Set the correct altitude! The FREEDOM computer does not contain an atmospheric pressure sensor
which that would detect altitude. Altitude is an essential parameter for computing the
decompression procedure. Wrong setting may result in DCS!
A dive computer is a personal device. Sharing one computer between several divers affects the
decompression procedure.
Do not reset decompression data if it is used by one diver repeatedly. Resetting the decompression
data serves for use by diving schools and diving rental services. Reset of the decompression data can
be used only if the original diver will no longer use this computer.
Use conservative gradient factor setting. The DIVESOFT FREEDOM computer uses Baker’s gradient
factors for setting decompression conservatism. Be sensible and use a conservative setting adjusted
to your physical and ambient conditions. Decompression is influenced especially by: physical fitness,
health, body constitution, mental condition, exertion, stress, hydration, CO

level, temperature,
individual predisposition, gender and age.
A higher ascent rate is very hazardous and may cause DCS. Do not exceed the maximum ascent rate.
If you do not follow decompression information, your real ascent time could be longer than the
device displays. This could be due to spending more time at depth, a slower ascent than the set
ascent rate and decompression stops at depths lower than those recommended. These factors will
also increase the amount of air required to reach the surface.
Do not exceed decompression stops and never ascend above the ceiling.
The ceiling is a serious
limit. Going beyond this limit enormously increases the risk of DCS.
Always analyze the breathing gases that you will take with you! Use Divesoft He/O2 Analyzer for
save recognition.
Ensure the water resistance of the device!
Do not exceed maximum altitude! Atmospheric pressure decreases with as altitude increases. It is
the same principle as pressure reduction as a diver ascends. Maximum altitude information shows
the diver the maximum altitude which would be reached without DCS risks at the given moment.
Check your oxygen clock often! If your CNS oxygen exposition exceeds the 75% value, start your
ascent immediately. When cave diving, stricter rules are applied.
Never exceed the maximum operational depth (MOD) for your gases! Exceeding MOD could cause
death.
When diving with hypoxic gas mixtures, never breathe this mixture when the partial pressure is
lower than 0.18 bar!
Always use realistic SAC rates and conservative turn pressures during dive planning.
Always take heed of visual and vibrating alarms of the device!
You need to take into account the danger of nitrogen narcosis. The FREEDOM does not issue any
warnings in connection with this danger.
