AmScope40X-3000X Plan Koehler Laboratory Research Grade Trinocular Compound Microscope

I'm new to microscopes, zero experience, and I'm on a budget. I purchased this model T570D directly from Amscope with additional 15% discount on already very low price. I was very happy when unpacked it - beautiful piece of machinery! It came with 4 high quality objectives (maximum you can install up to five objectives): all four objectives have high quality PLAN optics and three out of four also have infinity sign on objective. It came without manual and Amscope suggested to download manual from Amscope website. Problem is that there is no manual for this microscope on Amscope website, even Amscope technical support cannot find one for me. Description for this product says that it has "infinity corrected optical system" but when I asked Amscope customer support to confirm that this is Infinity type microscope they told me that this is not infinity microscope (but it came with three infinity type objectives??? – how this could be explained?) they told me that product description for this item is wrong and they will correct it. Bottom line without microscope manual I cannot confirm the capabilities of this microscope and Amscope customer support is still looking for manual for the last two weeks. I start thinking to return it back, since I cannot use it for my research without knowing all specs of this microscope (need to buy video camera and some other objectives but without microscope manual it could be a total waste of money), too bad, it looks so beautiful!
