[. . . ] The ascent time will increase if you: remain at depth ascend slower than 10 m/min [33 ft/min], or make your decompression stop deeper than at the ceiling. These factors will also increase the amount of air required to reach the surface. WARNING! NEVER ASCEND ABOVE THE CEILING!In order to avoid doing so by accident, you should stay slightly below the ceiling. Ceiling and Ceiling Zone When in decompression, it is important that you understand the meaning of ceiling and ceiling zone: The ceiling is the shallowest depth to which you should ascend when in decompression. At this depth, or below, you must perform one or several decompression stops. All decompression stops must be performed at or below the ceiling depth. The ceiling zone is the optimum decompression stop zone. It is the zone between the minimum ceiling and 1. 8 m [6 ft] below the minimum ceiling. 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, the ceiling 44 will move downward and the ascent time will increase. Likewise, the ceiling may change while you are decompressing. 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 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 indicated ceiling is shallower. NOTE: It will take more time and more air to decompress below the ceiling than at the ceiling. Display below the Ceiling Zone The CEILING/ASC TIME and upward pointing arrow indicate that you are below the ceiling zone (Fig. You should start your ascent immediately. The ceiling depth is shown on the left side of the center window and the minimum total ascent time on the right side of the center window. Fig. 4. 19 Decompression dive, below the ceiling zone. The upward pointing arrow tells you to ascend. The ceiling is at 3 m [10 ft]. 45 Display at the Ceiling Zone When you reach the ceiling zone, the display will show you two arrows pointing at each other (the hourglass icon, Fig 4. 20). During decompression, ASC TIME will count down toward zero. [. . . ] No dealer or representation is authorized to make any modifications to this warranty or to make any additional warranty.
