7R-A-30: SART: Testing Procedures & Battery Parameters

7R-30E1: Which of the following statements concerning testing and maintenance of SARTs is true?

Testing a SART should be performed only in controlled environment as a test signal may be misinterpreted as a genuine Distress situation.

An at-sea GMDSS maintainer is not able to test a SART as it is hermetically sealed.

A SART's battery must be replaced within ninety (90) days after the expiration date imprinted on the unit.

All of the above.

7R-30E2: Why is it important to limit the duration of testing a SART?

Testing a SART should be performed only in a controlled environment, as a test signal may be misinterpreted as a genuine Distress situation.

Excessive testing causes "burn in" on the vessel's radar PPI.

To prevent overheating, a SART requires sufficient ventilation that is significantly reduced when the SART is being tested.

If another SART is testing at the same time, the two signals will cause damage to the unit that transmitted them.

7R-30E3: What statement is true regarding tests and maintenance that could be provided for the SART?

All of these

To fully verify operation within manufacturer's specifications would require measuring equipment to generate 9 GHz signals; generally beyond the scope of on-board maintenance.

Extreme care should be exercised because testing of the SART may be received by other vessels, and may be interpreted as a Distress condition, or it may interfere with other vessels' safe navigation.

Battery should be replaced with a new one before the manufacturer's expiration date shown on the SART.

7R-30E4: Why should functional testing of a SART be minimized?

All of these

Potential interference with safe navigation.

Minimize power consumption of the battery.

Possibility of misinterpretation by other vessels as a Distress situation.

7R-30E5: Which is not a valid maintenance and testing function for a SART?

Operational test with several vessels to determine effective transmitting range.

Inspection of container for apparent damage.

Inspect battery expiration date and the lanyard condition.

Brief operational test utilizing own ship's radar.

7R-30E6: The SART is required to have sufficient battery capacity to operate in the stand-by mode for what period of time?

Four days

Eight hours

Three days

Forty-eight hours
