Countdown Timer: Enable this setting if you prefer the timer to countdown rather than show the elapsed time.

Brightness Warning: Turn off to disable the popup warnings. Be sure you have read the warning and understand how to use the red and green safelight modes before disabling.

Interval Delay: Set the number of seconds (10-300) the timer will wait between steps. The Autostart Timer setting must be enabled for the delay to take effect. The Interval Delay will be applied to all steps.
