The general parameters for EAN dives are the
same as those for compressed air dives (AIR), with
the addition of settings for the percentage of
oxygen and its maximum partial pressure.
We recommend that you carefully read the “Set
Mode - AIR” section before proceeding further.

WARNING
The use of oxygen rich mixes exposes
the diver to different hazards from those
associated with compressed air. The
diver should be aware of these risks and
understand how to avoid them.

WARNING
Do not use breathing mixes with an
oxygen percentage greater than 50%.

WARNING
It is essential to correctly set the oxygen
percentage in the mix to ensure correct
readouts of:
• No decompression time remaining
• Decompression stop times
• Alarm on exceeding the maximum
permitted PPO

PUCK sounds an alarm when the partial pressure
of oxygen reaches a pre-established limit. This
limit can be varied from a minimum 1.2 bar to a
maximum of 1.6 bar, in increments of 0.1 bar.
As this value changes, PUCK will show the
maximum dive depth compatible with the oxygen
percentage and maximum partial pressure that
have been programmed.
To set the desired value, press and hold the button
when the display reads PPO
