Wadia 27 owners I need help

Can someone tell me about the dip switches in the 27. I have the switch settings but I need to know how are the switches to be set. one side of the switch has the numbers 1234 and the other side say open. I need to know what position does the switch to be? The switch up on the open side is open? or switch down on the open side open? it does not state in the instructions. Please help
Picture the Dip as a ski slope and when you want to close say switch 2 and 4 they should bow down to the number like you are skiing down the slope to close the circuit while all others are going up hill..... Got it ?
