Dash Accessory Switches Rinker 360

Can anyone tell me what the 3 accessory switches on the lower right of the dash control? Pics attached. The previous owner made lots of changes and as far as I can tell these 3 switches don't control anything on my boat. I have radar, a MFD and a fishfinder/sonar but they are controlled by the electronics switch. Thank you.
