There are several DC power indicators that will display on the
Monitoring screen to indicate which battery is in use (if applicable), if
the batteries are low, charging, or discharged, etc. The following table
explains all of the DC power indicators.
DC Power Indicator Description
Battery In Use Indicator A black box will appear around the battery that is in use. For instance, if
the external battery is currently in use, the symbol appears on the
Monitoring screen.
Green Fully Charged
Battery Indicator
When a battery is charged to greater than 90% of its capacity, all of the
bars in the battery symbol will appear in green.
Partially Charged
Battery Indicator
When a battery is partially charged, some of the bars in the battery
symbol will appear in green, while others will be clear. For instance, if
the external battery is 50% charged, the following symbol displays on-
screen:
Yellow Low Battery
Indicator (Medium
Priority)
When the device detects that an in-use battery’s charge is low (has
approximately 20 minutes of charge left), the inside of the box
surrounding the battery symbol turns yellow. (In addition to the
battery indicator on the Monitoring screen, a medium priority alarm
message will display indicating “Low Battery.” See Chapter 6 for more
information. The yellow indicator is for the last available battery source.
Note: Under normal operating
conditions, the internal battery
symbol will always display on
the Monitoring screen. If the
symbol appears as an empty
red battery on your screen,
contact Philips Respironics
or an authorized service
representative to have your
device serviced.
