Time and Temp into Lamp Test Mode
To enter the option menu push the SELECT and INCREASE buttons simultaneously, then release.
When in Lamp Test Mode you can alternate between different patterns by using the Increase switch. Some signs have 3 different Lamp Test modes (use the Increase switch to alternate between different patterns) . Once done with the lamp test mode you can use the Select switch to toggle through the remaining functions (listed on your controller) until you return to the Display Mode.
and so on….. Some E.D.S. signs have only 5 options and others may have 21 options.
