This electric timer is my dads and I dont have instructions for it, but last time I reset it it never even worked, so I gotta get this straightened out. K When I plug it in it first has the letter C, then it makes me put in a number(12),then I push mode and it says P, so I put (12), then it says E, (?) wth is the third number for? After I got that figured out I should be able to reset it properly, and hopefully then it will work.
