Low Air Pressure Warnings
The dive computer will warn you with three audible double beeps and a blinking
pressure display when the cylinder pressure reaches 50 bar/725 psi.
Three double beeps are also heard when the cylinder pressure goes down to the user-
selected alarm pressure and when the remaining air time reaches zero.

6.1.4. Ascent rate indicator

The ascent rate is shown graphically along the right side of the display. When the
maximum allowed ascent rate is exceeded, the fifth SLOW warning segment and the
STOP sign appear and the depth reading starts to blink, indicating that the maximum
ascent rate has been exceeded continuously or that the current ascent rate is
significantly above the allowed rate.
