Turn on the 12V or 24v power to the SPL2000.
Ensure the VHF radio and Class B AIS Transponder are turned on.
Verify that the green
“POWER”
LED indicator on the front of the unit is illuminated,
Listen to channel 16 or another VHF channel and confirm that you can hear voice communication.
Press the PTT button on your VHF and ensure that the Yellow
“VHF”
LED indicator on the front of the unit
illuminates whilst the PTT button is pressed.
Watching the Yellow
“AIS”
LED, ensure that at regular 3 minute intervals or 30 second intervals if you are
underway (SOG > 2 Knots), the Yellow
“AIS”
LED briefly illuminates when the AIS Transponder transmits its
position.
If your Class B AIS Transponder was supplied with configuration/diagnostics software like proAIS, run this
software and check that the Power (SWR) readings are still within the acceptable value range.
Installation is now complete.
