able to remove the black bars (see the TV manual for information about zooming
4:3 video).
This may occur on a 4:3 TV if the 4:3 OVERRIDE setting is OFF. To set 4:3 SD
programming to fill the screen, depending on the capabilities of the TV, set
4:3 OVERRIDE to 480i or 480p.
This may occur on a 16:9 TV if the active video for an SD broadcast is in letterbox
format. To confirm, wait for a commercial or look for a graphic, such as a network
logo. If the commercial fills the screen from top to bottom, or the graphic appears
below the active video, the program is being letterboxed by the broadcaster. You
can minimize this by activating the zoom feature on the TV.
A broadcast may include black bars on either side of a widescreen broadcast. This
is called a hybrid aspect ratio and results in a black border around the video on a
4:3 TV. Because this is part of the broadcast, the DCX3501-M cannot correct the
video. You may be able to minimize the border using the zoom feature on the TV.
Be sure to match up each signal to the same YPbPr connection on the TV.
Otherwise, colors will not appear correctly on the TV.
The DCX3501-M includes an integrated hard drive and a fan for cooling. During
normal operation, the DCX3501-M emits a low humming noise, similar to a
personal computer. The noise varies in volume occasionally when the speed of the
internal fan adjusts to changes in the temperature around the DCX3501-M. Please
note the hard drive will stay on even when the DCX3501-M is turned off (standby).
