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. It then switches to
the Reply Mode and transmits a series of pulses. These pulses will appear on the
interrogating radar display as a series of arcs leading away from the SART‘s position. Both
SART lights flash rapidly and the buzzer emits a pulsed sound (beep) at about one second
interval indicating the Reply Mode. 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 pack 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.

1. The Pathfinder
TM

is supplied with a telescopic pole to raise the SART one meter above
sea level.
2. To operate, simply turn the bottom cap of the SART to release the pole.
3. Pull the pole downward and extend it to its maximum length.
4. To lock pole in position pull firmly across pole joints while twisting slightly.
5. Tie Lanyard to life raft to allow retrieval should the SART fall into the water.
6. Push SART through life raft observation port and place foot of pole in pocket at base of
life raft.
7. Use life raft ties to hold SART pole near vertical.
8. Ensure SART is not obscured by metal objects or inflatable Radar reflectors.
9. Periodically check to see if SART is still vertical.
