Need DIP switch settings for older PDQ dryer timer

[GoBuckeyes]

I have an older PDQ dryer timer, the simple nothing but count down LED type (Model L 4901). Can someone tell me what the 7 DIP switches in the timer correspond to? Its currently set for 70 seconds and I would like to change it to 60 but have no idea what switches to change. Thanks!
