In order to set the oxygen fraction, access planning mode by pressing the “ mode ”
button and then the “ lock ” button. The fi rst value you will see is FO
2
, and you can
change it using the “ light/set ” button. Each time you press the button the oxygen
fraction increases by 1%.
The initial value is 21% (air), and you can set values up to (99%), and then the
cycles goes back to 21. To make it easier to set this value, if you hold down the
“
light/set ” button, the values scroll by faster, pausing briefl y at 32% and 99%.
If you do not set any value, Xtender shows “ - - ” in the display area reserved for
FO
2
, but if a value is entered, Xtender switches to Nitrox mode and the “ NX ”
icon activates.

When Xtender is in Nitrox mode and at a depth of more than 1.5 meters (5 feet), it
also indicates the oxygen partial pressure right above the “
NX ” icon.
