a known distress position should use their radar on the 12-mile range for
the initial SART detection, reducing the scale to (j miles as they approach
the SART position.
Routine maintenance and checks
The main check of the SART is the monthly security/performance
check. For the performance check, someone has to be standing at the
radar screen. On smaller vessels the person testing the SART can do
this, to observe the transmission.
All SARTs have a test switch/button. After checking the
manufacturer's instructions, operate the test switch/button either in the
wheelhouse, or on the bridge wing or other location where the radar
signal can be detected. Your radar will cause the SART to start
transmitting. The SART itself should display a light and issue an audible
alarm.
The radar screen should be covered in concentric circles, your
vessel and the SART location being the same. Only run the test for the
short period required to observe the test, or other vessels in the vicinity
may think that someone really is in trouble.
If the test is being performed by two persons - one on the bridge
and the other out of voice contact - use hand-held VHF radio to
keep in contact and to ensure that the test does not last any longer
than necessary.
Check also that the battery is still in date and is not likely to expire
in the near future, otherwise you should make arrangements for a
replacement at your next port of call.
