Power Up
Power Prerequisites

Caution:
If any pixel in the monitoring screen does not light at power up, do not use
the monitoring system.

Caution:
During POST (immediately after power-up), confirm that all pixels in the
monitoring screen turn on and the monitoring system speaker sounds a
sequence of three ascending tones. After the POST process completes,
confirm that a single one-second tone sounds.
Before using the monitoring system in a clinical setting, ensure the monitoring
system is safe and working properly. Verify proper working condition at each
power up by following the directions for powering up the monitoring system.
To do so, carefully view the splash screen during power on. Verify there are no
black gaps on the monitoring screen during power-on self-test (POST) or when
every pixel on the screen is completely lit. Should users observe any black gaps
or unlit pixels, do not use the monitoring system before having the monitoring
system serviced.
Power-on Self-Test (POST)

WARNING:
Use the test data sheet to ensure the monitoring system passes all safety,
performance, and functional tests prior to use in a clinical setting.

WARNING:
Ensure the monitoring system is clear of any obstructions that prevent
awareness of visual or audible alarms. Failure to do so may result in
inadvertently missing a visual alarm or an inaudible alarm tone.

WARNING:
If the power-on self-test (POST) pass tone does not sound, do not use the
monitoring system. Instead, contact Covidien or a local Covidien
representative.
