AMPHOS DC MANUAL
© 2002 Design, 2012 Doc. No. 12-5301-r01 (12/17/12)
VIOLATION GAUGE MODE (VGM)
If calculations require a Deco Stop Depth greater than 70 FT (21 M), operation will enter Violation Gauge Mode (VGM) for the
remainder of that dive and for 24 hours after surfacing.
The AMPHOS will also enter VGM if Deco is entered while operating in FREE Mode (described later).
VGM turns the AMPHOS into a digital instrument without any nitrogen or oxygen calculations or monitoring functions or dis-
played information until 24 contiguous hours elapse on the surface with no dives.
VGM Main, information includes (Fig. 81) -
> Up Arrow icon with graphic UP, flashing until on surface then removed.
> Elapsed Dive Time (hr:min) with DIVE icon.
> Current Depth with FT (or M) icon.
> Gas (tank) icon, Gas in use (1 or 2).
> NX icon, if either gas is set for Nitrox.
> Full NIBG with N2 icon, flashing while audible sounds then removed.
> ASC, while ascending.
• A (< 2 sec) to view ALTs (similar to those for No Deco).
• M (2 sec) to access the Gas Switch Preview.
• S (< 2 sec) to acknowledge/silence other alarms.
• L (press) to activate Backlight.
The AMPHOS will also enter VGM 5 minutes surfacing from a dive in which a Delayed Violation (1, 2, or 3), or 100% O2 condi-
tion occurred.
Once on the surface, VGM does not allow access to the Set F, Plan, and Desat 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. 82) -
> Graphic Vio during the first 10 minutes, then alternating with Nor for 24 hours.
> Number of recent dive completed with DIVE icon.
> Surface Interval Time (hr:min) with SURF icon.
> Tank icon (1 or 2) representing the Gas in use, default to #1 after 10 minutes.
> Battery icon if a Low Battery condition exists.
• A (2 sec) will access NORM SURF ALT.
• A (< 2 sec) will access Log Mode, then again History.
• A + S (2 sec) will access the Set Modes.
• M (2 sec) will access GAUG Surface Main, then another 2 seconds FREE Surface Main.
• M (< 2 sec) will revert to Watch Default Time.
• S (< 2 sec) will access the Time to Fly countdown screen*.
• L (press) will 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
Warning at 0.20 (ATA) less than the PO2 Alarm value set*.
Alarm at the value set*.
*While in Deco, High PO2 will only alarm at 1.60 (no warning).
When PO2 increases to the Warning level, the audible will sound until acknowledged or time out during which the graphic UP
and Up Arrow icon will flash and the graphic PO2 value with PO2 icon will flash on the Dive Main in place of Depth (Fig. 83).
After the audible is silenced, Depth will be restored, while the graphic UP and Up Arrow icon will remain on solid (Fig. 84) until
PO2 decreases below the Warning level when they will be removed.
When PO2 reaches the Alarm level, the Audible will sound again and information will be displayed as indicated above with the
exception the PO2 value will alternate with Depth until it decreases below the Alarm level.
• S (< 2 sec) to acknowledge/silence the Audible.
• A (< 2 sec) to view ALTs.
• M (2 sec) to access the Gas Switch Preview.
• L (press) to activate Backlight.
