VT 4.0 OPERATING MANUAL
© 2002 Design, 2011 Doc. No. 12-5213-r02 (9/6/11)
NORM Mode >> for Air and Nitrox SCUBA activity with up to 4 Gases/4 TMTs.
GAUG Mode >> for SCUBA activity with up to 4 TMTs.
FREE Mode >> for breath hold diving activity with Depth/Time indication.
If no previous dive has been taken within the past 24 hours, NORM is the default mode upon activation with others ac-
cessed as described later.
At any time while operating in Surface Modes, operation will enter the Dive Mode selected upon descent to 5 FT (1.5 M) for
5 seconds.
• When Wet Activation is set Off, Dive Mode will only be activated when the unit is first activated and operating in a
surface mode.
• When Wet Activation is set On, the selected Dive Mode will activate upon descent regardless of whether is is activated
and operating first.
TRANSITION PERIOD, upon surfacing:
Operation shifts from Dive Mode to Surface Mode upon ascent to 2 FT (0.6 M) for 1 second; however, Surface mode
'screens' will not be available until a Transition time elapses.
The reason for this is that making a descent during the first 10 minutes after surfacing from a NORM or GAUG dive, or
the first 1 minute after surfacing from a FREE dive, is a continuation of that dive.
A descent made after the 10 minute (or 1 minute) interval has elapsed is then considered a new dive.
During the first 10 minutes after surfacing from a NORM or GAUG dive, or the first 1 minute after surfacing from a FREE
dive, the Dive Main screen will be displayed with Surface Interval time replacing Current Depth. Dive ALTs can be accessed
to view other information pertaining to that dive.
POWER SAVER MODE (PSM)
Once 10 minutes elapse, after the 10 minute (NORM or GAUG) or 1 minute (FREE) Transition Period on the surface after a
dive, the unit will enter a Power Saver Mode (PSM) which turns the display screen off until a button is pressed at which time
it will turn back on.
During the 10 minutes that the screen is off, all operations continue as normal in the background with current updated infor-
mation displayed as soon as the screen comes on again.
