Volume on Doorbell Audio Way Too Loud!

I have just installed a battery powered Ring Video Doorbell. The problem we have is when we allow the audio to speak with anyone outside the volume is way way too loud!! Any noises/voices in the house boom out loudly and anyone within 20 yards of the house can hear anything being said through the intercom. This is a serious privacy concern but I have no idea how to set the volume at a much lower level. Also, there is a volume slider for a ringer but I have no idea what this ringer is. When I first installed it the ringer volume was almost at the max and now I've put it down to the lowest level but I have no idea what it is.
