How to Replace Dead Doorbell Batteries For Dummies

The batteries on this model of doorbell can be located by gently prying out the upper top little panel section. It's a small battery drawer-like slide piece that comes out. I used a flathead screwdriver. You can see that there is a test button on the front of the doorbell. As can be heard in the video, when the button is pushed before the battery change out, there is a barely audible sound. Once  the batteries are changed out it is obvious that the doorbell is functioning as it should when the test button is depressed again.
