VIOLATION GAUGE MODE (VGM)
If calculations require a Deco Stop Depth greater than 70 FT (21 M), or if Deco is entered while operating in FREE Mode (de-
scribed later), operation will enter Violation Gauge Mode (VGM) for the remainder of that dive and for 24 hours after surfacing.
VGM turns the Talis into a digital instrument without any nitrogen or oxygen calculations or monitoring functions or displayed
information until 24 contiguous hours elapse on the surface with no dives.
VGM Main, information includes (Fig. 69):
> Graphic VIO, flashing until the audible is silenced then solid.
> EDT (hr:min) with wave/clock icon.
> Tank icon, Gas in use (1 or 2).
> Current Depth with FT (or M) icon.
> Up Arrow icon, flashing until on surface.
• A (< 2 sec) - to view ALT screens (similar to those for No Deco).
• M (2 sec) - to access the Gas Switch Routine.
• S (< 2 sec) - to acknowledge/silence alarms.
• L (press) to activate Backlight.
Operation will also enter VGM 5 minutes surfacing from a dive in which a Delayed Violation (1, 2, or 3) occurred.
Once on the surface, VGM does not allow access to the Set Gas, Plan, Fly, and Dsat features/screens.
This condition is a Permanent Violation, and 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.
VGM Main (on surface), information includes (Fig. 70):
> Surface Interval Time (hr:min) with clock/wave icon.
> Graphics Vio and Nor, alternating for 24 hours.
> Tank (Gas 1) icon.
> Dive number with # icon.
> Battery icon if low battery condition.
• A (2 sec) - to access SURF ALT.
• A (< 2 sec) - to access Log Mode, then History.
• A & S (2 sec) - to access Set modes.
• M (< 2 sec) - to revert to the Watch Default Time screen.
• S (< 2 sec) - to access Time to Fly*, Plan mode is bypassed.
• L (press) - to activate the Backlight.
*The countdown timer that appears when you access Fly is only provided to inform you of the time remaining before normal
Dive Computer operation can resume with full features and functions.
HIGH PO2
When partial pressure of oxygen (PO2) increases to 0.20 (ATA) less than the PO2 Alarm value set for the Gas in use*, the
Audible will sound.
> The graphic PO2 and Up Arrow icon will be displayed flashing on the Main (Fig. 71) until the Audible is silenced, then
the graphic PO2 will alternate with NDC time if in No Deco (Fig. 72), or TAT if in Deco, until PO2 decreases to 0.20 (ATA)
below the alarm value set.
> The current value of PO2 can be viewed on the No Deco ALT 2, or Deco ALT 3, screen.
• S (< 2 sec) - to acknowledge/silence the Audible.
• A (< 2 sec) - to view ALT screens.
• M (2 sec) - to access the Gas Switch Routine.
• L (press) - to activate the Backlight.
> When PO2 reaches the Alarm value set for the Gas in use, the Audible will sound again.
> The Up Arrow icon will flash on the Main screen until PO2 decreases 0.20 (ATA) below the alarm setting.
