I've checked the following areas of the official manufacturers website: FAQ page, Downloads, Manuals and Troubleshooting, Capability, etc., but there is nothing to answer your inquiry. There is no manual for this device or something that I can check. The product, however, still appears on some websites, but it's nowhere mentioned about the scanning support and all the available modes.
