The Lacrosse Technology WT-3101 user manuals available on the Internet are too simplified. They do not describe how to use all the controls. They simply say, place battery, and press time zone button. I tried that, but it does not work. There are pins in the top left corner of the control panel on the back of the clock. I tried shorting these. There is a tab about three inches below the pins that I tried pressing. And there is a smaller button above between the CT and ET buttons, which I tried pressing. They all have specific functions described in earlier manuals, but I lost them, and I don't remember exactly how to use them. Please tell me how to use them, and to set and start my clock. It worked for years, and they stopped. I put in a new battery. thanks Ben
