Decompression Dive Mode (DECO) is entered when nitrogen calculations determine that you cannot
safely surface without stopping at a predetermined depth to allow off gassing of absorbed nitrogen.
The Audible Alarm sounds, and the message DECO >> STOP >> xxFT (or xxM) scrolls at the top of
the screen (each on 2 seconds). The UP Arrow icon will be displayed flashing (Fig. 68), if 10 FT (3

Stop Depth.
