3.2.1.3 Self-Test Screen
The unit automatically performs a built-in test (BIT) every time it powers
up. Important characteristics of this test are
• The self-test does not check the cables or sensors attached to those
cables.
• The Self-test screen displays directly after the user powers up the
unit, telling the user that the BIT is taking place. If there are no
problems, the Main Menu screen displays after a few seconds.
• If the BIT discovers any problems, see Section 6.4 “Troubleshooting”
on page 145 for details on troubleshooting.
