Use of this manual

The Divesoft Freedom is intended for use exclusively by a trained person who is capable of fully understanding the instructions contained in this manual.

This manual provides operating instructions for the hardware and software (firmware) version of the Divesoft Freedom written on the tittle page.

Safety

Warning: This computer calculates a decompression profile using a mathematical model. It does not know your specific physiological decompression requirements. There is always a risk of decompression sickness (DCS) for any dive profile even if you follow the dive plan prescribed by dive computer. No procedure, dive computer or dive table will prevent the possibility of DCS or oxygen toxicity!
Warning: Use backup instruments! Ensure that you have access to backup instruments to measure depth and time. Ensure that you have access to a backup method of decompression profile calculation. Never risk your life on only one source of information.
Warning: Always check the device before diving in order to ensure that the display works, the device has not run out of battery power and all settings are correct.
Warning: All software contains bugs and the firmware of the Divesoft Freedom is no exception. The computer can probably do unintended things.
Warning: This computer may malfunction at any time. The question is not whether it will fail but when it will fail. Always have a plan on how to handle failures.

Responsibility of the Divesoft Freedom user

A Divesoft Freedom user must accept the fact that diving involves risk. Adherence to everything that the user has learned in the Divesoft Freedom’s technical documentation and in training can reduce the risk but cannot eliminate it. Safety when diving is further enhanced by regular training, methodical education and adherence to good diving practices. Technical diving requires a far higher degree of care and discipline than recreational diving.
If you do not accept the risk and you are not a trained, careful and disciplined diver, do not dive with the Divesoft Freedom.
