7.5 Radar Transponder (SART) Screen
Display
SART is life-saving equipment that was approved by GMDSS and is used for detecting positions of
survivors who suffer from distress accidents. SART, which operates under the frequency band of 9GHz,
receives a radar wave of 9GHz that is launched from the radar of the rescue boat or plane and
generates a series of response signals to notify the accident position to the searchers.
Set the equipment to the following in order to receive SART signals. Use the settings for SART
reception for detecting beacons and target enhancers also.

Set the range scale to [6NM] or [12NM] by using the Range Scale button on the RADAR

Memo
