Suunto D6I manual Low Air Pressure Warnings

The change in your air consumption is based on constant one second interval pressure measurements over 30–60 second periods. An increase in air consumption influences the remaining air time rapidly, while a drop in air consumption increases the air time slowly. In this way, an over optimistic air time estimation, caused by a temporary drop in air consumption, is avoided.

The remaining air time calculation includes a 35 bar/500 psi safety reserve. This means that when the instrument shows the air time to be zero, there is still about 35 bar/500 psi of pressure left in your cylinder, depending on your air consumption rate. With a high consumption rate, the limit will be closer to 50 bar/700 psi and with a low rate closer to 35 bar/500 psi.

NOTE

NOTE

Filling your BC affects the air time calculation due to the temporary increase in air consumption.

The remaining air time is not displayed when either deep stops or the decompression ceiling have been activated. You can recall the remaining air time by long-pressing the DOWN button, but the ceiling disappears.

NOTE	A change of temperature will affect the cylinder pressure and
	consequently the air time calculation.

Low Air Pressure Warnings

The dive computer will warn you with three (3) audible double beeps and a blinking pressure display when the cylinder pressure reaches 50 bar/700 psi.
