I got it! Press "set". You should see "start goal" in the bottom right. Press the user # you want to save as and press "set" again. The display will blink then display "0.0". Step on the scale to get your current weight. Once it's read you current weight, press "set". A goal weight will display. Press "User 1" to make your goal weight go up and "User 2" to make it go down. Press "set" when the display shows your goal weight. That's it. Now all you have to do is press your user # and wait for "0.0" to display before stepping on the scale.

I have a 10 year old Thinner bathroom scales also. Apparently the manufacturer designed it to make battery replacement hard so you'd buy a new scales. To replace the battery, if your unit is similar to mine, turn it over, remove all the screws and separate the top and bottom. You'll see the glass window that shows the weight. It is held in place by four tabs that are slightly twisted. Straighten them, lift the glass assembly clear without straining the wires, and turn it over to reveal the round black battery case. It is secured by three small screws and clear epoxy. Remove the epoxy with a knife blade, remove the screws, and separate the two halves of the case on one side being careful not to separate the other side where there is a metal connection piece. Using the knife tip, remove the CR2032 battery and replace it with a new one (available at Radio Shack or similar stores). Reassemble in reverse order; no need to replace epoxy. My scales worked fine after that.
