SHIELD DISPLAY (for Neptune series masks)
Depth and Air Pressure automatic analogic built-in display.

To check important data (depth and air pressure) while diving, a diver must look at his or her wrist or console display instruments. With the SHIELD DISPLAY this information is brought directly to the mask's face shield, improving diver comfort and efficiency.

The SHIELD DISPLAY is an accessory available for installation on any Neptune Space, Neptune II NIRA, Neptune II or previous models of Ocean REEF full face or integrated diving masks.

It consists of the following components:

	2 LED displays, inside the face shield (depth displayed on the right and tank pressure displayed on the left), connected to the mask through the regulator/octopus port
	Supplied with a quick connector, the main electronic unit mounts easily to the tank strap of the BC.
	The high pressure hose from the regulator first stage plugs into the main unit, which also has a depth sensor.
	The newly designed "surface air valve" allows the connection of the Shield Display through this valve, but still allows the diver to breathe surface air through the valve as well, thereby conserving compressed gas. This valve is now referred to as the "electronic connection surface air valve".

The LED may be turned off and on during the dive by pressing the button on the Shield Display's quick connection. It will turn on automatically if the tank pressure is low and/or the depth is 40 meters (120 feet) or greater.

Air Pressure
The air pressure display has two sets of LED. No digital information is provided. When the tank is full, all displays show green. As pressure decreases, the LED at the top turn off. As the air pressure approaches 60 bar/900 psi the lights become red, and when the air pressure reaches 50 bar/700 psi the red L ED flashes.

Depth
At the beginning of the dive, only the reference bar turns on to indicate the unit is working and displays a depth of 50 meters/164 feet. As the diver descends past 5 meters/15 feet the LED lights as the diver descents past the corresponding depth. At 45 meters/148 feet the L ED turns red. At 50 meters/164 feet the LED red light flashes.

	Powered by 12v 2,2Ah rechargeable lead battery

	Low battery autonomy (after alarm starts) 30 minutes
	Stand by power 2.5 mA
	Battery charging time (w/enclosed charger) 9 hours
	Depth/pressure tolerance ±2%
	Depth sensor - max pressure 8 bar/116 PSI (70 meters/230 feet)
	HP Air pressure sensor - max applicable pressure 450 bar / 6500 psi
	Start up Automatic (wet contacts)
	Turn off Automatic
	Alarms: Low battery, Depth > 50 mt/165 feet, Low on air, Unit not working
	Weight (dry) 5 kg /3.3 lbs
	LP hose with quick connection enclosed
	Charger enclosed

It is important to remember that the SHIELD DISPLAY is a support system and it is NOT an alternative to the conventional pressure and depth gauges, or computers. The SHIELD DISPLAY provides information at a glance, whichallows the diver to quickly evaluate the general conditions (air supply and depth) of his or her dive.

How to use the simulator
Please click on, NeptuneII.exe, the program will open with a graphic of the Neptune II NIRA mask, viewed from the inside, underwater, and with the Shield Display LEDs, already fixed on the visor.
You will be viewing some beautiful Coral Reef fish.

1. Choose "english"
You may now choose, to manually adjust the "Tank Pressure" and/or "Depth," or choose to activate the "Simulation." To use the Manual mode, simply have the simulation option, "OFF."

2. AIR PRESSU RE ADJUSTMENT
By using your cursor, you may increase or decrease the pressure in the tank. You may read the Tank Pressure, in the center window, while you see which LEDs, will turn "On" or "Off".

3. DEPTH ADJUSTMENT
By using your cursor, you may increase or decrease the depth. You may read the depth, in the center window, while you see which L EDs, will turn "On" or "Off".

4. You may change the Brightness of the LEDs, in the bottom left window, by moving the cursor from left to right.

5. You may turn off the LEDs in the bottom window, 3rd from the left. You will see that if the Shield Display is in alarm mode (too deep or low pressure tank) the LEDs will NOT turn off and they will turn on automatically if you are going too deep or you are in a low pressure situation.

6. You may also view what happens when the battery is low, by activating "Low Power" at the bottom of the screen.

7. After all manual possibilities have been viewed, you may then activate the "Automatic Simulation". This feature is installed to check that your unit is working properly before your dive. To activate, just click "On", on the simulator. It will automatically activate the program, you will then be able to see what kinds of alarms are available during a dive.
