DECOMPRESSION DIVE MODE
The GEO is designed to help you by providing a representation of how close you are to entering Decompression.
Decompression Dive Mode activates when the theoretical No
Decompression time and depth limits are exceeded.
Upon Entry into DECO Mode, the Audible Alarm will sound, | Fig. 76 - DECO ENTRY |
the red LED Warning Light will flash, and the graphic message DECO > STOP will scroll each 3/4 second On and 1/4 second Off, until acknowledged or for 10 seconds.
Once silenced, the graphics DECO > STOP > xxF (or xxM) will scroll each 2 seconds On 2 seconds blank.
•Press/release the S button to acknowledge/silence the Audible Alarm (unless it was set Off).
•The UP Arrow will flash (Fig. 76) if you are greater than 10 FT (3 M) deeper than the Required Stop Depth.
•Once you are within 10 FT (3 M) of, and below, the Required Stop Depth, the UP Arrow will extinguish.
Managing Decompression Stops
To fulfill your decompression obligation, you should make a safe controlled Ascent to a depth slightly deeper than (Fig. 77a), or equal to, the Required Stop Depth indicated (Fig. 77b) and decompress for the Stop Time indicated (Fig. 77c).
