Unpacking my Quantum, it was clear the inner box had been opened. It could be that the dealer wanted to make sure it was in good shape given the issues I experienced with my initial order. (They originally had 1 left in stock, but it turned out both the inner and outer box had been severely damaged, so I asked them to order me a new one rather than send a potentially damaged unit.) In my box I found the keyboard, the power cable, and the Quickstart manual. I have downloaded the full manual, but was surprised it didn't come in the box. Is there anything else I might be missing?
