The depth alarm is factory-set to 40 m/131 ft, but you can adjust it according to your

5.8.2. Setting the dive-time alarm

The Suunto D6 has a dive-time alarm setting which, when activated, can be used for
several purposes to add to your diving safety.
NOTE

5.8.3. Setting the nitrox values

If set to the NITROX mode, the correct oxygen percentage of the gas in your cylinder
(and additional gases) must always be entered into the computer to ensure correct
nitrogen and oxygen calculations. In addition, the oxygen partial pressure limit must
be set. When in the Nitrox setting mode, the equivalent allowed maximum depth,
based on the chosen setting, will also be displayed. Settings for an additional mix
(MIX2) are made similarly, but with the additional selection of "ON" or "OFF".
