Diagnostic self-test
During this time the system performs a diagnostic self-test (electronics,
battery status, analog signal path integrity, calibration check) and sets the
default parameters. This self-test takes approximately 10 seconds.
•
A start-up tone sequence tests the audio circuit; all display LEDs and
the LCD backlight are illuminated, then blanked.
•
The alarm LED toggles between red and yellow while a numeric
countdown from 9 to 0 occurs on each seven-segment LED display
ending with a decimal point.
•
A battery icon is displayed to indicate the battery condition as either
charged, depleted, or defective/missing (see chapter 3).
Upon successful completion of all diagnostic self-tests, the unit is
considered to be in calibration and begins normal operation. This message
is displayed:
Test passed. In calibration.
If the unit does not pass the self-test, an error message is displayed and the
unit is inoperable.
