The amount of decompression Credit Time that you receive is
dependent on Depth, with slightly less Credit given the deeper
you are below the Stop Depth indicated.
You should stay slightly deeper than the Required Stop Depth
indicated until the next shallower Stop Depth appears. Then,
you can slowly ascend to, but not shallower than that indicated
Stop Depth.
DECO STOP MAIN DISPLAY (Default), information provided
includes (Fig. 78) -
> TLBG, all 5 segments indicating DECO.
> Graphic message DECO > STOP > xxF (or xxM),
scrolling, indicating the Stop Depth required.
> Current Depth with FT (or M) icon.
> Total Ascent Time (hr:min) with TIME and TAT icons.
> Stop Time (hr:min) required with STOP and TIME icons.
> Nx icon, if FO2 is set for Nitrox.
 Press/release the A button (< 2 sec) to view the Deco Stop
ALT 1 screen.
TAT (Total Ascent Time):
TAT (Fig. 78a) includes Stop Times required at all required
DECO Stop Depths plus vertical Ascent Time calculated at 60
FPM (18 MPM) for depths deeper than 60 FT (18 M), and 30
FPM (9 MPM) for depths of 60 FT (18 M) and shallower.
