2 Planning a Nitrox-dive
The Smart is able to calculate …
• the maximum depth (MOD, Max. Operation Depth) to be reached with a
given mixture or
• the necessary mixture (Best Mix) for a dive with a given depth or
• for a given mixture the maximum dive time or
• the CNS O
2
%-value at a certain depth.
2.1 Calculating the Max. Operating Depth (MOD)
1. Set the desired percentage of oxygen (see page 14).
2. Activate the dive planner as described on page 27.
3. Observe the depth indications and note the greatest depth displayed. This is
your maximum depth for a dive with the set mixture and the set maximum
partial pressure of oxygen.
2.2 Calculating of the mixture for a given depth (Best Mix)
1. Activate the dive planner and observe the maximum depth displayed.
2. If the desired depth is not reached or exceeded, leave the dive planner (B-E),
alter the percentage of oxygen and return to the scrolling no-stop times.
Repeat this procedure until the desired depth appears as the maximum
depth.
3. The displayed percentage of oxygen is now the ideal one for this depth.
After entering the desired percentage of oxygen (see page 14) and activating the dive planner as described
on page 27 you can…

3 Leaving the Dive Planner
With the contacts B and E you can leave the Dive Planner. This also occurs after
three minutes without operation.
