Why is the red 'error' indicator illuminated on my Simrad Transceiver?

The red 'error' indicator on your Simrad Transceiver might light up for several reasons. It could be due to the unit not having a valid MMSI, so ensure your AIS transceiver is correctly configured. Another cause might be a faulty VHF antenna; check its connection and condition. Also, verify that the power supply is within the range of 9.6 V to 31.2 V. A lack of GPS position fix could also trigger the error; in that case, inspect the external GPS antenna's connection and installation, and review the GPS signal strength in proAIS2. You can also check for error and alarm messages in proAIS2.
