I have a potterton ep2000 need to know what the buttons say?

The controls to my heating you know the thing with the digital clock on it lol Well its that old that i can no longer see what each control does and am trying to set it on a timer but have no clue how because i dont know what each button means :( If someone could let me know if i can get an image of the manual maybe a picture with labels telling me what each control does that would be great thanks :D
