High Nitrogen Alarms

When nitrogen increases to the caution level (4 TLBG segments), 

the audible will sound during which time the TLBG segments will 

flash on the Main (Fig. 126).

In the event that nitrogen continues to increase and reaches the 

Deco level, the audible will sound again during which time all 

5 TLBG segments, the Up Arrow icon, and the graphic VIO (in 

place of Temperature), will flash, and NDC will display 0.

When the audible is silent, the TLBG and NDC digits are re-

moved.  The graphic VIO and Up Arrow icon flash (Fig. 127) 

until on the surface, then the Up Arrow is removed.  

The graphic VIO flashes until 1 minute elapses on the surface, 

then it alternates with FRE (Fig. 128) and operation reverts to 

Violation Gauge Mode for 24 hours.
