2.1. - UFDS display and controls.
Archimedes II computer is equipped with a “
User Friendly
Display System
” (UFDS) display, which “escorts” the diver
during its operation. Various icons on the display will indicate
the operation that may be carried out at that moment. As an
example, the “light” icon ( ) (at the bottom on the right) indi-
cates that by depressing button C the back-illumination will
be engaged. This establishes a direct “dialogue” and a clear
understanding of every function.
Archimedes II’s different programs are visible by repeatedly
depressing button B (Mode). This is the key to operating the
system. They are clearly indicated by the alpha-numeric
UFDS display. Some programs have sub-menus, which are
switched on by depressing buttons A and C. This will allow as
well as change the setting on the surface. Depressing button
C ( ) engages the display back-illumination.
2.2. - On surface, before diving.
As previously noted, the Archimedes II is always on. When
diving at altitude, it is important to check that the appropriate
altitude adjustments have occurred. This function is carried
out automatically, updating every 10 minutes. Altitude adjust-
ment values will be displayed as follows:
no icon ( )- from 0 – 2.625 ft. (picture 1)
- from 2.625 – 5.250 ft. (picture 1-a)
- from 5.250 – 7.874 ft.
- from 7.874 – 19.685 ft.
- more than 19,685 ft. -out of range
Each icon indicates that the computer has automatically
modified its own mathematical model to adjust to proper
altitude.
DANGER: Diving at altitudes greater than 9,842 ft.
above sea level involves an increased risk of decompres-
sion sickness.
Diving at higher altitudes than normal may cause alterations
of the nitrogen balance between the human body and the
environment.
