2
and pulse rate limit
alarms) and technical alarms (sensor condition, battery condition, internal
malfunction)
Visual alarm indicator, red/yellow LED
High priority alarm: red ON or red flashing ON/OFF
Medium priority alarm: yellow flashing ON/OFF
Visibility (operator positioned in front of monitor: 4 m (13 ft.) at 30° angle in any
direction

or pulse rate alarm limit is violated, the related
measurement flashes ON/OFF.
Audible alarm indicator: pattern varies according to alarm type and priority
Alarm Silence button: silences alarms for 2 minutes (press once; screen symbol is
displayed) or indefinitely (press 3 times; screen symbol flashes ON/OFF)
