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.

2 [OPTIONAL STEP] By default, your sharpness and brightness adjustments are

applied equally to all of the video channels. However, if required, you can
select individual channels and adjust them separately.

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.

3 While viewing the displayed high contrast screen image, use the following

keys to adjust the controls:

Sharpness: for fine adjustment, for coarse adjustment.

There are 255 sharpness levels (one coarse step jumps 10 levels).

To autoset sharpness: Press to make the module calculate

and apply an automatic compensation level - you can use this as a

starting point for your fine tuning.
Note: If the monitor goes blank and switches off (due to
oversetting the sharpness adjustment) press the Home key to
restore.

Brightness: for adjustment. There are 255 brightness levels.
