ALGORITHM

The algorithm is based upon Haldane's theory using maximum allowable nitrogen levels developed by Merrill Spencer. Repetitive diving control is
based upon experiments designed and conducted by Dr. Ray Rogers and Dr. Michael Powell in 1987. Diving Science and Technology® (DSAT), a
corporate affiliate of PADI®, commissioned these experiments. To create even greater margins of safety with respect to decompression, a Conserva-
tive Factor as well as No Decompression Deep and Safety Stops can be included for No Decompression dives.
CONSERVATIVE FACTOR
When the CF is set On, the dive time remaining, No Decompression/O2 MIN, which are based on the algorithm and used for N2/O2 calculations
and displays relating to Plan Mode, will be reduced to the values available at the altitude level that is 3,000 (915 m) higher than the actual altitude
at activation. Refer to the charts in the back of this manual for dive times.
DS (DEEP STOP)
When the DS selection is set ON, it will trigger after descending deeper than 80 ft (24 m). The Sage then calculates (continually updating) a Stop
Depth equal to ½ the Max Depth.
NOTE: The Deep Stop feature only works in DIVE mode while within No Decompression times.
• While 10 ft (3m) deeper than the calculated Deep Stop, you will be able to access a Deep Stop Preview screen that will display the current calcu-
lated Deep Stop Depth/Time.
• Upon initial ascent to within 10 ft (3 m) below the calculated Stop Depth, a Deep Stop screen displaying a Stop Depth at ½ 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 Decompression Main will replace the Deep Stop Main display
and the Deep Stop feature will be disabled for the remainder of that dive. There is no penalty if the Deep Stop is ignored.
• In the event that you enter Decompression, exceed 190 ft (57 m), or a High O2 SAT (Oxygen Saturation) condition, ≥ 80%, occurs, the Deep
Stop will be disabled for the remainder of that dive.
• The Deep Stop is disabled during a High PO2 Alarm condition, ≥ set point.
SS (SAFETY STOP)
Upon ascent to the Safety Stop depth 20 ft (6 m) 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 20 ft (6 m) will appear on the NX/AIR Dive Main display with a countdown beginning at the Safety
Stop time 3:00 (min:sec) and counting down to 0:00.
• 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 20 ft (6 m), the Safety Stop depth,
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 the Safety Stop depth, 20 ft (6 m), 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.

LOW BATTERY WHILE ON THE SURFACE

WARNING: Change the battery before diving if your Sage indicates the Battery Low Warning or Alarm.
Warning Level
• The Sage functions continue but but screen brightness is limited to 60% max.
• The Battery icon and LOW BATTERY message appears amber.
