ALARM SILENCE
Audible alarms may be suspended, while visual alarms may not. With the exception of
Sleep Mode, there are two audible alarm suspension settings, all controlled by the Alarm
Suspend Button. Repeated pressing of the Alarm Suspend button will cycle though two
alarm suspend options.
Power-On – Alarms are active and Alarm Suspended Indicator is off.
Push Once – Alarm is suspended for 120 seconds and Alarm Suspended Indicator flashes
(See section 4 “Alarm features and sensitivity” to adjust alarm suspension time period).
Push Twice - Return to Audible Alarm Active.
ALARM SILENCED INDICATOR
The Alarm Silenced Indicator provides visual feedback when illuminated, the Rad-8 audible
alarms are muted.
While monitoring a patient, acknowledging an alarm condition by pressing the Alarm
Silence Button (one time) will silence the alarm tone for 120 seconds (default) and the
Alarm Silenced Indicator will flash. Pressing the Alarm Silence Button a second time
(while the Alarm Silenced Indicator is still flashing) will activate alarms and alarm silenced
indicator is off.
While not monitoring a patient, acknowledging an alarm condition by pressing the Alarm
Silence Button (one time) will permanently silence the alarm tone, and the Alarm Silenced
Indicator will remain illuminated until the power is cycled or patient monitoring begins.
While in the Home Mode and not monitoring a patient, the alarm will be suspended for
120 seconds (default).
Should the alarm condition be created by a low battery condition, plug the unit into AC
power immediately.

CAUTION:
TO ENSURE THAT ALARM LIMITS ARE APPROPRIATE FOR THE PATIENT
BEING MONITORED, CHECK THE LIMITS EACH TIME THE PULSE OXIMETER IS
USED.
An audible alarm and a flashing alarm status indicator will occur when an alarm limit is
exceeded for greater than five seconds (See section 4,
Alarm Features and Sensitivity
to
adjust this setting). It is best that the operator be within a minimum of 10 feet from the unit.
Directions for alarm suspension are indicated below. When a sensor is not connected to a
patient the “no sensor” indicator will illuminate. When a sensor is not connected to its cable,
“sensor off” indicator will illuminate. An audible alarm will accompany the visual indicator
unless the oximeter has been set to Alarm Suspend Mode.
