General alert
Figure 3-9. General alert.
The General alert symbol located in the Alarm
Signal Area will ash in synchrony with any
other parameter(s) on the screen that is/are
inappropriate or out of acceptable range. This
signal is intended to catch the diver’s atten-
tion, and prompt the diver to scan the other
elements on the screen to see which value(s)
is/are also ashing. As long as one of the other
displayed values on the Primary Display is
ashing, the General Alert symbol will also
ash.
Electronics alert
Figure 3-10. Electronics alert.
The Electronics alert symbol indicates that a
problem has been detected with the electron-
ics, such as a cable failure or electronics
failure in one of the CAN units.
The specic cause is recorded in the logged
data. If the Electronics alert symbol is shown,
ABORT the dive or DO NOT DIVE.
Decompression ceiling alert
Figure 3 -11. Decompression ceiling alert.
The Decompression ceiling alert symbol will
ash when the diver has incurred a decom-
pression obligation. The current decompres-
sion stop is displayed in a text message.
With the 40m recreational battery installed the
Poseidon SE7EN+ is not intended for decom-
pression diving, so the dive should be termi-
nated whenever this icon is displayed. The
diver should ascend towards the surface at a
slow and controlled rate, watching the Primary
Display for the Stop Alert and additional
decompression information (see below).
Stop alert
Figure 3-12b. Stop alert.
The Stop alert symbol located in the Alarm
Signal Area is displayed in one of two circum-
stances: either the diver is ascending too
rapidly, or the diver has reached the decom-
pression stop depth (“ceiling”). In either case,
the appropriate response is to immediately
stop ascending, and the diver should maintain
the current depth until the symbol
disappears.
IMPORTANT:
It is the sole responsibility of each and every Poseidon SE7EN+
diver to understand all of the alarm systems and conditions,
monitor them throughout every dive, and respond appropriately
to any alert status.
In the unlikely event that a diver incurs a
decompression obligation (i.e., the
Decompression Ceiling Alert is displayed),
and the diver then ascends above the depth
at which the Decompression Stop Alert is
displayed, the Descend arrow will ash. In
this situation, simply descend gradually until
the Descend arrow no longer ashes, and
remain at that depth until the Decompression
Stop Alert no longer displays.
