The next most important region is the upper-left part of the screen, where the current PO
2
value is displayed (2 in gure 3-2). The lower half of the screen includes basic information
about depth (on the left side, 3), and time (on the right side, 4). The left and right edges of the
screen (5) include bar graphs that represent the current capacity of the diluent (left side) and
oxygen (right side) cylinders, as a percentage of total cylinder capacity. Finally, the top edge of
the screen (6) includes a bar graph that represents the current ascent rate of the diver.
When the Poseidon MKVI electronics are started (via the wet switch, or when the battery is
inserted into the unit), the LCD screen momentarily shows all elements of the display, as illus-
trated below. Each of these elements is described in detail below.

DANGER:
If the Primary Display screen is ever blank while diving the
Poseidon MKVI, immediately commence an abort to the surface
in Open-Circuit mode (regardless of whether the HUD Vibrator is
activated). Failure to do so could lead to serious injury or death.
