If there are any required decompression stops, the next screen will

have the standard status line, but the second line now displays the

oxygen percentage of the diluent, deepest stop depth and stop time

followed by the total ascent time. The sample screen shows the deepest stop at 20fsw for two

minutes and a TTS of 12 minutes. This screen is displayed for approximately 2 seconds.

The final screen may seem like an annoyance, but it serves as a

reminder to the diver. The name of the diluent the diver has selected and

the programmed oxygen percentage of the diluent are displayed on the

second line. This should help insure that the diver doesn’t accidentally use a nitrogen only mix

with same oxygen percentage as a mix containing helium. This screen is displayed for

approximately 2 seconds.

STACK OVERRUN ALARM – ALL MODES

Once the programmed max stack time is exceeded, the secondary will turn on the

backlight for 5 seconds, indicate STACK OVERRUN on the display, flash the DIVA Red/Green,

Red/Green, and operate the buzzer in the DIVA twice. This alarm will recycle every TWO

MINUTES until it is cleared by reprogramming the max stack time to a greater value.
