I would like to answer your kind comments step by step as follows. 1. I am sorry. Enclosed please find a file. 2. The EUT has connectors for USB, IEEE1394 and DC input port. The DC input port maybe connected to the AC/DC Adapter. So, we connected the DC input port for the EUT with AC/DC Adapter. 3. The EUT be powered by USB port or IEEE1394 port from a personal computer, but the reason has the DC input port want to supply additional voltage, if the EUT need more current to operate functionally in certain case. Usually the EUT was operated by USB or IEEE1394 port only, so user does not need to connect DC input port. The applicant does not supply AC/DC Adapter with the EUT. In this case we have to submit the photo for the AC/DC Adapter. Please confirm me your smart opinion. Best Regards, Y. G. Gwon ONETECH Corp. ONETECH Testing & Eval. Lab EMC Div.
