Using this soap dispenser is easy. First, insert 6 'D' cell batteries into the dispenser (batteries not included). Then, fill the 1-liter bottles with your favorite liquid soap. Place the dispenser in a high-traffic area like a bathroom or kitchen. To adjust the soap amount or other settings, use the included remote control. You can also disable the sensor when you need to clean or refill the dispenser. When it comes to maintenance, regularly check the battery level and replace the batteries when they're low. Clean the dispenser and the spout with a mild cleaner to keep it looking great. And remember, keep the dispenser out of reach of small children to avoid any accidents.
