[CA] [CA11] AIS error message

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum newrule,

It is recommended that you verify that your AIS650 has been updated with the latest available Raymarine product software update, as early software for the AIS650 would trigger VSWR related alarms with antenna/cable assemblies which produced VSWR levels which were within normal ranges. Should the AIS650's software not be current or should you not know, then it would be recommended that the AIS650's software be updated to address this issue. If operating with the latest AIS650 software and should the problem persist, then it would be recommended that the VHF antenna, antenna cable assembly(s), and splitter (if any) be tested to ensure that the measured VSWR is less than that specified within the related FAQ found here. Should the measured VSWR not exceed the value specified within the referenced FAQ, then it would be recommended that the AIS650 be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
