40 Decompression Status Verication. 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.

data
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 conrm 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) Standard Response; 2) 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 conrm that:
1. They have a canister installed
2. It contains sufcient unused absorbent to complete the
dive.
120 0=Timeout 1)Ensure to conrm canister good via wet switch wet procedure. 2) If test
failure persists, contact an authorized Poseidon Service Center for repair.
38 Depth/Temperature Sensor Validation. This test ensures that
the temperature sensor embedded in the depth sensor is
working correctly.

1) Standard Response; 2) If test continues to fail, ensure loop temperature
is within limits; 3) If test failure persists, contact an authorized Poseidon
Service Center for repair.
35 Secondary Oxygen Sensor Validation. This test measures the
voltage output from the secondary oxygen sensor, to ensure it
exceeds a minimum threshold value. Although it is possible
that the gas mixture in the breathing loop is hypoxic, a failure
of this test more likely indicates a failed oxygen sensor and / or
a broken wire. This test does not ensure proper function of the
sensor (veried during the calibration routine, t53).

1) Inspect the secondary oxygen sensor, the wires leading from it, and the
electrical contacts at the back of the sensor cavity, and replace the sensor
and/or wires if either are suspect; 2) Standard Response; 3) If test failure
persists, contact an authorized Poseidon Service Center for repair.
