A good rule of thumb when using the bake/roast function is to reduce the temperature by 25 degrees and keep the cooking time the same as it says on the package. I found this to be the case with the temperature but not the timing. Even with the reduced temperature, the canned cinnamon rolls cooked quicker than the recommended time on the package. So, I would recommend keeping an eye on your cinnamon rolls and checking them to see if they are finished cooking after about 10 minutes.
