Make sure there are no obstacles between the remote and the device for a good signal. When not in use, keep it in a dry and clean place. Don't expose it to extreme temperatures or moisture. If the remote stops working, check the batteries. Replace them if they are low. Also, avoid dropping the remote as it may damage the internal components.
