Decompression Status Verication. In this test, the two sets of
decompression data (one stored in the rig electronics, and
one in the battery), are validated and compared (see relevant
discussion in Chapters 1 & 2). In addition to comparing and
validating the two sets of tissue-tension data, this test also
compares the serial numbers of the battery and the main elec-
tronics, as well as the time-stamp on both.
Sufcient Oxygen Supply Pressure. This test requires that the
oxygen cylinder contains sufcient pressure for a dive to be
started (at least 25% of maximum capacity).
Mouthpiece Open-Circuit Position. This test requires that the
mouthpiece be in the Open-Circuit (OC) position in order to
pass. During this test, if the system does not detect the OC
position, the red LED and the vibrator on the Head-Up DIsplay
(HUD) will pulse continuously to signal the diver to adjust the
mouthpiece position.

The most common cause of failure of this test is inserting a battery from one
user into the rig of another user. In such cases, the decompression data will
not match. The rst automatic pre-dive routine to encounter this condition
will fail, alerting the diver to the mis-matched data. Either replace the battery
with the correct one or conrm the battery switch by using the wet switch
dry/wet sequence and the pre dive tests will continue. The system will
assume the worst-case set of decompression data among the two dispa-
rate sets.
1) Ensure the oxygen cylinder is connected to the oxygen regulator, and that
the valve is turned on; 2) Ensure that the oxygen cylinder contains sufcient
pressure; 3) If test failure persists, contact an authorized Poseidon Service
Center for repair.
1) Standard Response; 2) If test failure persists, contact an authorized
Poseidon Service Center for repair.
1) Ensure that the moutpiece is fully in the OC position (sometimes requires
rm pressing on the mouthpiece lever); 2) Ensure that the HUD is properly
positioned on the top of the mouthpiece, and that the exhaust cover is
holding it tightly in place; 3) If test failure persists, contact an authorized
Poseidon Service Center for repair.
39 Intro Test.
Mouthpiece Closed-Circuit Position. This test requires that the
mouthpiece be in the Closed-Circuit (CC) position in order to
pass. During this test, if the system does not detect the CC
position, the red LED and the vibrator on the Head-Up DIsplay
(HUD) will pulse continuously to signal the diver to adjust the
mouthpiece position.
120 0=Timeout 1) Ensure that the moutpiece is fully in the CC position (sometimes requires
rm pressing on the mouthpiece lever); 2) Ensure that the HUD is properly
positioned on the top of the mouthpiece, and that the exhaust cover is
holding it tightly in place; 3) If test failure persists, contact an authorized
Poseidon Service Center for repair.
41 This test requires the user to conrm that:
1. They have a canister installed
2. It contains sufcient unused absorbent to complete the
dive.
120 0=Timeout 1)Ensure to conrm canister good via wet switch wet procedure. 2) If test
failure persists, contact an authorized Poseidon Service Center for repair.
