Grab the shotclock by the clamp
click the tiny black button below the logo (between "For" and "H3MP")to turn on the device.
there're 3 menu screen, default is the timer mode, second is the sets settings, third is countdown seconds settings.
to change menu mode, click the "menu⬆" and "menu⬇", to set values, click the "set⬆" and "set/on⬇".
When everything is set, back to timer menu and click "set/on⬇" once to start countdown, second click to stop counting.
The clock only has very basic timing function but I'm sure it's enough for H3MP.

Thanks to Melon for the model!
1.0.0 Added the shotclock in Tools&Toys------>Utilities.
1.0.1 Now only one click per action on the buttons and the clock is much more stable.
