User manual ACR ELECTRONICS PATHFINDER 3

[. . . ] 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 the radar screen (see Figure 1). The ships radar signal guides the rescuers directly to the SART. Figure 1- Radar Distress Pattern A 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, which in turn causes a series of 12 equally spaced arcs to appear on the radar display (see Figure 1). The rescue craft follows the direction shown and proceeds to the SART. [. . . ] This sequence is repeated each time a radar signal interrogates or transmits a valid radar signal to the SART. When the radar signal interrogation stops, the SART automatically returns to the receive mode. With a fully charged battery the SART will operate in receive mode for a minimum of 96 hours. After this time period it will still respond to normal interrogation radar signals for an additional eight hours. Activation of the SART is completed by using the three-position switch ring (TEST-OFF-ON), as shown in Figure 5. Turn the blue activation switch ring to the left, placing the SART in test mode 2. Remove the red Pull Tab by pulling it down and completely out of the SART 3. Release the activation switch and guide it to the right until it is in the ON position i. Turn the bottom cap of the SART and deploy the telescopic pole to its maximum length of 3 ft. Remove lanyard and secure it to the life raft. Y1-03-0170G 7 When activated the SART has three modes of operation: Receive - waiting for a valid interrogation by a radar signal. Test - self-test sequence that checks both indicator lights and the buzzer. WARNING: The SART must only be activated in situations of grave and imminent danger. Figure 5 Y1-03-0170G 8 Pole Mounted SART 1. The PathFinderTM3 is supplied with a telescopic pole to raise the SART one meter above sea level (see figure 6). To operate, simply turn the bottom cap of the SART to release the pole. To lock pole in position pull firmly across pole joints while twisting slightly. Tie lanyard to life raft to allow retrieval should the SART fall into the water. Push SART through life raft observation port and place foot of pole in pocket at base of life raft. Ensure SART is not obscured by metal objects or inflatable radar reflectors. Periodically check to see if SART is still vertical. Figure 6 Y1-03-0170G 9 Hanging SART 1. If no pole is available, or if you prefer, you can suspend the SART from the canopy support using the additional lanyard loop provided (see Figure 7). Loop the lanyard through the support strap in the life raft and secure firmly. 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. Figure 7 Y1-03-0170G 10 SECTION 5 - MAINTENANCE This chart is a summary of the procedures described below.
