oGo works like a set of orienteering traffic lights.
Green: A runner may start when their course is showing a green "runner".
Red: As a runner starts the starter presses the course's start button and the "runner" figure changes to a red "standing" figure. The next competitor must wait as oGo counts down to the next start.
Amber: Four seconds before the countdown ends the "standing" figure changes to an amber "get-ready" figure and a "beep-beep" alert starts.
Green: When the countdown reaches zero the green "runner" returns and the next competitor may start immediately or any time after that.
Each course may be configured with its own name, start interval and start button colour. oGo can time starts for up to eight courses per event and store configurations for four events. oGo also keeps a count of the number of starts.
Sound volume, display timeout & brightness are set through the device’s own settings, e.g.:
An event may be reconfigured while in progress e.g. to reduce start intervals if a queue has formed.
Default settings are:
Configurable button colours are: black, brown, blue, light blue, green, light green, red, orange, yellow and white. Configurable start intervals are: 10s, 30s, 45s, 1 min, 1 min 30s, 2 mins, 3 mins, 4 mins, 5 mins and 10 mins.
