Operation Guide USB Cable VAIO VPC-CA25FX USB Device 1) The VAIO VPC-CA25FX is powered by USB connection to a notebook computer using the included USB Cable. When operated at low fan rpm settings, the ON/OFF status of a VAIO VPC-CA25FX may not be audibly distinguishable, requiring a visual confirmation through the Power LED's ON/OFF status. When storing the VAIO VPC-CA25FX, preventing the accumulation of dust in the vents and inlets will maintain optimal sanitary and performance conditions. Notebook computers with relatively thick rubber feet increase the distance between the notebook computer and the VAIO VPC-CA25FX, facilitating enhanced airflow and cooling performance. 3 6.
