System Failure (medium priority)
The MCH software constantly monitors the internal systems for problems. If a serious problem is
detected, the MCH will halt its operation, the alarm will sound a repeating three-beep sequence
every 8 seconds, and the FAILURE screen will appear. The MCH subsystem that caused the
failure will be marked by a red "X" in the TEST STATUS column. Touching the "Status Reset"
button (bottom right) will reset the alarm and cause the MCH to retry the system test sequence. If
the system test is successful, the alarm will clear and the TESTING screen will appear, with
green checkmarks in the TEST STATUS column. Otherwise, the FAILURE screen will remain,
and the alarm will continue to sound. To mute the alarm for 60 seconds, touch the Audio Silence
button at the bottom left corner of the screen.

If the FAILURE screen is accompanied by this
TEMPERATURE DIFFERENTIAL ERROR notice,
check all hose connections, valves, and connected
equipment in the water circuit for blocked flow. Once
the water path is confirmed to be clear, touch the
Status Reset button to clear the alarm, then return to RUN mode.
If the FAILURE screen appears repeatedly, this may indicate a serious problem with your
MCH unit that could affect patient and operator safety. Even if the system returns to normal
operation after a system test or a power cycle, please contact CardioQuip for troubleshooting
assistance and, if necessary, to schedule a service call.
Audio Silence
When an audible alarm is silenced, the Audio Silence indicator is displayed on
all operation screens. If the alarm issue remains unattended, the audible alarm
will resume after 60 seconds.
