SAFETY CONSIDERATIONS
You must carefully read and understand this entire manual before using your Subgear XP-3G.
WARNING
Diving has many inherent risks. Even if you follow the instructions of this manual in a careful manner, it is
still possible that you may be seriously injured or die from decompression sickness, oxygen toxicity or some
other inherent risk of scuba with Nitrox or compressed air. Unless you are fully aware of these risks and are
willing to personally accept and assume responsibility for those risks, do not use Subgear XP-3G.
Guidelines for the use of Subgear XP-3G
The following guidelines for using Subgear XP-3G are derived from the latest medical research and
the recommendations of the American Academy of Underwater Sciences for diving with diving
computers. Following these guidelines will greatly increase your safety while diving, but cannot
guarantee that decompression sickness or oxygen toxicity will not occur.
