I'm not sure if you can reset your user settings (like lighting and tones and what not) but you can reset each individual model settings. Let's say you want to reset model 1 for a 777. First you need to make sure model 1 is active. Go to MDL-SEL (it's location may vary dependingon the setting for LEVEL-SEL). Anyways, choose M1 and hold the +and- buttons together for a second or so (it actually says "reset" on the controller). Once you're in the model you want to reset go to MDL-RES. It'll just prompt you to push the +/- keys. Once you do that you're done. Hope this helps.
