General info
This user manual describes the settings and differences of the Galileo technical software
version (herein referred to as “Tec SW”) compared to the main Galileo user manual.

Galileo Tec SW has been developed for experienced divers, whereas the standard original
software included on your Galileo at the time of purchase has all the features that are needed
for safe recreational diving.

You should be trained and properly certied by a recognized agency in technical diving
before using Tec SW. Decompression diving, diving with high oxygen percentage blends,
multi gas diving and mixed gas diving all require skills and demand know-how that only
specic training and education can provide. A dive computer is an electronic instrument that
cannot make decisions for you and can not take all parameters into account while diving.
In technical diving a dive computer is not the primary instrument to follow during the dive.
Before the dive you must make a plan and during the dive follow it. If your plan and the
computer show different schedules, follow the more conservative one.

If you decide to revert to using Galileo standard software after installing Tec SW, you may return to
SW version 1.7 or higher. Downloading an earlier (lower number) versions will use the Galieo memory
differently and your dive computer will not operate correctly and may lock up.

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, Trimix, mixed gases, 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 Tec SW.
Warnings
Both this Trimix model and trimix diving are developed for healthy, physically t, advanced
divers. You should have regular medical check-ups with a specialized physician, conrming
your physical aptitude for diving. This is even more important for technical diving.
Patience is a very important characteristic to maintain when conducting complex dives. It is
necessary to build your personal depth limit and decompression amount based on your real
diving experience and then increase little by little as you gain experience.
Tec SW is not designed for commercial diving. Special procedures such as surface supplied
gas, heated suit, decompressing in a chamber or bell and long, high workload dives may cause
algorithm to calculate incorrectly or even disturb the operation of the Galileo dive computer.
Never dive without a backup instrument. It is imperative to always have backup instruments
for depth, time and tank pressure, as well as a dive table with you while diving.
Plan your dives in advance and cross check your plan with another commercial planner program or
table. Your dive plan should always include reserve gas amounts sufcient to handle emergencies
and/or delays. Always make bail out tables for the dive.
Technical diving is not for everyone. Decompression diving, especially with Helium mixes, will
always have a higher inherent potential for an accident which could lead to permanent injury
and death. The risk may be higher due to differences in an individual’s physical condition,
environmental conditions, human errors, etc. If you are not willing to take the risk, don’t dive!
