Reset = left button
Start/Pause = right button
Mode select = Switches {R2, T1}
Initial value set = Switches {W13, W14, V15, W15}, {W17, W16, V16, V17}
There are 4 different modes slsected by using the corresponding binary number
- Count up from 00.00 to 99.99
- Count up from a preloaded second value to 99.99
- Count down from 99.99 to 00.00
- Count down from a proloaded second value to 00.00
Each set of initial value switches sets one of the second digits. The decisecond and centisecond digits cannot be preset.
The mode can only be changed after a reset.
