SAFETY CONSIDERATIONS You must carefully read and understand this entire manual before using your Galileo. 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 diving with Nitrox or compressed air.

• Only make dives that are appropriate to your level of dive training. Galileo does not increase your knowledge of diving. • Always dive with back-up instruments. Make sure that you always use back-up instrumentation including a depth gauge, submersible pressure gauge, digital bottom timer or dive watch, and have access to decompression tables whenever diving with a dive computer.
Welcome to UWATEC dive computers and thank you for purchasing Galileo. You are now the owner of an extraordinary partner for your dives. This manual provides you easy access to UWATEC state of the art technology and Galileo’s key features and functions.

2. Menus, settings and functions 2.3.5 Nitrox reset time (default: no reset) If you set the computer to an oxygen concentration higher than 21% (diving with Nitrox), you can decide whether the computer should revert back to 21% (air) at some point in time or if it should stay set to the given oxygen concentration until you change it manually.
2. Menus, settings and functions 2.3.7 Desaturation reset Galileo allows you to reset the desaturation in the computer. Any tissue saturation information from a recent dive will be reset to zero and the computer treats the next dive as a non-repetitive dive. This is useful when the computer is loaned to another diver who has not dived in the last 48 hours.

4. Galileo and SmartTRAK (PC interface) Downloading dives and organizing your logbook Galileo’s memory allows you to store approximately 100 hours of dive profile information in 4 second sampling intervals. With SmartTRAK you can transfer this information to the PC in order to visualize and analyze your dives on the monitor.
4. Galileo and SmartTRAK (PC interface) You can choose between transferring all dives or new dives only (default setting) from Galileo’s memory. If you choose to transfer new dives only, SmartTRAK will only transfer dives that are more recent than the most recent dive already saved in the PC logbook. Once the data is downloaded, a window will show you a summary table of all dives;...

5. Taking care of Galileo ! WARNING 8. Wait for 30 seconds, then insert the new battery. Ensure that the “+” side - Never touch the metal surface of the is facing away from the transmitter. The battery with bare fingers. The two battery transmitter can be damaged if you do poles must never be short-circuited.
5. Taking care of Galileo Your dive instrument is manufactured with high-quality components that can be recycled and reused. Nevertheless these components, if not properly managed in accordance with the regulations on waste electrical and electronic equipment, are likely to cause harm to the environment and/or to human health. Customers living in the European Union can contribute to protecting the environment and health by returning old products to an appropriate collection point in their neighbourhood in accordance with EU Directive 2012/19/UE.
