Monitor Setup

Control Dial Definitions

The Control Dial on the right side of the monitor provides control to navigate and select menu entries. The main menu is invoked when the Control Dial is pressed in momentarily (i.e. < 1 second). When the Control Dial is rotated UP or DOWN and the menu is active, the position of the menu item to be selected is incremented or decremented by one. Pressing the Control Dial in monentarily causes the viewed item to be selected. Selected items can be either a menu item or a setup parameter. Parameters become stored and effective upon exiting the main menu.

Monitor Default Values

Initially set the monitor parameters to PercuVision® recommended values. Only two parameters need to be changed from the factory default values.
Black Level = 70
Video Source = Composite
The Black Level can only be set when video is detected (LED = GREEN). The Video Source can be assigned to Composite independent of the Video Detect State (LED = ORANGE or LED = GREEN). If for some reason the display monitor becomes suboptimal, reset the monitor to default values and then define video source to be Composite and increase Black Level to 70. If still suboptimal, call customer support.
