Displays, Indicators and Controls
Pulse Strength Bargraph LED
This 8-segment tricolor bargraph indicates pulse strength as
determined by the oximeter. The height of the Pulse Strength
Bargraph LED is proportional to the pulse signal, and the color
is determined by pulse strength:
Alarm Silence LED
This amber LED indicates that the audible alarm is silenced for
two minutes when it blinks. When alarms are active, this LED
blinks in time with the alarm bar. If no alarms are active, this
LED flashes at the medium priority alarm rate. When lit solid,
the Alarm Silence LED indicates that audible alarm volumes are
set to less than 45 dB.
AC Power Adapter LED
This green LED is displayed when an external power supply is
providing power to the Model 7500FO.
Low Battery LED
This amber LED indicates a low battery charge when blinking,
and a critical battery charge when lit solidly. This LED does not
indicate that the Model 7500FO is running on battery power.
WARNING:
This device turns off after approximately 30 minutes when in
low battery mode.
