DECOMPRESSION STOP MAIN
Decompression (deco) Stop Main will display upon ascending to within 10 ft (3 m) below the Decompression Stop depth. The full stop graphic (op-
posed arrows with stop icon) will be displayed solid. While Decompression Stop Main is displayed, you may access up to 3 ALT displays by pressing
the SELECT button to cycle through them. They are similar to the No Decompression Main, Dive ALT 1, and Dive ALT 2 displays, respectively.

CONDITIONAL VIOLATION (CV)
Upon ascent above the required Decompression (deco) Stop depth, operation will enter Conditional Violation during which time no off gassing
credit will be given. The Audible alarm will sound and the alarm LED will flash. The full Tissue Loading Bar Graph and down arrow will flash until the
audible alarm is silenced, then the Tissue Loading Bar Graph will be solid.
• The down arrow continues to flash until descending below the required Stop Depth (within stop zone), then the full stop graphic (opposed arrows
with stop icon) will be on solid.
• If you descend deeper than the required Decompression Stop before 5 minutes elapse, Decompression operation will continue with no off gassing
credit given for time above the Stop. Instead, for each minute above the Stop 1½ minutes of penalty time will be added to the required Stop Time.
• The added penalty (decompression) time will have to be worked off before obtaining off gassing credit.
• Once the penalty time is worked off, and off gassing credit begins, required Decompression Stop Depths and Time will decrease toward zero. The
Tissue Loading Bar Graph will recede into the No Decompression zone, and operation will revert to No Decompression mode.

DELAYED VIOLATION 1 (DV 1)
If you remain shallower than a Decompression Stop Depth for more than 5 minutes, operation will enter DV1* which is a continuation of CV with
penalty time still being added. Again, the audible alarm will sound and the full Tissue Loading Bar Graph will flash until it is silenced. ALT screens are
accessed and appear similar to Decompression ALT screens.
*The difference is that 5 minutes after surfacing from the dive, operation will now enter Violation Gauge Mode.
• The down arrow continues to flash until descending below the required Stop Depth, then the full stop graphic will be on solid.
• If the DV1 status is ignored, the GEO AIR will enter DV1 Surface mode for 5 minutes upon surfacing from the dive. The down arrow, Decompres-
sion Stop depth/time, and Surface Time will be displayed. After 5 minutes on the surface in DV1 mode, the unit will enter VGM (Violation Gauge
Mode).
