YOU ARE ADVISED TO MAKE A

DEEPSTOP AT 18 M. THE SECOND

INDICATOR SHOWS THAT YOU HAVE 110

SECONDS LEFT OF YOUR DEEPSTOP.

In order to optimize the response to different increased risk situations, an additional category

of stop, referred to as a Mandatory Safety Stop, has been introduced. The combination

of stop types depends on the user settings and the specific dive situation.

To get the most from the RGBM safety benefits, refer to Section 10.2. RGBM.

5.3. Emergency ascents

Before you dive, you must have the dive plan created with the Suunto Dive Planner printed

out on a slate. You must also have a back-up plan for lost gases. In the unlikely event that

the dive computer malfunctions during a dive, start using an alternative depth gauge and

timer and following the ascent schedule and gas switches that are on the slate. If you dive

using only air, follow these steps:

Assess the situation calmly and then move promptly to less than 18 m/60 ft.

At 18 m/60 ft, slow down your ascent rate to 10 m/33 ft per minute and move to a

depth between 3 and 6 m/10 and 20 ft.

Stay there for as long as your gas supply will safely allow. After reaching the surface,

do not dive for at least 24 hours.

In the event that the dive computer functions but a required gas is not available, you can

use your diving partner's gas, which is set as a secondary gas on the dive computer.

Displayed ASC TIME is not correct, but the decompressions are calculated correctly.

In the event that a required gas is not available at all, decompress for as long as you can

by using the next most suitable gas that has the highest oxygen content. Notice that the

oxygen content should be low enough to not violate the maximum partial pressure of

oxygen (PO

5.4. Dive computer limitations

While the dive computer's calculations are based on current decompression research and

technology, it is important to realize that the computer cannot monitor the actual

physiological functions of an individual diver. All decompression schedules currently known

to the authors, including the U.S. Navy Tables, are based on theoretical mathematical

models, which are intended to serve as a guide to reduce the probability of decompression

illness.

5.5. Mixed gas diving

Diving with gas mixes provides you with an opportunity to increase bottom times, shorten

decompression times, decrease the oxygen partial pressure at depth, and reduce the risk

of nitrogen narcosis or decompression illness by reducing the nitrogen content in the gas

mix.

However, when the gas mix is altered or depth increased, the oxygen partial pressure is

generally increased. This increase exposes the diver to an oxygen toxicity risk not usually

considered in recreational diving. In order to manage this risk, the dive computer tracks

the time and intensity of the oxygen exposure and provides the diver with information to

adjust the dive plan in order to maintain oxygen exposure within reasonably safe limits.

In addition to the physiological effects of enriched air on the body, there are operational

considerations to be addressed when handling altered breathing mixes. Elevated concen-

trations of oxygen present a fire or explosion hazard. Consult the manufacturer of your

equipment to check its compatibility with nitrox.
