SELF-TEST
It is recommended to self-test the SR500 every six months. A test transmission is sent that is visible to all AIS (automatic
Identification system) users in range. Testing success depends on the GNSS position acquisition. Testing must be carried
out in the open and under an unobstructed sky.
In test mode, the SR500 transmits a unique 9-digit digital ID number and the latitude and longitude coordinates. The AIS
receiver shows “SART TEST” when the SR500 is transmitting in test mode. If the SR500 is transmitting in active mode the
AIS receiver shows “SART ACTIVE”.
Remove the SR500 from the carry bag and fit the device onto the mounting pole. Hold the SR500 up in clear view of the sky
to maximise GNSS position acquisition.
To begin the self-test, press and hold the “TEST” button for three seconds. The LED flashes green or amber. The LED should
flash green within two minutes of the GPS/GNSS position being fixed. If it takes longer than five minutes for the LED to
flash green the position may not be fixed. Move to a new location that has a clearer view of the sky to obtain a better
result.
Note:
If the LED flashes amber the SR500 has already previously been activated or self-tested more than the maximum 100 times.
