DEEP STOP (DS), No Deco only

When the DS selection is set On, it will trigger during NORM No Deco dives when you 

descend to 80 FT (24 M), then calculate (and continually update) a Stop Depth equal to 

1/2 the Max Depth. 

While 10 FT (3 M) deeper than the calculated DS, you will be able to access a DS Pre-

view screen that will display the current DS Stop Depth/Time.

Upon initial ascent to within 10 FT (3 M) below the calculated Stop Depth, a DS screen 

displaying a Stop Depth at 1/2 the Max Depth will appear with a Countdown Timer 

beginning at 2:00 (min:sec) and counting down to 0:00.

>  If you descend 10 FT (3 M) below, or ascend 10 FT (3 M) above, the calculated Stop 

Depth for 10 seconds during the countdown, the No Deco Main will replace the 

DS Main display and the DS feature will be disabled for the remainder of that dive.  

There is no Penalty if the DS is ignored.

>  In the event that you enter Deco, exceed 190 FT (57 M), or a High O2 condition (=> 

80%) occurs, the DS will be disabled for the remainder of that dive.

>  The DS is disabled during a High PO2 Alarm condition (=> Set Point).

SAFETY STOP (SS), No Deco only

If set On:

Upon ascent to within 5 FT (1.5 M) deeper than the SS Depth set for 1 second on a No 

Deco dive in which Depth exceeded 30 FT (9 M) for 1 second, a beep will sound and a 

SS at the Depth set will appear on the Main display with a countdown beginning at the SS 

Time set and counting down to 0:00 (min:sec).
