Indicators, Warnings and Alarms
Start‐Up Indicator – The XPO
2
will turn On all lights briefly
and check for stuck buttons upon power up. It will then
output a brief audible beep when first turned On to indicate
the unit is operational.
Breath Detect Indicator ‐ The XPO
2
will put out a measured
pulse of oxygen each time it detects an inhalation. The blue
flow setting indicator light will blink each time an inhalation
is detected and the XPO
2
outputs a pulse of oxygen.
Internal Battery Charging Indicator – When the unit is not
turned On, but the AC, or DC, charger is connected to the unit
and providing power, the Battery Gauge Display will
sequentially illuminate each of the four segments. Periodically
the sequential illumination will be interrupted by the actual
battery charge display. If the unit is fully charged, all four
segments will be illuminated continuously until the unit is
turned On, or removed from charger power. If no Battery
Gauge Display segments are illuminated, the unit is not
charging. The lack of charging could be due to either a loss of
power, loose charger connections or the internal battery is not
at the proper temperature for charging. Allow the unit to
warm, or cool, to recommended charging temperature range
(see Recommendations for Optimal Performance on page 18),
check for loose connections and/or try a different power outlet.
