VTX OPERATING MANUAL

OPERATING MODES
HOME >> This is a base mode that provides access to general items common to the operating dive modes.
NORM >> This is an operating dive mode used for Air and Nitrox scuba activity with up to 4 gases and transmitters.
If no previous dive has been taken within the past 24 hours, NORM is the default mode upon activation with others accessed as described later.
GAUG >> This is an operating dive mode used for scuba activity with up to 4 transmitters but without Ni-O2 calculations.
Once a GAUG dive has been conducted, operation locks into this mode for 24 hours.
FREE >> This is an operating dive mode used for breath hold diving activity with depth/time indication.
Ni-O2 calculations are performed while in FREE mode and are carried over between NORM and FREE.
COMPASS >> This is the navigation mode that can be used at any time while on the surface and during dives.
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 a Low Battery Alarm condition is present, BATT icon is red, entry into Dive Modes is blocked.
Operation shifts from Dive Mode to Surface Mode upon ascent to 2 FT (0.6 M) for 1 second; however, most 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 during the first 1 minute after
surfacing from a FREE dive, is a continuation of that same 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.
