Signal Jrc Radar — No Sync

For any vessel operator, from coastal freighters to ocean-going tankers, the radar is the primary source of collision avoidance and navigation safety. JRC (Japan Radio Co.) radars, known for their ruggedness and reliability, are a staple in the wheelhouse. However, even the most robust systems encounter faults. One of the most cryptic and frustrating alerts a technician faces is the error on a JRC Radar display.
