DECOMPRESSION MODEL The programs within the OCS simulate the absorption of nitrogen into the body by using a mathematical model. This model is merely a way to apply a limited set of data to a large range of experiences. The OCS dive computer model is based upon the latest research and experiments in decompression theory. Still, using the OCS, just as using the U.S. Navy (or other) No Decompression Tables, is no guarantee of avoiding decompression sickness, i.e.

24 hour period. The OCS will store O2 calculations for up to 10 dives conducted during a 24 hour period. If the limit for O2 is reached (100% = 300 OTU), all 5 segments of the O2BG will be displayed on the Main dive screen in place of the TLBG (Fig. 60a).

You can select DSAT or Z+. The selection will lock in for 24 hours after the last dive. DSAT has been the standard used by Oceanic in all of its dive computers until this time. It features NDLs that are based on exposures and test data which also formed validation for the PADI RDP.

Page 32 If a Deco Stop Depth greater than 70 FT (21 M) is required, operation will enter VGM. This would be preceded by DV2. Operation would then continue in VGM during the remainder of that dive and for 24 hours after surfacing. VGM turns the OCS into a digital instrument without any decompression or oxygen related calculations or displays.

Page 35 Oceanic advises that you should not use an OCS. If you exceed certain limits, the OCS will not be able to help you get safely back to the surface. These situations exceed tested limits and can result in loss of some functions for 24 hours after the dive in which a violation occurred.

Page 52: Compass.alarms
Fig. 159 - ASCENT ALARM Fig. 160 - DEPTH ALARM WARNING: You must become thoroughly familiar with setup and operation of the OCS Digital Compass before using it as your primary device for navigation. Failure to do so could result in serious errors relating to activities involving navigation.
Page 53: Reference
CAUTION: When the procedure provided in this section is used to change the Battery, you must be sure that the case o-ring is not pinched and that the OCS is water tight before conducting diving activities. Pre dive pressure testing by an Authorized Oceanic facility is highly recommended.
Page 54: Pc.interface
A USB Driver is provided on the Oceanlog CD as part of the Interface System. The OCS is configured with a Data Port located on the side (Fig. 161a) that enables it to be connected to a PC USB port using the special Interface Cable.
Page 55: Care.and.cleaning
Instrument Lens Protector. Small scratches will naturally disappear underwater. • Soak and rinse the OCS in fresh water at the end of each day of diving, and check to ensure that the areas around the Low Pressure (Depth) Sensor (Fig. 164a), PC Interface Data Port (Fig. 164b), and Buttons are free of debris or obstructions.
Page 56: Altitude.sensing.and.adjustment
> No adjustments are made during any time that the Wet Contacts are bridged. When diving in high altitude waters from 3,001 to 14,000 feet (916 to 4,270 meters), the OCS automatically adjusts to these conditions providing corrected Depth, and reduced No Deco and O2 Times at intervals of 1,000 feet (305 meters).

Page 60 1 second WARNING: If your OCS stops working for any reason while operating as a Dive Computer, it is important that you have anticipated this possibility and are prepared for it. This is an important reason for not pushing the no decompression and oxygen exposure limits, and a critical reason to avoid entering decompression.
