Why should functional testing of a SART be minimized?

Potential interference with safe navigation, notifying other vessels of an actual Distress and minimize power consumption.

Minimize power consumption of the battery and only test at sea to reduce potential interference or confusion.

Possibility of misinterpretation by other vessels as a Distress situation and only test in port to prevent potential interference with safe navigation or at-sea vessels.

Potential interference with safe navigation, possible misinterpretation of an actual Distress, minimizes draining the battery.
