Chapter 5: Alarms and Messages
The following chapter contains information about alarms and messages.
Alarm Indication
An alarm condition is indicated by an audible alarm tone and visual alarm indicator.
Sensor condition, system failure and low battery alarms.
“SEn OFF” and “nO SEn” will only generate an alarm condition after a pulse has
been found.
Rad-5 only: Audible and visual alarms for high low saturation and pulse rate
(SpO
2
range 1-100%, pulse rate range 25-240 bpm).
The following table shows the potential result of failure to respond to the cause of the alarm

Low Battery Audible Alarm
All four indicators will be lit when the batteries are full, with fewer indicators being lit as the
batteries lose their charge. See
Battery Level Indicator
on page 26. When less than ten (10)
percent battery life remains, the final battery indicator will begin to flash and an audible
alarm will sound.
If a low battery condition occurs during patient monitoring, a low priority alarm
will sound, and can be silenced for 120 seconds by pressing the Alarm Silence
Button.
