Forward Congratulations and thank you for purchasing the ACR PathfinderTM3 Search and Rescue Transponder (SART). The combination of computer aided design; high quality raw materials and quality-controlled manufacturing produce a superior product. The Test Facility at ACR can reproduce some of the harshest environmental conditions known to man. This assures that the products we produce can stand up to the rigors found in a marine environment.

1.0 SART Overview The SART helps search and rescue services to quickly locate a life raft in the event of a rescue at sea. The SART can either be stowed in a life raft, or mounted next to emergency exits and then carried to the life raft in an emergency. During an emergency, simply switch the SART on. When a vessel or aircraft with marine X-band Radar comes within 5 to 7 nautical miles of the life raft, the SART generates a distinctive “distress” pattern on its Radar screen (See figure 1).
2.0 Introduction The SART is a Search and Rescue Transponder that provides location information to search radars operating in the X-band (9.2 – 9.5 GHz). Once activated the SART detects the radar signal of the search craft and sends a series of response pulses to the radar of the search craft that causes a series of 12 equally spaced arcs to appear on the radar display (see figure 1). The arcs indicate the direction to the SART location.

Approved for GMDSS use WARNING: Contains Lithium Battery To avoid possible fire, explosion, leakage or burn hazard, do not open, recharge, disassemble, heat above +70°C (+158°F) or incinerate. 3.0 Vessel name The SART label has a space where you should mark the vessel name (see Figure 3). This can be done as follows . . . Using an indelible pen With an indelible pen, you can write the vessel name directly onto the SART.
4.0 Life raft stowage The SART can either be stowed in a life raft or lifeboat or it can be installed next to an emergency exit for carriage to the life raft in an emergency. For life raft stowage the SART should be positioned for easy access in an emergency. If the SART is hidden from view then labels should be used to show its position. For inflatable life rafts the mounting bracket should be discarded to avoid the risk of damaging the life raft.
When activated the SART has three Modes of operation. These are: · Receive - waiting for a valid interrogation by a radar signal. · Reply - replying to a valid interrogation by a valid radar signal. · Test self-test sequence that checks both indicator lights and the buzzer. WARNING The SART must only be used in situations of Grave and Imminent Danger. Figure 4 9 Y1-03-0170 Rev.
6.0 Sequence of Operations The SART has primary and secondary indicating systems. The primary system is the indicator lights and the secondary system is the buzzer. When the switch is set to ON, the SART immediately enters the Test Mode. Here both red lights and the buzzer are tested. Note that in noisy environments it may be difficult to hear the buzzer. After about one second the SART goes to Receive Mode. The SART remains in the Receive Mode until it detects a radar pulse.

8.0 Hanging SART 1. If no pole is available, or if you prefer, you can suspend the SART from the canopy support using the provided lanyard. 2. Loop the lanyard over the canopy support and back through the holes located directly under the switch ring. Secure the lanyard with a knot to secure the SART in place. 3. The SART should be as high as possible and at least 1m above sea level. Ensure SART is not obscured by metal objects or inflatable Radar reflectors.
9.0 Vessel Mounting To deploy SART on board a distressed vessel, rather than a life raft, hang SART near vertical as high as possible, with a clear view of the horizon. The SART must not be obscured by metal bulkheads etc. Installation The SART should be mounted inside the vessel, next to an emergency exit. Some ships require 2 SARTs one by a port exit and one by a starboard exit. Mount each SART as follows . . . · Mount in plain view, at a convenient height, so that all crew can easily remove the SART.

10.0 Testing and Maintenance The SART is a safety device, it must be regularly checked at least every 2 months as follows. . . Visually inspect the casing for cracks & punctures. Extend the pole and check that it operates correctly, and then return the pole to its housing. Check to ensure the tether lanyard is neatly bundled and firmly secured to the SART. Ensure the lanyard is NOT tied to any part of the vessel.
11.0 Servicing If the SART fails any of its monthly checks, the SART must be returned to the supplier or an approved service agent for investigation and/or servicing. If the battery is beyond its expiry date, the SART must be returned to a Battery Replacement Center for a battery change. The battery is NOT user serviceable; DO NOT attempt to change it. If the SART has been used in an emergency or its integrity seal is broken, then the SART must be returned for a battery change.
