No Sync Signal Jrc Radar __top__ Instant

The (often called the Trigger or TX Gate) is a short electrical pulse generated by the display unit and sent up to the scanner via the signal cable. This pulse tells the magnetron exactly when to fire. After firing, the scanner sends back the video echo signal. The "No Sync Signal" error means the display unit has stopped receiving the return confirmation that the trigger was received, or the loop is broken.

Check the cable junction box and the display unit's rear ports for corrosion. Unplug and reseat the scanner connector. no sync signal jrc radar
