A&D 2 Plus owner manual Guidelines for Using the Monitor 3 Air

Page 4

The Monitor 3 Air is a technically advanced tool based on a biophysical model of decompression theory. However, neither it nor any other diving computer (or table) can actually monitor the physical changes that occur in your body as you dive. Each diver varies in his or her susceptibil- ity to decompression sickness, and that susceptibility may vary from day to day. Decompression modeling is an inexact science; it is based, at least partly, on certain unproven assumptions. Therefore, you must dive responsibly and to carefully follow all standard safe diving practices as well as the warnings and cautions contained in this manual.

Guidelines for Using the Monitor 3 Air

The following guidelines for using the Monitor 3 Air are derived from the latest medical research and the recom- mendations of the American Academy of Underwater Sciences for diving with dive computers. Following these guidelines will increase your safety while diving, but cannot guarantee that decompression sickness will not occur.

1.In accordance with the recommended maximum diving limit of all instructional agencies, do not dive deeper than 130 feet (40 meters).

2.Do not use the Monitor 3 Air for planned decompres- sion diving. The decompression algorithm contained in the Monitor 3 Air should be used only for emergency or unintended decompression.

3.On all no-decompression dives with the Monitor 3 Air, make a safety stop for three to five minutes between 10 and 30 feet (3 and 12 m) before surfacing.

4.Never use the Monitor 3 Air for repetitive, “rectangular” dives deeper than 60 feet (18 meters). A rectangular dive is a dive that is performed for its duration at a uniform depth.

5.Always make the deepest dive of the day first when repetitive dives are planned, and for each successive dive make sure that the deepest portion of that dive is done at the beginning of the dive.
