VGM ON SURFACE

The graphic VIOL flashes for the first 10 minutes, then it alter-

nates with NORM (each On 3 seconds, Fig. 99A/B) until DC 

shut down after 24 hours with no dives.

In the event that a dive is made during the 24 hour period, 

a full 24 hour surface interval must then be served before all 

functions are restored.

During that 24 hours, VGM does not allow access to the Set F, 

Plan, Dsat, and FREE Mode features/screens.  All Watch and 

Compass functions will be allowed.  

The Fly countdown timer provides the time remaining before 

normal operation can resume with full features and functions.

HIGH PO2

Warning >> at Alarm Set Point value minus .20 (1.00 to 1.40)

Alarm >> at Set Point value, except in Deco then at 1.60 only

When partial pressure of oxygen (PO2) increases to .20 less 

than the PO2 Alarm Set Point; the Audible sounds, the Up Arrow 

icon will flash, and the PO2 value with graphic PO2 will flash 

(in place of NDC) until the Audible is silenced (Fig. 100, page 

109).
