Indicators
Pulse Quality LED Indicator
Located above the On/Off button, this tricolor indicator blinks once for each
detected pulse and changes color with the pulse strength signal:
•
Green
indicates a good pulse strength.
•
Amber
indicates a marginal pulse strength. To improve signal quality,
reposition the sensor, try a different sensor type, eliminate animal movement,
or improve the site’s circulation.
•
Red
indicates an inadequate pulse strength. When the Pulse Quality indicator
is red, SpO
2
and pulse rate values are not updated. After 10 seconds, the
values are replaced with dashes, indicating that readings are not possible.
Low Battery LED Indicator
This amber indicator flashes to indicate a low or critically low battery. It is a medium
priority alarm.
When batteries are critically low, the digital displays go blank and the Pulse Quality
indicator blinks amber or red. Any SpO
2
or pulse rate alarms in effect when
critically low battery capacity is reached are latched, and flashing dashes appear
on the corresponding display. After 10 minutes at critically low battery capacity, the
pulse oximeter automatically shuts off.
Alarm Silence LED Indicator
Located left of the On/Off button, this amber indicator blinks when all audible
alarms are temporarily silenced. If the alarm volume is set to OFF, the Alarm
Silence indicator is solidly lit.
Alarm Bar LED Indicator
Located near the top of the device, this indicator flashes:
•
Amber
during medium priority alarms
•
Red
during high priority alarms
Audible Indicators
The pulse rate tone beeps for each detected pulse. This beep changes in pitch with
SpO
2
values. The default volume is OFF. During normal operation, the volume can
be changed by momentarily pressing the Advance button.
Audible alarms also sound for high and medium priority alarms. See “Alarms” for
more information.
