SAFETY STOP
Upon ascent to within 5 ft (1.5 m) deeper than the SS depth set for 1 second on a No Decompression 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 Dive Main display with a countdown beginning at the SS time set and
counting down to 0:00.
• If the SS was set for OFF, the display will not appear.
• In the event that you descend 10 ft (3 m) deeper than the Stop Depth for 10 seconds during the countdown, or the countdown reaches 0:00, the
No Decompression Main screen will replace the SS Main screen which will reappear upon ascent to within 5 ft (1.5 m) deeper than the Safety
Stop depth set for 1 second.
• In the event that you enter Decompression during the dive, complete the Decompression obligation, then descend below 30 ft (9 m); the SS Main
will appear again upon ascent to within 5 ft (1.5 m) deeper than the SS depth set for 1 second.
• If the diver ascends to within 3 ft (0.91 m) from the surface for 10 seconds, the SS is to be canceled.
• There is no penalty if you surface prior to completing the SS or choose to ignore it.
If set for Timer On
Upon ascending to 20 FT (6 M) for 1 second on a No Deco dive in which Depth exceeded 30 FT (9 M) for 1 second, 1 beep will sound and a Run
Timer will appear (if set On) displaying 0:00 (min:sec) until started.
• If the SS was set for Off or On, the Timer display will not appear.
• If you descend deeper than 30 FT (9 M) for 10 seconds, the No Deco Main will replace the Timer screen which will reappear upon ascent to 20
FT (6 M) for 1 second.
• If you ascend above 3 FT (0.91 M) for 10 seconds, or enter Deco, or a High O2 alarm condition occurs (100%), while the SS Timer is active, the
SS Timer will be disabled for the remainder of that dive.
