I have a model 49550/TM151P and need a mauel as the instructions on the back are gone. How do I know if the manuel switch is in the on position? All I have to go by is on the top left is a clock picture and on the right is a circle with a straight line through it. I get how to put the pins in the on off places, it's not working. Here is what I am doing, set the time. Turn on the lamp, plug into timer, plug into wall. Immediately the light comes on and stays on. What am I doing wrong
