90364 Display Adjustments
Display Alignment
Ultraview 1600 uses a “display independent” concept. All setup for brighter/contrast and positioning
are set at the OEM display. Monitor controls have no effect.
If the 90364 Ultraview 1600 is used in conjunction with a 91416-B, configuration is the same as a
90363 Ultraview 1500.
All display adjustments for the 90364 are a function of the external display purchased separately.
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
The touchscreen calibration information is stored in the NVRAM of the 90364. If this information is
missing or has been changed, the 90364 will require that a calibration procedure be performed. 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 90364, may be calibrated in one of
three ways.
1. Initial Installation — If the 90364 does not have the touchscreen calibration information
stored in the NVRAM and the unit senses the presence of a touchscreen cable at the J9 port
during power-up, the 90364 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.
CAUTION:
• Do not interface with the monitor during automatic calibration.
