GMDSS. FCC Test 25

Why is it important to limit the duration of testing a SART?

To prevent overheating, a SART requires sufficient ventilation that is significantly reduced when the SART is being tested.
Testing a SART should be performed only in controlled environment as a test signal may be misinterpreted as a genuine distress situation.
If another SART is testing at the same time, the two signals will cause damage to the unit that transmitted them.
Excessive testing causes 'burn in' on the vessel's radar PPI.

What statement is true regarding tests and maintenance that could be provided for the SART?

Battery should be replaced with a new one before the manufacturer's expiration date shown on the SART.
Extreme care should be exercise because testing of the SART may be received by other vessels and may be interpreted as a distress condition or provide interfere with other vessels' safe navigation.
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.
All of these.

Which statement is true regarding the SART required for GMDSS compliance?

This is a performance monitor attached to at least one X-band navigational radar system.
This is a performance monitor attached to at least one X-band navigational radar system.
This is a 9 GHz transponder capable of being received by another vessel's S-band navigational radar system.
This is a 9 GHz transponder capable of being received by vessel's X-band navigational radar system.

Which statement is NOT true regarding the SART?

Why should functional testing of an SART be minimized?

Which of the following would most likely prevent a SART's signal from being detected?

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.

Which statement is NOT true regarding the SART?

Responds to interrogations by a vessel's X-Band radar.
This is a 6 GHz transponder capable of being received by a vessel's X-band navigational radar system.
This is a 9 GHz transponder capable of being received by another vessel's X-band navigational radar system.
Transmits a distinctive signal for easy recognition.
