Furthermore, you can experience following alarms: 

•

 

PO2

 – is triggered if the gas you are breathing, at your current pressure, has either lower PO2 

than your 

Min PO2

, or higher PO2 than:

 

o

 

PO2 dive

, if this gas is configured as Dive Gas

 

o

 

PO2 deco

, if this gas is configured as Deco Gas

 

o

 

Both

 

PO2 dive

 

and

 

PO2 deco

, if this gas is configured as Backup Gas or Custom Gas

 

•

 

END

 – it is triggered is gas you are breathing, at your current pressure, has higher END than 

than your configured 

Max END

 

•

 

OTU

 – if you have exceeded your OTU limit, within the last few days (refer to 

Oxygen loading

 

section to learn more about how XEO computes those limits)

 

•

 

CNS

  –  if you have exceeded your CNS limit (refer to 

Oxygen  loading

  section to learn more 

about CNS tracking)

 

 

Each of the above alarms is displayed as a 
Blinking Gas Label, alternating with the red 
label of the alarm (“PO2”, “END”, “CNS”). If 
more than one of them is on, they will alternate 
as well. 
 

 

 

 

The current temperature of the surrounding environment is displayed in the 
lower-left-hand corner, next to the battery indicator. 

Temperature 

 
It is displayed either in Celsius or in Fahrenheit, depending on your Units 
setting (refer to the “

Units

” section of the manual for details). You will see 

a “C” or “F” letter next to the temperature value to let you know which 
units you have selected. 

  

 
Keep in mind that the temperature sensor is inside the XEO unit, so it may take a moment for it to 
adjust to a rapid external temperature change.  
 
The XEO will function when its internal temperature is between -  0 to 40°C (32 to 104°F). If the 
XEO’s internal temperature exceeds 40°C/104°F  (in direct sunlight, for example) the OLED display 
could show some visual disturbances. This is not a product failure – the display will return to normal 
when the unit is cooled down.
