DISPLAY BELOW CEILING ZONE

The CEILING/ASC TIME symbol and upwards pointing arrow indicate that you are

below the ceiling zone (Fig. 3.14). You should start your ascent immediately.

DISPLAY AT CEILING ZONE

When you reach the ceiling zone, the display will show you two arrows pointing toward

each other (the “hour glass” icon, Fig. 3.15). The two arrows pointing toward each other

will be shown between the minimum ceiling and 1.8 m [6 ft] below the minimum ceiling.

All decompression stops must be performed at or below the ceiling depth range.

The depth of the ceiling will depend on your dive profile. It will be fairly shallow when

you enter the decompression mode, but if you remain at depth, it will move downward

and the ascent time will increase.

The ceiling depth will be shown on the left side of the center window.

When the sea surface is rough, it may be difficult to maintain a constant depth near the

surface. In this case it will be more manageable to maintain an additional distance below

to the ceiling, to make sure that the waves do not lift you above the ceiling. SUUNTO

recommends that decompression takes place deeper than 4 m [13 ft], even if the indi-

cated ceiling is shallower.

NOTE: It will take more time and more air to decompress below the ceiling than at the

ceiling.

DIVE, AT THE CEILING ZONE

The two arrows (a) point at each other ("hour

glass"). You are at the ceiling zone at 3.5 m

[11 ft] (c) and the ceiling is at 3 m [10 ft] (b).

Note the downward pointing arrow and the

blinking Er warning. You should immediately

(within 3 minutes) descend to or below the

ceiling.
