These keys can be used to move the display up, down, left, and right as well as to stretch or
compress the display horizontally and vertically.
Touch the Border key for a border to appear around the screen perimeter; however, the current
screen adjustment may be such that portions of the border may be positioned off-screen. Adjust the
screen position and the size until the entire border is visible and is positioned as close to the edge of
the display as possible. This is the optimum screen position adjustment.
Display Color
To inspect the color:
1. Power OFF the monitor for several seconds and then power ON again.
2. Enter the Boot menu when the 3-2-1 countdown appears on the System Startup screen
(refer to
Troubleshooting on page 5-1 for detailed instructions).
3. At the Boot menu, touch D for diagnostics, then i for individual diagnostics, v for video
diagnostics, and i for the interactive video diagnostic. After displaying several messages, the
entire screen will cycle through the colors of red, green, blue, white, and black, pausing for
five seconds at each color.
4. Inspect the screen to verify that all the colors appear and that no portion of the display is
discolored or exhibits other undesirable visual flaws.
5. If discoloration or other flaws are evident, press v for video diagnostic. If the diagnostic
passes, return the entire monitor to Spacelabs Medical for service. If the diagnostic fails,
refer to
Monitor Fails Power-ON Diagnostics on page 5-5 for suggested service action.
Touchscreen Calibration
In the event the touchscreen becomes difficult to use or a replacement has been installed, you may
need to calibrate it. This can be performed by using the calibration function found under the Biomed
menu.
To perform the calibration, attach a mouse (in the event the touchscreen is unusable) and
perform the following:
1. Power ON the 90363.
2. Touch MONITOR SETUP and then touch PRIVILEGED ACCESS.
3. Enter the Biomed code (the factory default is Biomed).
4. Touch MONITOR CALIBRATION.
CAUTION:
• Repositioning the screen does not change where the IR touchscreen
expects each key to appear. If the screen size or position is severely altered,
significant misalignment of the key images and the true physical
touchscreen keys may occur.
!
• The display color can be inspected, but the monitor must be returned to
Spacelabs Medical for adjustment.
