to enter configuration mode.
The three keyboard indicators (‘Num Lock’, ‘Caps Lock’ and ‘Scroll Lock’) will now begin to flash in sequence. The speed of the sequence indicates the
level of the sharpness adjustment currently applied: the slower the rate, the lower the level of sharpness being applied.

To select video channels: Using the numeric keys of the main keyboard (not the keypad keys), press the number of the video channel to adjust. When a numeric key is pressed, all three of the keyboard indicators will illuminate for a moment before continuing with their flashing sequence.
3While viewing the displayed high contrast screen image, use the following keys to adjust the controls:
Sharpness:
