Unfortunately, there is no manual available in English language. I have searched everywhere, including the official website, even though that website is in Spanish. Google Search or any other searching engine don't provide anything useful about it, which means it doesn't exist one.
You could try a way to obtain the English user guide: Go to website and click Soporte > Enviar una Solicitad. Use Google Translate to translate from English to Spanish and then paste the text on the website. In the text you should ask them if there is an English guide available for the product you have.
