SAFETY STOP
Upon ascent to within 5 ft (1.5 m) deeper than the SS (Safety Stop) 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 Safety Stop at the depth set will appear on the Dive Main display with a countdown beginning at
the Safety Stop time set and counting down to 0:00.
• If the Safety Stop 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 Safety Stop 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 Safety
Stop Main will appear again upon ascent to within 5 ft (1.5 m) deeper than the Safety Stop depth set for 1 second.
• If you ascend to 3 ft (0.9 m) of the surface for 1 second, the Safety Stop will be canceled for the remainder of that dive.
• There is no penalty if you surface prior to completing the Safety Stop or choose to ignore it.
