One by one mode can be used to time many competitors on a course for which each start is individual and sequential, like in an alpin slalom skiing race.

Start X button: Initially, this button starts the session and the first competitor. Pushing the button one more time will start the next competitor whose number is indicated on the button.

Stop X button (blue): When a competitor crosses the finish line, a press on the stop button, that shows its number, will time its race. A maximum of four Stop X buttons can be displayed at the same time. It means that a maximum of four competitors can be simultaneously in the course.

Stop / Reset button: When it is red, a press on this button will interrupt the session. When it is black with yellow lines, a press will reset the session.

Skip / Resume button: When it is blue, a press on this button will skip the competitor whose number is shown on the Start button. This action allows the next competitor to be started. When it is green, a press will resume the session that was interrupted.

Display the time since the beginning of the session (the start of the first competitor).

By default, this display shows the competitors by number. A zero time indicates a competitor running in the course. Between brackets, the classification order is shown.

By changing a parameter in the setup, the classification is shown. For each line, information displayed is classification, competitor number and time. Running competitors (with zero time) appear at the bottom of the list.

Determine which order will be displayed between competitors number and classification.

Default value: By number.
