HW Ambient Failure
The hardware failure ambient alarm indicates that the
ambient sensor in the CAS200 is reporting that the
temperature around the scanner is outside of the
acceptable range of 0-50˚ C. This error can also occur when
there is a hardware failure.
If the scanner displays HW AMBIENT FAILURE:
1.
Check the ambient air temperature near the scanner.
Adjust ventilation, cooling or heating to ensure that
the temperature around the scanner is 0-50˚ C. If the
unit is functioning correctly, the error will clear
automatically when the ambient temperature is
within range.

If the ambient temperature is within range and the er-
ror persists:
a)
Turn n the power to the scanner off.
b) Remove the boards from the CAS200 housing.
c)
