What is an SART?

A Search and Rescue Transponder (SART) may be triggered by any X-band (3 cm)
radar within a range of approximately 8 NM. Each radar pulse received causes it to
transmit a response which is swept repetitively across the complete radar frequency
band.

How to receive an SART

This radar is equipped with a feature that optimally sets up the radar for SART detec-
tion. This feature automatically detunes the radar receiver out of its best tuning condi-
tion. This erases or weakens all normal radar echoes, but the SART marks are not
erased because the SART response signal scans over all frequencies in the 9 GHz
band. When the radar approaches the SART in operation, the SART marks will en-
large to large arcs, blurring a large part of the screen.
1. Open the menu then select the [1 ECHO] menu.
2. Select [7 SART] (B type).
3. Select [ON].
4. Close the menu. The message "SART" appears in the message area when the
SART function is active.
When the SART is activated the radar controls are automatically set as follows.
