WARNING: SET THE CORRECT ALTITUDE SETTING! When diving at altitudes greater
than 300 m (980 ft), the altitude setting must be correctly selected in order for the computer
to calculate the decompression status. The dive computer is not intended for use at altitudes
greater than 3000 m (9800 ft). Failure to select the correct altitude setting or diving above
the maximum altitude limit will result in erroneous dive and planning data.
NOTE: If you are doing repetitive dives at an altitude other than the previous dive
altitude, change altitude setting to correspond to the next dive after the previous dive ended.
This ensures more accurate tissue calculations.
5.7.5. Safety stop time
Safety stop is always recommended for every dive over 10 meters (33 ft). You can adjust the
safety stop to be 3, 4 or 5 minutes (the default is 3 minutes).
See 5.8.1. Safety stops.
5.7.6. Last stop depth
You can adjust the last stop depth for decompression dives under Dive options » Algorithm »
Last deco stop. There are two options: 3 m and 6 m (9.8 ft and 19.6 ft).
By default, the last stop depth is 3 m (9.8 ft).
NOTE: This setting does not aect the ceiling depth on a decompression dive. The last
ceiling depth is always 3 m (9.8 ft).
TIP: Consider setting the last stop depth to 6 m (19.6 ft) when you dive in rough sea
conditions and stopping at 3 m (9.8 ft) is challenging.

5.8.1. Safety stops
A three (3) minute Safety stop is always recommended for every dive over 10 meters (33 ft).
When a safety stop is required, the minimum ceiling value (3 m) appears in the switch window.
The time for a safety stop is calculated when you are between 2.4 and 6 m (7.9 and 20 ft).
This is presented with up and down arrows on the left side of the stop depth value. Safety
stop time is shown in minutes and seconds. The time may exceed three (3) minutes if you
ascend too fast during the dive. Ascent speed violation increases the safety stop time with
minimum 30 seconds. If violations happened several times, the additional stop time is longer.
Safety stops can be set to three (3), four (4), or
five (5) minutes in the Algorithm menu under
Dive options.
There are two types of safety stops: voluntary and mandatory. Safety stop is mandatory if
exceeding the suggested maximum ascent speed during the dive. If the stop is mandatory,
