You may view this DVR using a standard 19” (or larger) VGA monitor or a television. The
former is connected using the VGA port on the back panel while the television utilizes the
BNC “Video Out” port on the back. Your DVR is configured to use the VGA port as the main
display. To use a TV, you will need to press and hold the STOP/ESC, EXIT or VGA/TV button
(depending on model) for approximately 10 seconds until you hear a beep indicating that the
video mode has been switched. A display connected to the other port will not show the menu.
