I had never used a convection oven either and did not get a manual. I went online and put in the make and model and found the owners manual. I printed a copy which had the instructions for how to use the different features. I have been baking in the convection oven for 2 years now and love it. Either reduce your temp by 25 degrees, or use the temperature recommended in the recipe but reduce the time by 5 minutes. Mine browns things faster also, so just watch things as you are first learning to use it.
