Troubleshooting
These settings are used to troubleshoot any problems that
maybe occurring on the device. They provide various tests
to check the functionality of the system and identify
performance levels.
User Interface Tests
Use this option to run tests on the User Interface that will
help you diagnose screen problems. The following tests are available:
• User Interface Button Test enables the user to test the operation of all the hard buttons on the
control panel.
• Audio Tone Test enables the user to verify that the audible tone created by the user interface is
operating correctly.
• LED Indicator Test enables the user to verify that the lights on the user interface are operating
correctly.
• Touch Area Test enables the user to verify that the touch screen is operating correctly.
• Display Pixel Test enables the user to check that all the pixels that make up the display screen are
operating.
• Video Memory Test verifies that the memory used by the video controller on the user interface is
functioning correctly. Symptoms of memory failure are corrupted or non-functional screens on the
display.
• Communications Self Test tests the communication between the user interface and the main
control functions of the device. A communication failure will manifest itself as a corrupt or blank
display or an inoperative control panel.
• Reset UI to Factory Settings provides the facility to reboot or restart the software that controls
the user interface. Once the device has rebooted, the display will return to the default screen.
• Application Checksum Verification checks that the software used in the user interface is not
corrupt. Corrupt software may result in the user interface operating incorrectly.
To run each test, select Start Test and follow the instructions provided on the screen.
