DANGER
The Odyssey dive computer has been designed to monitor your dive profile and to calculate decompression stop(s)
requirements based on its internal model and the parameters you provide. These calculations are, at best, an estimate
of actual physiological desaturation requirements and do not guarantee a safe ascent profile. Decompression sickness
(DCS) is intrinsically linked to the gas load dissolved in the diver's body as a result of diving and to be off-gassed by the
body during the ascent and after surfacing. In scuba diving, there is no such thing as zero risk.
THE ONLY WAY NOT TO EXPOSE YOURSELF TO A PROBABILITY OF DCS IS NOT TO DIVE.
WARNING
Although we make a continuous effort to ensure that your computer is functioning properly, it is certain that your
computer's firmware contains undetected bugs. Your computer may fail at any time without warning, before or
during a dive,due to software or hardware failure.
Never risk your life on a single source of information. Plan all dives carefully, use a second computer or tables and
be prepared to execute your backup plan at any time.
You are risking your life by scuba diving and no dive computer can eliminate this risk. The dive computer is not a
substitute for the proper training, knowledge, or skills necessary to dive.

ODYSSEY - v 1.0.20G
BATTERY REPLACEMENT
•Your Odyssey operates on a standard user-replaceable AA battery. Any AA battery with a
voltage rating between 1.2V and 4.5V is compatible.
•The battery compartment is sealed with a cap on the right side of the unit. This cap can be
unscrewed (counterclockwise) with a coin.
•The new battery must be inserted with the positive
terminal first (see diagram on the case).
•The appearance of the cap seal should be checked and greased if necessary. The cap should be screwed on until it stops.
•The minimum operating time of the unit is approximately 15 hours of diving at maximum screen intensity. This time may vary depending on
the type of battery, water temperature and the length of time the Bluetooth is used.

STARTING YOUR ODYSSEY
•Your Odyssey will automatically start when submerged. This feature may not function
correctly.
We recommend that you always start your computer manually and check the settings
carefully before diving.

right and left side of the computer.
TURNING OFF YOUR ODYSSEY
•When not in the water, your Odyssey automatically shuts off after 15 minutes of
inactivity.
•When out of the water, your Odyssey shuts off manually by pressing the 2 side buttons
simultaneously.
Start and stop with simultaneous pressing
of the left and right buttons
