What to do if the red error indicator is flashing on my Em-Trak Transceiver?
- A
  Andrew Carter PhDSep 2, 2025
  If the red error indicator is flashing on your Em-Trak Transceiver, it may indicate a problem with the VHF antenna system. You can confirm this using proAIS2. If the 'High VSWR' alarm is active, check for a faulty VHF antenna, cable, or connectors, a poor connection at the VHF antenna/cable/connectors, the suitability of the VHF antenna (antennas tuned to 162MHz are recommended for AIS only, while antennas tuned to 159MHz are recommended for splitter variants), and the VHF antenna location (ensure it isn't mounted near other transmitting antennas, sources of interference, metal structures, or other obstructions).

  If the red 'error' indicator is illuminated on your Em-Trak Transceiver, first check that the unit is programmed with a valid MMSI number using the Configuration tab in proAIS2. Next, ensure that the GNSS antenna has a stable position fix, which can be confirmed in the GNSS Status tab of proAIS2. Finally, verify that the power supply is within 12 - 24V using the Diagnostics tab of proAIS2.

How to fix amber LED indicator flashing continuously on Em-Trak Transceiver?
- J
  James Watson DDSAug 26, 2025
  The amber LED indicator flashes while the transceiver searches for a position fix. If it takes longer than a minute, check the performance of the GPS antenna by using the GPS Status tab of proAIS2.

What to do if no data is being received by the chart plotter from my Em-Trak B953 Transceiver?
- G
  Glenn WilliamsAug 25, 2025
  If no data is being received by the chart plotter, check that the signal wires are connected correctly and that the baud rate matches on both the transceiver and the chart plotter. Also, confirm that other vessels are within radio range and that they are displayed on the Other Vessels tab of proAIS2.
