6.6 CHECKING THE BATTERY STATUS WHEN INSTALLED ON THE DEVICE
When operating on battery, the display will show the estimated percentage (%) or minutes of charge
remaining. These icons indicate the device is operating on battery power and is not charging:
Battery is full.
Battery has approximately 40% to 50%
charge remaining.
IMPORTANT: When the device detects that the battery has less than 10 minutes remaining, a low priority
alarm will sound. When the battery is empty, the alarm will change to a higher priority.
When the battery has less than 10 minutes remaining, do one of the following:
• Plug the device into an AC or DC power source using the AC power supply or DC power cable.
• Turn off the device and replace the depleted battery with a charged battery. To remove the battery,
press and hold the battery latch button and slide the battery off the device.
If the battery is drained, charge the battery by plugging the device into external power or charging it with
the external battery charger.
6.7 CHECKING THE BATTERY STATUS WHEN NOT INSTALLED ON THE DEVICE
• To check the battery charge when it is not installed in the device, press the green battery icon button.
The battery gauge indicator lights (<10% - 100%) will illuminate to the left of the green battery icon
button to indicate the level of the battery pack charge:
• 4 LEDs light up: 75% to 100% full
• 3 LEDs light up: 50% to 75% full
• 2 LEDs light up: 25% to 50% full
• 1 LED lights up: 10% to 25% full
• 1 LED Blinks: Battery is less than 10% full
and needs to be recharged
6.8 CHARGING THE BATTERIES WITH THE CONCENTRATOR
The concentrator will recharge the battery any time the battery is installed and the device is connected to
an external AC or DC power source (except on an airplane). You will know the battery is charging when the
battery icon on the device's display has a lightning bolt going through it as shown:
The battery is fully charged and is charging
as necessary to maintain its charge.
Battery is charging with charge level less
than 10%.
When starting to charge a fully drained battery, the charging process may start and stop during the first
few minutes. This is normal.
Leaving your device plugged in past the full charge time will not harm the device or the battery. If using
multiple batteries, make sure that each battery is labeled (1, 2, 3 or A, B, C, etc.) and rotate on a regular
basis.
