basic dive information, as well as audible and visual warnings.
In simulation mode the time has been speeded up, moving four times faster than
real time when diving and 12 times as fast on the surface.
Enter the Dive Simulation Mode
To enter the dive simulation mode, keep your moistened fingers against the
TIME/MODE and COM contacts. A bar on the right-hand side of the display will
scroll through the different modes available. Lift your fingers when the scroll bar is in
line with the letters dSI (dive simulation) next to the screen and the text dSi is shown
on the display. If you accidentally enter the wrong menu selection, simply touch all
the three contacts simultaneously to return to the READY display.
Before Diving (simulation)
To make the first dive. When you enter the dive simulation mode, as described
above, the initial display is the READY display. Next, enter the DIVE PLANNING
mode by touching the ON/PLAN and COM contacts for about one second. Release
your fingers immediately when you hear a short beep. The DIVE PLANNING display
will rapidly cycle through the no-decompression limits for various depths.
Diving (simulation)
To simulate a dive, use the three contacts as follows:
To descend: touch the ON/PLAN and COM contacts for as long as you
want to descend.
To ascend: touch the TIME/MODE and COM contacts. You will have to lift your
fingers momentarily to avoid an excessive ascent speed rate.
We are now ready to descend. Keep your fingers on the ON/PLAN and COM
contacts for a couple of seconds at a time. Descend step by step to about 30 m
[100 ft]. After about 9 minutes of diving, start the ascent. Check your ascent rate on
the ascent rate indicator. The ascent rate is indicated in the upper left corner by
one, two, or three bars indicating a maximum ascent rate of 5, 7.5, and 10 m/min
[16, 25, and 33 ft/min, respectively]. If you exceed the maximum allowed ascent rate
of 10 m/min [33 ft/min], all three bars and a blinking SLOW will be shown.
Remember to make a safety stop at a depth of about 4.5 m [15 ft] before surfacing.
Now it is time to surface.
Surface Interval (simulation)
Back on the surface the display shows the maximum depth and dive time of your
simulated dive and the elapsed surface interval time or the no-flying time display.
