PATENT NOTICE

U.S. Patents have been issued, or applied for, to protect the following design features:

Dive Computer with Free Dive Mode and Wireless Data Transmission (U.S. Patent no. 7,797,124), Dive Computer with Free Dive Mode (U.S. Patent no. 8,600,701), and Air Time Remaining (U.S. Patent no. 6,543,444). Other patents pending. User Setable Display (U.S. Patent no. 5,845,235) is owned by Suunto Oy Finland.

DECOMPRESSION MODEL

The programs within the VTX simulate the absorption of nitrogen into the body by using a mathematical model. This model is merely a way to apply a limited set of data to a large range of experiences. The VTX dive computer model is based upon the latest research and experiments in decompression theory.

Still, using the VTX, just as using the U.S. Navy (or other) No Decompression Tables, is no guarantee of avoiding decompression sickness, i.e. “the bends.” Every diver’s physiology is different, and can even vary from day to day. No machine can predict how your body will react to a particular dive profile.

•An Oceanic welcome screen will be displayed for 3 seconds (Fig. 2)* during which diagnostics will be performed verifying that sensors and battery voltage are within tolerance.

*After the Battery is replaced on a new day prior to performing any dives, a message is displayed before the welcome.

•It will also check ambient barometric pressure, and calibrate present depth as 0. When at 3001 feet (916 meters), or higher, it will adjust depth for the higher altitude.

•After the diagnostic check, the Home Menu screen will be displayed (Fig. 3) allowing you to select what you would like to do (view information, perform setup, access operating modes).

•If no button is pressed within 2 minutes, the unit will enter PSM (Power Saver Mode) turning the screen off. Refer to page 8.

•If no dive is made within 2 hours, the unit will shut Off.

Wet activation contacts will automatically activate the unit and cause it to enter dive mode when the contacts become wet and it senses depth of 5 FT (1.5 M). They will not inadvertently activate Surface Mode such as when in a wet gear bag.

MENU SYSTEM

The viewing area is used to display alpha numeric messages and measured values as well as menu type systems for selection of settings and various auxiliary functions. It also serves as the Digital Compass.

Menus which are identified by function such as Main, Set, and Switch. The items available within the menus vary according to the mode you are in at the time. Some settings, such as for Units, are common throughout the modes and can be changed in any Utilities Menu.

To access, while viewing the Home Menu when on the surface >>

•S (< 2 sec) to access Home Setup Menu, then -

•A or M (< 2 sec) until BATT, TMT STATUS is highlighted (Fig. 5).

•S (< 2 sec) then activates the unit's receiver displaying a Please Wait message (Fig. 6A) for 3 seconds, then the Status screen appears (Fig. 6B).

A color coded Low Battery icon is displayed at the lower/left of Surface and Dive Main screens when battery power is low.

•No icon = means battery power is good and you have sufficient power to conduct normal diving activities.

•Yellow = caution (warning), meaning you should have sufficient battery power to complete a normal 1 hour dive.

•Red (while on the surface) = alarm, meaning the battery must be changed prior to starting a dive.

•Red (during a dive) = alarm, meaning you should savely ascend to the surface and replace the battery before continuing with diving activities. Caution - The unit may shut off at any time without further warning.

LOW BATTERY WARNING

•The Battery icon will be displayed (yellow) when voltage decreases to 2.75 vdc.

•Battery change prior to any diving is recommended. Less than 1 hour dive time may be expected.

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.

VTX OPERATING MANUAL

BLUETOOTH

The VTX contains a Bluetooth module that can be paired with a PC, Mac, or mobile device.

Bluetooth is initialized while the selection is highlighted on the Home Setup Menu (by S < 2 sec).

A Please Wait screen (Fig. 19A) will be displayed for 5 seconds followed by a screen displaying a countdown from 120 to 0 seconds (Fig. 19B).

If Bluetooth fails to initialize, a message will be displayed for 3 seconds instead of the countdown (Fig. 19C), then operation will revert to the Home Setup Menu.

During the countdown, the unit is on allowing it to be paired with other Bluetooth devices.

> Mobile devices require Diverlog for Mac software that contains files required to discover and communicate with the Bluetooth chip in the VTX. Likewise, laptops and desktops are only able to discover the VTX through Diverlog for Mac or the OceanLog PC Interface program with the use of an optional dongle that can be obtained from an Oceanic Dealer.

> Once paired, a connected message is displayed (Fig. 19D) with the signal icons <<<< changing from white to green while the Download, Upload, or Firmware Update operation is started.

> Once the VTX is unpaired from the PC, Mac, or mobile device, it will be necessary to pair/connect it through the software before every download/upload.

> Pairing/connecting is not permanent and needs to be reestablished every time.

> This connection functions the same way the USB does in the Diverlog and OceanLog programs.

> If the 2 minute countdown elapses without action, operation will revert to the Home Setup Menu and the connection request of the OceanLog, Diverlog, or iPhone/iPad version software will be cancelled.

> If the connection is cut using the software, operation will revert to the Home Setup Menu.

While downloading data, uploading settings, and updating firmware, corresponding screens are displayed indicating action in progress (Fig. 19E, 19F, 19G).

PDPS (Pre Dive Planning Sequence)

Plan screens will sequence through Depths from 30 to 190 FT (9 to 57 M), or the Max Depth that will allow theoretical No Deco Dive Time of at least 1 minute based upon the previous dive profiles in a series of repetitive dives and taking into account descent and ascent rates of 60 FPM (18 MPM).

When the Conservative Factor is set On, NDLs are reduced to the values of the next 3,000 foot (915 meter) higher Altitude. Refer to tables in back.

>Internally, the unit will keep track of the oxygen accumulation so that if FO2 for Gas 1 is subsequently set for Nitrox, the oxygen accumulated during previous AIR dives will be accounted for in the next Nitrox dive (during that dive period and series of repetitive dives).

FO2 set for Nitrox:

>When FO2 for any Gas is set for Nitrox (21 to 100%), the dive is calculated to be for Nitrox.

>Once FO2 for Gas 1 is set for Nitrox (21 to 100%), the AIR option for all gases is disabled until 24 hours elapse after the last dive.

> The AIR option will not be displayed in Set Gas until a full 24 hour Surface Interval has elapsed.

•A (hold) - to scroll upward through the FO2 set points at a rate of 8 per second stopping momentarily at 32%, 50%, 80%,

and 100%, then at AIR or 21%.

•M (< 2 sec) - to step down through FO2 set points one at a time.

•S (< 2 sec) - to save the FO2 setting and highlight & flash the PO2 digits if Nitrox, or move to GAS 2 if AIR.

•S (2 sec) - to step back to & highlight the GAS # selected without changing the FO2 setting.

When the PO2 alarm digits are highlighted & flashing (Fig. 28C):

•A (< 2 sec) - to step up through the set points one at a time from 1.00 to 1.60 in increments of 0.05.

•M (< 2 sec) - to step down through the set points one at a time.

•S (< 2 sec) - to save the PO2 Alarm setting and step back to & highlight the GAS # selected.

•S (2 sec) - to step back to & highlight the FO2 value without changing the PO2 setting.

FO2 & PO2 Alarms for all gases will remain at their respective set points until changed.
