In my attempts to locate a manual for your particular model number... I found a site that claims to have said manual... but it is a pay site. I did however find a manual in PDF format for a similar model that may help you:

But I cannot guarantee you that you will be satisfied with your results on the site as I have never actually used the site. In case you want to try it, here is the URL:
