2. During a low battery condition, the LOW
BATTERY indicator LED will flash.
WARNING: When the LOW BATTERY INDICATOR
flashes, you must immediately replace the
device's batteries. Otherwise, the pulse
oximeter turns itself off about 30 minutes
after the indicator begins to flash.
Turning Off the Pulse Oximeter
The pulse oximeter powers down automatically
when not monitoring a patient (no finger in the
device). The unit will turn itself off in 8 seconds to
conserve battery power.
Checking the Monitor's Performance
Pulse oximeters do not require user calibration. If
checking the function of the device is desired, you
will need a compatible oximetry simulator that
provides a known SpO
oximeter. This will allow the oximeter's performance
to be checked.
