Low Battery Indicator
The Low Battery Indicator lights and a low priority alarm begins to
sound when approximately 15 minutes of monitoring time is
available on the existing battery charge. Refer to Table 4 for a
description of the low and critical battery conditions.
A low battery audible alarm can be cancelled by pressing the
ALARM SILENCE button. The low battery indicator and display
screen message continues to display. Connecting the monitor to an
AC power source silences the audible alarm, but the low battery
indicator remains lit as long as the battery is in the low voltage
condition. After the 15-minute period of low battery condition, a high
priority alarm sounds for about 10 seconds before the monitor shuts
off.
If the monitor backlight is turned off during a low battery condition,
the backlight cannot be turned back on.
Nellcor recommends that a qualified service personnel replace the
internal battery every 24 months. Replaced batteries should be
disposed of in accordance with local ordinances.
Caution: The pulse oximeter default settings will return to
factory default setting if the battery becomes fully discharged or
is replaced. Qualified service personnel will have to reset the
institutional defaults, following the instructions in the
N-600x Service Manual.
Note : If the AC voltage selector switch on the monitor rear panel
does not match your AC voltage source, the monitor 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.
Note : As the battery is used and recharged over time, the amount of
time between the onset of the low battery alarm and the instrument
shut-off may become shorter.
