OVERVIEW OF NAV (NAVIGATION) MODE
As indicated previously, the d.i.P is configured with a unique
NAV (Navigation) Mode. Information such as SNs (Serial
Numbers) or NAV Leg #s, SN Headings, and SN CDTs (Count
Down Times) are entered only using the PC Interface program.
Once a Dive is started in NAV Mode, it essentially stays in Dive
Mode and data displayed continues without regard to Depth
(e.g., there is no real Surface Mode, only Dive Mode while on
the surface with zero Depth).
If the diver surfaces after an initial Descent is made, Depth will
be displayed as 0,0 M (0 FT) instead of as 3 dashes as it is upon
surfacing after a NORM Dive.
When NAV Mode is set ON, the d.i.P will initially enter NAV
Dive Mode upon Descending to 0,6 M (2 FT) for 3 seconds and
display the NAV DIVE MAIN screen.
Sample screens:
• Fig 55 - Depth prior to the first Descent as 3 dashes (- - -) M
(FT).
• Fig 56 - Depths after Descent to 0,6 M (2 FT) as actual.
• Fig 57 - Depths of 0,3 and 0,0 M (1 and 0 FT) as 0,0 M (0
FT).
