there is little water in the water tank is the same. Please try increasing the tank water level, as it will speed up the start of operation. (It takes about 1 minute if the tank water level is full.) ■ Remarks ・To avoid trouble, please be sure to ask questions in the comment section in advance regarding the product condition and any other unclear points. ・Regarding the images posted, the actual color may differ from the actual color depending on the way the light hits it outdoors or indoors, and the viewing environment such as a computer or smartphone.
