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 the red
light 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.
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.
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.
The SART must only be used in situations of Grave
and Imminent Danger.
