Figure 2-12: 90385 Monitor Calibration menu

The Touchscreen Margin Adjustment/Settings menu provides preset settings to enable the

Biomed to tune a particular ring PCBA, IR lens, and I/O PCBA for optimal performance.

To adjust the CRT’s horizontal and vertical position (90385 only):

1. Touch the CRT POSITION key.

2. Verify that the CRT position adjustment keys appear (refer to Figure 2-12 on page 2-29).

3. Touch the adjustment keys as necessary to achieve the desired screen position and size.

The single arrow keys shift the raster in the indicated direction.

The double arrow keys expand (← →) or contract (→ ←) the raster image either horizontally or

vertically as indicated by the placement of the arrows (→ or ↑).

4. Touch the BORDER key to display a border around the display during adjustment.

WARNING:

• Normally, there should be no reason to adjust the factory defaults. Improper

adjustments or calibrations can SEVERELY degrade touchscreen

performance.

• If the display position is improperly set, the touchscreen will not align to the

display. If this condition occurs, shut off the monitor, enter two-finger diagnostics

(refer to

Extended Diagnostics on page 5-5) and set the screen position to mid-

range.
