NORMAL OPERATION INDICATORS
During normal operation, the Control Panel and Display Screen 
should appear as described below:
OPERATION
DESCRIPTION
Active or Rest Mode
Activitated
The	word	“Active	Mode”	or	“Rest	Mode”	will	appear	next	to	your	selected	
pulse	setting.	If	“Active	Mode”	is	displayed	it	means	your	breath	rate	is	typical	
for	an	active	user.	If	“Rest	Mode”	is	displayed	it	means	your	breath	rate	is	
slower than your normal active breath rate. 
Alarm Muted
The audible alarm signal will be muted and the Mute symbol will 
display on screen. The red alarm LED will remain illuminated on the 
Control Panel and the alarm title will remain on the display. 
Breath Detected
The PULSE-WAVE Breath Detection Symbol will flash as you breathe. This 
is confirmation the device is delivering a dose of oxygen with each inhaled 
breath. 
If you stop breathing through the nasal cannula (mouth breathing), the unit 
will begin delivering doses of oxygen automatically without the PULSE-
WAVE	symbol.		After	75	seconds,	the	unit	will	provide	a	“NO	BREATH	
DETECTED”	alarm	and	will	continue	to	automatically	provide	doses	of	
oxygen until normal breathing resumes. When the unit detects normal 
breathing,	the	“NO	BREATH	DETECTED”	alarm	will	cease	and	the	PULSE-
WAVE symbol will indicate detection of your breath.
Charging Status
The following messages will appear on the display depending on the battery 
being used or charged.
“Charging	Internal”	means	the	Internal	Battery	is	charging.
“Charging	External”	means	the	External	Battery	is	charging.	
“Running	Internal”	means	the	Internal	Battery	is	in	use.
“Running	External”	means	the	External	Battery	is	in	use.
NOTE:  By design, the device will preserve the Internal Battery charge as 
long as possible. This means that the External Battery will deplete before the 
Internal Battery and the Internal Battery will charge before the External Battery 
when connected. 
Connected to Activox DUO2 When the device is connected to the Activox DUO2 stationary base, the Display
Screen will show the message “Connected to Activox DUO2”.
Power Interruption
The device will emit a two second audible tone if the AC or DC Power is 
interrupted or intentionally unplugged. The unit will automatically switch 
to battery operation. If the power was not intentionally removed, check all 
connections between the unit and the power source to ensure all are secure 
and firmly plugged in. If the power indicator icon does not show on the 
display, switch to another power source (AC or DC) or source of oxygen and 
contact your equipment provider. 
Powered On
The Power Indicator is illuminated green and the Display Screen is on.
Setting Selected
“1”, “2”, “3” or “4” will appear under “Setting” on the Display Screen.
