POSEIDON SE7EN - Dive Log Data; Bluetooth Connection

Poseidon SE7EN User Manual Chapter 1
Page 8
IMPORTANT:
If a user removes the battery from the rig they were diving and
then uses that battery in a different Poseidon SE7EN unit for
subsequent dives, the decompression data in the rebreather
system will differ from those contained in the battery. To ensure
that a safe decompression situation will always exist, the
backpack computer will take the most conservative tissue-
tension data for each of the nine separate compartments of
the decompression engine from the two sets of values, and use
those to construct a new, worst-case tissue model to be used
on all subsequent dives. This will result in a decompression
penalty (and therefore reduced repetitive no-decompression dive
times) for the user who may have had a lower decompression
exposure before swapping batteries. Conversely, a user with a
known higher decompression debt transferring their battery to
a Poseidon SE7EN with a known lower decompression debt will
see little difference in how the rig tracks decompression (except
see Warning message below).
DANGER:
If a user swaps batteries with another Poseidon SE7EN unit than
the one they were diving, and if they incurred a decompression
debt, and if the battery computer memory storing the
decompression information is corrupted (e.g. from inadvertant
electrostatic discharge) there is a possibility that the computer
system may only recognize the rebreather system’s stored
decompression data. In that event, and if the previous diver of
that rebreather did not incur as serious a decompression debt,
then swapping batteries could lead to serious injury or death
from incorrect decompression on subsequent dives.
WARNING:
If a user changes batteries with a Poseidon SE7EN unit other
than the one they were most recently diving and then turns
on the power of the new Poseidon SE7EN with their original
battery installed, the Pre-Dive test routine will FAIL Test 40
(decompression comparison between battery and backpack
computers). This is a warning that there is a difference in the
decompression data stored in the rebreather’s computer and
the battery just inserted. The system will now prompt you for
conrmation while simultaneously scrolling dECO rESEt through
the PO2 eld. The user assumes all responsibility for their own
decompression safety in this event. The rebreather will calculate
decompression based on the most conservative values from
each set of decompression data.
Dive log data
The Poseidon SE7EN automatically creates an extensive dive log every time the system is
powered-up. The information stored in this log will be of signicant interest in reconstructing
dives and learning about how the rig and you behave during a dive. A Windows or Mac OSx
based SE7EN dive log reviewer/congurator are available as a download from Poseidon (www.
poseidon.com). In general, the unit will store approximately 20 hours of dive time; more if the
dives were of a simple nature with uncomplicated proles. Examples of the common types of
data you can review are battery information, dive time and depth. However, the dive log contains
much, much more information.
Bluetooth connection
Make sure that your computer is equipped with a standard Bluetooth device. If not install one.
Make sure that your Poseidon SE7EN unit is turned on by inserting the battery physically. This
is required to set the unit in pair mode. Once inserted the pairing mode willl be enables for
2 minutes. Starting the unit through the wet switch will not enable pairing mode.
Once the unit is paired it will be possible to connect to the SE7EN when unit is active regard-
less of power up method.
