Connected devices usually take their power from the monitor. External devices such as gas monitors
and those connected via VueLink/IntelliBridge have their own power switches.
Power On/Power Off Behavior
The general rules determining the behavior of the monitor when connected to, or disconnected from
power are as follows:
• A monitor that was switched on prior to a temporary power loss switches on again when power is
restored.
• A monitor that was switched off prior to a temporary power loss remains off when power is
restored.
• When AC mains power is lost, a battery powered monitor continues to run without interruption
on battery power.
• An MMS switches on automatically when connected to a running host monitor.
• When an X2 is disconnected from a running host monitor, the X2 continues to run without
interruption on battery power.
Starting Monitoring
After you switch on the monitor,
1 Admit your patient to the monitor.
2 Check that the profile, alarm limits, alarm and QRS volumes, patient category and paced status and
so forth are appropriate for your patient. Change them if necessary.
3 Refer to the appropriate measurement chapter for further details of how to perform the
measurements you require.
WARNING
During MR imaging, remove all transducers, sensors and cables from the patient. Induced currents
could cause burns.
Disconnecting from Power
The On/Standby switch does not disconnect the monitor from the ac power source. To disconnect,
unplug the power cable.
Monitoring After a Power Failure
• A monitor that was switched on prior to a temporary power loss switches on again when power is
restored.
• A monitor that was switched off prior to a temporary power loss remains off when power is
restored.
If the monitor is without power for less than one minute, monitoring will resume with all active
settings unchanged.
If the monitor is without power for more than one minute, the behavior depends on your
configuration.
