Using this product is a breeze. Just place your hands under the LED - guided towel activation zone, and the dispenser will give you a paper towel. For the waste receptacle, unlock and remove the front panel to empty it when it's full. You can power the unit using an AC adapter or 4 Alkaline 'D' Cells, but remember the batteries aren't included. When it comes to maintenance, regularly wipe the satin - finish stainless steel surface with a soft cloth to keep it looking good. If you need to change the type of dispenser or receptacle, you can easily do field conversion without replacing the wall cabinet. Also, make sure to use universal rolls with the correct core diameter and size as specified. And don't forget that you can interchange it with some compatible modules for different needs.
