AIR INTEGRATION (AI)

The Swift connects to Shearwater dive computers to provide air integration capability.
Al stands for Air Integration. This refers to a system that uses wireless transmitters to measure the gas pressure in a scuba tank and transmit this information to the dive computer for display and logging. Data is transmitted using low-frequency (38kHz) radio communications. A receiver in the dive computer accepts this data and formats it for display. The communication is from the transmitter to the computer without requiring a response. Two (or more) dive computers may be programmed to receive the same transmitter(s).
Although the feature is named “Air” Integration, other gas mixtures can be used with the system as well. When using gas mixtures with oxygen content above 22%, be sure to have proper training on such mixtures, and follow proper cleaning and material compatibility guidelines. Swift transmitters are built with 02 compatible materials.

NOTE FOR COMPATIBLE PRESSURE MEASUREMENT WIRELESS TRANSMITTERS
A component of self-contained breathing apparatus as defined by EN250:2014 is Pressure Indicator, intended for use with air only. Products marked EN250 is intended for use with air only. Products marked EN13949 is intended for use with gases containing more than 22% oxygen and must not be used for air. Installing the transmitter
Before using the Al system, you will need to install one or more transmitters on the HP (high pressure) port of the scuba tank first stage regulator. Use a first-stage regulator with at least two HP ports, so that a backup submersible pressure gauge (SPG) can be used. Installation torque should be hand­ tightened to snug, excessive force is not required. An 11/16″ or 17mm wrench may be used if desired.

Position the transmitter such that it is on the same side of your body as you wear the dive computer. The range is limited to approximately 3ft (1m).
A high-pressure hose may be used to relocate the transmitter for better reception or convenience. Use hoses rated for a working pressure of 4500psi (300bar) or higher. If using a hose the use of a ‘spool’ insert is required (not included). In this case, the spool holds the air pressure and the transmitter base o-ring prevents water ingress to the hose fitting threads.

Always use a backup pressure gauge
Historically, wireless gas pressure transmitters have been reliable. However, like all other electromechanical systems, they will eventually fail. When this happens, they might report a higher or lower gas pressure than remaining a SCUBA cylinder or they may report no pressure at all.

USE A BACKUP ANALOG SPG
Always use a backup analog submersible pressure gauge as a redundant source of gas pressure information.

Unlike a mechanical pressure gauge, the failure of a transmitter will normally produce error messages on the attached dive computer. However, there could be failures that produce no error messages and result in a sudden unexpected out of gas emergency that every diver must be prepared to manage.

Shearwater recommends using a backup submersible pressure gauge (SPG) as a redundant source of gas pressure information and regularly confirming the agreement of the gas pressure reading of the SPG and wireless transmitter.

Turn on the Transmitter
Turn on the transmitter by opening the tank valve. The transmitter will automatically wake up when it detects pressure over 7 bar (lOOpsi). Pressure data is transmitted approximately every 5 seconds.

LED Indicator

The LED indicator on the top of the Swift will flash green when a transmission is sent. This helps to indicate that the transmitter is operating properly.
The LED will flash red if an interfering signal is detected. The Swift will try to transmit again when the channel is free.

Setting up Al on the Dive Computer

• Enable Al on the dive computer
• Pair the Swift transmitter
• Configure Al display on the home screen

Refer to the dive computer manual for details on setting up the Al system.

Pairing the Transmitter
Each transmitter has a six-digit serial number etched on its body. Al communications are coded with this number so that the source of each pressure reading can be identified. Enter the six-digit serial number (including any leading zeros) into the transmitter serial number setting of the dive computer menu.
Enter the rated (full tank) pressure value as well as desired reserve pressure level.

Turning off the Transmitter
To turn off the transmitter, close the tank valve and purge the second stage regulator to drain pressure from the hoses. The transmitter will automatically power down after 1 minute of no applied pressure (less than 3.5 bar or 50 psi).

Purge Air from regulator when not in use
We recommend purging the air from the regulator when the system is not in use. This extends the battery life of the transmitter (as it will continue transmitting any time there is the air pressure in the regulator system), as well as lowers the risk that a diver might enter the water with the air pressure turned off. Please ensure the air is turned back on before donning the gear.

CHECK THAT YOUR TANK VALVE IS OPEN
Always take a few breaths from your regulator or purge your regulator’s second stage while monitoring your tank pressure for a full 10-15 seconds prior to entering the water to ensure your tank valve is turned on.
If the first stage regulator is charged but the tank valve has been closed, the breathing gas available to the diver will decrease rapidly and within a few breaths, the diver will face an “out of air” situation. Unlike an analog gauge, the air pressure reported on the dive computer will only update every 5 seconds, so the pressure must be monitored for longer than that (we suggest 10-15 seconds) to ensure the tank valve is open.
Including a regulator purge test followed by 10-15 seconds of air pressure monitoring before entering the water as part of your pre-dive safety check is a good way to mitigate this risk.

Using Multiple Transmitters
The Swift is designed with the use of multiple transmitters. The transmit interval of each transmitter varies within a 4.8 to 5.2 second time period and each Swift includes a receiver used to check for other transmitters and avoid colliding with their data. Four or more transmitters may be used simultaneously, without the need to use multiple transmitter types (colors used on legacy Shearwater transmitters).
It is important to ensure the transmitter identification displayed on the dive computer matches the tank the transmitter is attached to.
It may be useful to apply identifying paint or tape to transmitters if using multiple units.
Legacy Shearwater transmitters may be used with the Swift in multiple transmitter configurations, although the maximum should be two (one grey, one yellow). Best results will be obtained by using all Swift transmitters, as the legacy transmitters do not avoid collisions and will increase the amount of lost data.
Using Swift with other brand dive computers
Swift transmitters may be used with other brands of dive computers that are compatible with Shearwater transmitters. However, this operation cannot be guaranteed.

CHANGING THE BATTERY

Remove the cover
Using the hex screwdriver provided, loosen and remove the 4 screws at the base of the transmitter.
Grasp the cover and pull away from the base. This operation may be easier if the transmitter remains attached to the HP port of a regulator. Ensure no pressure is present at the HP port during the battery change operation.

Exchange the battery
Remove the existing battery from the battery clip.
Dispose of the battery properly according to local regulations.
It is recommended to leave the battery out for at least 1 minute to allow internal circuits to reset.
Insert a new battery, negative towards the base, positive towards the top (a small + is marked at the top end). Push the battery down gently into the clip. The status LED sequence red, yellow, green shows good battery contact.

Replace the cover
Ensure the base o-rings are clear of debris and are not damaged. Replace o­ rings (see specifications page for dimensions) if damaged, using a small amount of O2-compatible lube. Carefully align the cover so the circuit board fits in the wide part of the case. The cover should slide down easily until the base o-rings engage. Do not force the cover down if it is not aligned. Press the cover down firmly until the screw holes line up with those in the base.
Using the hex screwdriver provided, replace the 4 screws and tighten them to snug.

Check Transmitter Operation
To ensure the new battery is installed properly and the Swift is working, install the regulator on a scuba tank and pressurize the system. Check that the pressure reading is reporting correctly.

LED Indicator
Normal transmit operation shows a quick green flash upon transmitting. A red flash indicates a detected collision, and if followed by a green flash this indicates the transmission was successfully delayed. Occasional red flashes when transmitting are not normally a cause for concern. Consistent red flashes at transmitting intervals indicate strong interference, and this should be resolved for best results from the Swift transmitter. Repeating red flashing after battery change indicates a self-test failure – this could be due to a bad battery or other internal problem – do not dive the unit if continuously flashing red.

TROUBLESHOOTING

Battery life is short
Many divers will find the battery will last several years before requiring replacement. However, frequent use with long dive times or leaving the regulator charged when not diving could drain the battery more quickly.
Ensure the regulator is purged when not in use. The Swift will continue to transmit if gas pressure is above 3.5 bar (50 psi). Ensure the use of a good battery. Counterfeit batteries are sometimes a problem. Test the battery with a load if unsure.

Battery warning levels (test with a lmA load)
2.75V yellow (low) battery warning.
2.50V red (critical) battery warning.

Frequently dropped signals
The range is limited to about lm and may be affected by the alignment of the transmitter or receiver. Try to reposition the transmitter closer to the receiver or change its orientation so that it ‘points’ (body aligned towards) the receiver. A small HP hose may be useful for this purpose (if a hose is used, ensure a ‘spool’ is used on the inner diameter of the hose to transmitter coupling).

Interference
It is possible for high-energy lights, scooters, or heated undergarments to generate interference in the RF frequencies used by the Swift transmitter.
This can be checked by turning those devices off for 10-15 seconds to see if the signal returns. Keep interference generating devices away from the dive computers (the receivers are the most sensitive to interference) as much as possible.

STORAGE AND MAINTENANCENCE

• The Swift should be stored dry and clean. The battery may be left installed if desired.
• Do not allow salt deposits to build upon your Swift. Rinse in freshwater to remove salt and other contaminants. Allow drying naturally before storing.
• Clean with water ONLY. Any solvents may damage the transmitter.
• Clean only when installed on a regulator. Do not allow water or other debris to enter the high-pressure port.
