If you didn't understand the meaning of a word in users manual for your new DVD player where would you look first to find the definition?

If I didn't understand a Word in the user manual for my new DVD player, I would first look it up in an online dictionary or a reputable dictionary app for a clear definition. Alternatively, I might use a search engine to find the Word's meaning along with context or examples. If I had access to the internet, I could also check forums or support pages related to the product for clarification.
