Display Adjustments (90387)
Display Alignment
All display adjustments (e.g., brightness, contrast, position) for the 90387 are a function of the OEM
display purchased separately. Monitor controls have no effect. However, the monitor can provide a
border to ease the performance of display alignments.
To display a border:
1. At the Main menu, touch MONITOR SETUP, and then touch PRIVILEGED ACCESS.
2. Enter the password using the on-screen keyboard and touch ENTER.
3. Touch the MORE key.
4. Touch SERVICE FUNCTIONS.
5. Touch MONITOR CALIBRATION.
6. Touch CRT POSITION.
The display will have a border around the screen perimeter. The current screen adjustment may be
such that portions of the border may be positioned off the screen. Adjust the position and size until
the entire border is visible and is positioned as close to the edge of the display as possible for
optimum display position.
Touchscreen Calibration
Touchscreen calibration information is stored in the monitor’s NVRAM. If this information is missing
or has been changed, a calibration procedure must be performed on the 90387. A touchscreen
calibration may also be performed if the touchscreen is not properly responding when a display key
is touched.
A remote monitor with touchscreen capability, connected to a 90387, may be calibrated in one of
three ways.
1. Initial Installation — If the touchscreen calibration information is not stored in the NVRAM
and the presence of a touchscreen cable at the J9 port is sensed during power-up, the
90387 will automatically display a calibration screen. The calibration screen will prompt the
user to touch the upper-left, upper-right, and lower-right corners of the display for calibration.
After calibration, the unit reverts to normal operating mode.
2. Recalibration using the Biomed menu — In the event the touchscreen becomes difficult
to use, it may need to be calibrated. To perform the calibration, attach a mouse (in the event
the touchscreen is unusable) and perform the following steps.
a. Power ON the 90387.
b. Touch the MONITOR SETUP key and then touch the PRIVILEGED ACCESS key.
c. Enter the Biomed code (the factory default is biomed).
d. Touch the MONITOR CALIBRATION key.
e. Touch the TOUCHSCREEN CALIBRATION key.
f. Touch the box displayed in the upper-left, upper-right, and lower-right corners of the
display.
