I would like to use the TIMY as a bottom hand timer but can't figure out how to put the bib number in after I have hit the stop time key.
Please help

you can't do it after the fact unless you go thru the edit function. Depending on the program you are using you can change the bib number by entering it on the keyboard and pressing the green ok for the start bib or the red ok button for the finish bib. In back up mode you use the green ok in stopwatch and training you use both.
