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.

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

icon will flash, and the PO2 value with graphic PO2 will flash
(in place of NDC) until the Audible is silenced (Fig. 100, page
