==== Volume Buttons ====
Two volume level buttons are displayed in the app unless the app setting Use Phone's Volume Buttons option (Android only) is selected. These buttons (or the phone volume buttons while the app is active) control the volume of the inside speakers that monitor the ringing system, including the church PA system if it is connected to the Audio Inside line output jack. You must have the [[Administration_MS#Mobile_App_User_Permissions|administrator's permission]] to be able to adjust the level.
