3.3.3 Turning off the Monitor 
Before turning off the monitor: 
1.  Confirm that the monitoring is finished. 
2.  Disconnect patient cables and sensors from the patient. 
3.  Make sure to save or clear the patient monitoring data as required. 
 
Press and hold the power on/off switch for above 2 seconds to turn off monitor. 
 
CAUTION 
  Although not recommended, you can press and hold the power on/off switch 
for 10 seconds to forcibly shut down the monitor when it could not be shut 
down normally or under some special situations. This may cause data loss of the 
monitor.  
  The monitor restores the latest configuration if restarts within 60 seconds after 
the power failure. And it will restore the default configuration rather than the 
latest configuration if restarts 120 seconds later after the power failure. The 
monitor may load either the latest configuration or the default configuration if 
restarts from 60-120 seconds after the power failure. 
  Power failure may cause data damage on SD card. It is recommended to turn off 
the monitor according to the normal procedures. Do not directly unplug the 
power cord
, unless there is a charged battery installed, or remove the battery 
before shutting down the monitor.
