Hi Vernon and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, it would appear that this product is not a local purchase.
The Sanyo ND-SB541DT / Gorilla is a JDM (Japan Domestic Model) product. A JDM product is intended for Japan's local use only and therefore, the language is restricted to only Japanese. As such, it has no option/feature for an English language nor is there a manual in English.
I realize that the above information may perhaps be not what was expected. Unfortunately, it is a design limitation; sorry for having to be the bearer of bad news.
