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 approximately one
second, the SART goes into 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 approximately one- second intervals
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 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
Remove the SART from the bracket. Activation of the SART is completed by
using the three-position switch ring (TEST-OFF-ON), as shown in Figure 5.
1. 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. The SART will beep once and flash every four seconds
ii. The flashing red light indicates the SART is ON
4. Turn the bottom cap of the SART and deploy the telescopic pole to its
maximum length of 3 ft. (1 meter).
5.
