Operation
Auxiliary Power Outlet
The Power Console is equipped with a front auxiliary power outlet. This
outlet contains a noise filter that is optimized for video and is a convenient
place to connect video cameras, digital still cameras, MP3 players, or any
other portable device in need of AC power. Simply remove the small door
covering the outlet by sliding it to the right (Fig. 4) and plug in your device.
This outlet is always live (always-on) when the Power Console is plugged
into AC power. The "Switched" button does not control the auxiliary outlet.
