I was gifted this awesome 1997 Sea Pine and as such I am still learning how to use it. I have read the sticky note on how to use a 3-way refrigerator but need some help still. Luckily the directions are still intact for how to use the gas- however I don't know if the first click of the noob is AC or DC and I don't want to risk draining my battery guessing and trying it out! Plus, my dear sweet husband insists that this model refrigerator will only run on gas, but I don't agree. As you can see in the picture the gas setting is clearly labeled, but the labeling for the AD & DC options have been worn away. Thanks!
