Hi JM HERNANDO MS, To assist you in learning the various features, functions, and settings of your Q80D TV and remote, you can download the Q80D TV's User Manual, e-Manual, Remote Control Leaflet, and Quick Setup Guide on Samsung's website under ‘Support’ (top right corner) > Manuals & Software > TVs & Home Theater. From there, you can select the Q8D TV under QLED 4K TVs > D Model Lineup to download the guides you would like. The e-Manual and Remote Guide are both also embedded into the TV itself under Menu > Settings > Support. If you need more help, Samsung is here for you. Please call us at 1-800-SAMSUNG, 8AM - 12AM EST, 7 days a week. Our LiveChat agents are also available by clicking on the ‘Support’ link on our website. ~Samsung Advisor
