Operating the Oximeter

Operator’s Manual
The levels in Table 5 are based on a new battery. As a battery is used and recharged over
time, it may provide only 75% capacity of a new battery. For example, a battery that is two
years old may provide only 75% (3 bars) of the capacity of a new battery.
Low Battery Indicator
Caution
Have a qualified service technician replace the internal battery every 24 months. The lead
acid battery is recyclable. Do not dispose of the battery by placing it in the regular trash.
Dispose of the battery in accordance with local guidelines or contact Nellcor’s Technical
Services department to arrange for disposal.
Caution
The pulse oximeter default settings return to factory default settings with a fully discharged
or replaced battery. Have a qualified service technician reset the oximeter to match the
institutional defaults, following the instructions in the
N-600x Service Manual .
Note:
If the AC voltage selector switch on the oximeter rear panel does not match your AC voltage
source, the oximeter may run on battery power, even though it is connected to an AC power
source, which eventually results in a low priority alarm and a lighted low battery indicator.
Ensure that the switch setting matches your AC voltage.
The Low Battery Indicator lights and a low priority alarm begins to sound when
approximately 15 minutes of monitoring time remain on the existing battery charge.
Refer to Table 5 for a description of the low and critical battery conditions. When the
battery capacity reaches a critically low battery condition, the Low Battery Indicator
flashes and a high priority alarm sounds for about ten seconds before the oximeter
shuts off.
Cancel a low battery audible alarm by pressing the ALARM SILENCE key. The low
battery indicator and display screen message continue to display. Silence the audible
alarm by connecting the oximeter to an AC power source. The low battery indicator
remains lit as long as the battery is in a low voltage condition.
If the oximeter backlight is turned off during a low battery condition, the backlight
cannot be turned back on until connected to an AC power source.
Note:
As the battery is used and recharged over time, the amount of time between the onset of the
low battery alarm and the oximeter shut-off may become shorter.
Indicates 14-38% (approx. 1-2.5 hours) battery
capacity remains.
Indicates 1-13% (less than 1 hour) battery capacity
remains.
