INSTRUCTIONS (v. 2.7)
menu and press the
CONFIRM
button and see the option lock into place into a submenu or some
operational information the diver may want to see.
WARNING! It is imperative that the diver NOT enter the water within two
minutes of power on to avoid the inadvertent selection of inappropriate
options.
The Diver at any time may leave the selected option by making a selected
operational change to the APECS™ or the system will time out in 5 seconds and
go back to the main diving informational screen.
WARNING! Always insure that you have a breathable P02 in the loop, and
set point that will also support your planned decompression.
CHANGE SP?:
Set point selection is accessed from this option by pushing the
MENU
button to “
CHANGE SP?
” Push the
CONFIRM
button to lock in the
option. The diver will see the first of the set points that can be locked in with the
CONFIRM
button. The first set point is
MAN. Man
stands for manual. The
manual set point is an artificial set point of 0.20 and attempts to maintain a loop
PO2 of .20 (Air) at all times. The desired use is for swimming pool training,
surface swimming while breathing on the loop to avoid hypoxia, and for pre-
diving
the Megalodon to avoid wasting oxygen through solenoid injection.
Set Points:
The diver has the following set points that may be set on the fly
during the dive, or preset prior to entering the water;
MAN, 0.5, 0.7, 1.0, 1.1, 1.2,
1.3, 1.4,
and
ASP
.
ASP
stands for Auto Set Point. Auto Set Point is designed to
be used during rapid descents.
ASP
is normally selected immediately prior to
descent; as the diver descends and PO2 rises,
ASP
ensures that the PO2 does
not fall below current PO2 at any point. Once the descent is complete the diver
should select a fixed set point. The diver can select the maximum PO2 that ASP
will maintain on the
SET MAX SET POINT
menu.
WARNING!
The diver must ensure that they have a breathable PO2 at all
times and maintain the planned PO2 to support the planned
decompression.
Other considerations are
Oxygen CNS toxicity
and
Whole body Oxygen
toxicity
, the planned PO2 must insure that all oxygen hazards are avoided by
prudent CCR diving practices. So use the oxygen set points wisely.
SYSTEM MONITOR:
The second menu option after the
CHANGE SP
selection
is the
SYSTEM MONITOR
. The
SYSTEM MONITOR
page is the diagnoses
