WARNING

When the alarm sound is switched off, the equipment will give no audible alarm
tones even if a new alarm occurs. Therefore the user should be very careful
about whether to switch off the alarm sound or not.

Do not rely exclusively on the audible alarm system for patient monitoring.
Adjustment of alarm volume to a low level may result in a hazard to the patient.
Always keep the patient under close surveillance.
6.5.4 Adjusting Alarm Limits Automatically
The monitor can automatically adjust alarm limits according to the measured vital signs,
using the auto limits function. When auto limits are selected, the monitor calculates safe
auto limits based on the latest measured values.
To get accurate auto alarm limits, you need to collect a set of measured vital signs as a
baseline. Then, in the main menu, select [
Main ]
→
[ Alarm Setup>> ]
→
[ Auto Set ]
→
Select
[ Ok ] in the pop-up window. The monitor will create new alarm limits based on the
measured values.
Before applying these automatically created alarm limits, confirm if they are appropriate
for your patient. If not, you can adjust them manually.
The monitor calculates the auto limits based on the following rules.
