The CompuMask will also enter a Violation Gauge Mode 5 minutes after surfacing from a
dive in which a Delayed Violation occurred.
Violation Gauge Mode on the Surface does not allow access to the SET F, PLAN,
FLY, and SAT features/screens.
The countdown timer that appears when you try to access the FLY screen does not repre-
sent Time to Fly. It is only provided to inform you of the time remaining before normal
operation can resume with full CompuMask features and functions.
In the event that a dive is made during the 24 hour period following the dive, a full 24
hour surface interval must then be served before all functions are restored.
