The "melody" cannot be interrupted once it begins. I think you can turn it off and then help your husband. In particular, it is pointed out that you should never use detergents or a WET cloth to clean the devices. The product description said it was waterproof. That's why I chose this model. https://images-na.ssl-images-amazon.com/images/I/71ztqyFC1HL._AC_SX679_.jpg
