DISPLAY BELOW THE FLOOR
The blinking ASC TIME and an upward pointing
arrow indicate that you are below the fl oor (Fig. 3.17.).
You should start your ascent immediately. The ceiling
depth is shown on the left and the minimum total ascent
time on the right side of the center window.
DISPLAY ABOVE THE FLOOR
When you ascend above the fl oor, the ASC TIME
display stops blinking and the upward pointing
arrow disappears. (Fig. 3.18.) Decompression will
now begin, but is very slow. You should therefore
continue your ascent.
DISPLAY AT THE CEILING ZONE
When you reach the ceiling zone, the display will show
you two arrows pointing at each other (the "hour glass"
icon, Fig. 3.19.). Do not ascend above this zone.
During the decompression stop, ASC TIME will count
down towards zero. When the ceiling moves upwards,
you can ascend to the new ceiling. You may surface
Fig. 3.19. Decompression
dive, at ceiling zone. Two
arrows point at each other
("hour glass"). You are in the
optimum ceiling zone at 3.5
m [11 ft] and your minimum
ascent time is 5 minutes.
