The internal, detachable, and external battery symbols that will 
display on the Monitoring screen are shown below. The detachable 
and external battery symbols will only appear on-screen if a 
detachable or external battery is attached to the device.

Internal Battery

Detachable Battery

External Battery

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.

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.
