A:Answer Well, this is my least favorite feature of this newer griddle. First, keep in mind that the knobs features work kind of like an old digital clock. That is to say, once you have input one setting, it will automatically proceed to the next one, usually with flashing LEDs. After you have pressed the 'ON' button move over to the rotory knob.The display will flash GRILL or GRIDDLE at the upper left and right of the screen. Just twist the knob toward the selection you desire and then push the knob in until it clicks, and makes a little beep. Then move on the the rest of the settings such as temperature, or time. Twisting right will raise the temp, twisting left will lower it. After you set your proper temp push in the knob and then move on to time. Twist left to count down from an hour (auto off) or twist right to add time from zero in 30 second increments, push in to set the timer keeping in mind that it won't start until your preheat temperature has been reached then it will run to auto off when the timer runs out. The most difficult thing in this process is to get the preheat cycle to engage. . . but if you let the display flash about five times before pushing the knob in, it often helps. However, I have found the preheat function to be finicky and fickle. Despite this little flaw I enjoy my Griddler 5 very much, I hope you will too. PS sometimes it helps to let the grill cool and reset itself by just turning it off then back on.
