  If your JRC Marine Equipment isn't powering on, several issues could be at fault. First, make sure the ship junction box is supplying power and that the cabling is correctly connected. If you're using optional power supply equipment (only MID), verify its cabling as well. Also, inspect the fuse connected to the power cable and the fuse in the optional power supply equipment (only MID); replace them if necessary, assuming the cabling is normal. For LOG models, check the connection. If none of these steps resolve the issue, the display unit switch may be broken.

  If your JRC Marine Equipment isn't powering on, first ensure the ship junction box is supplying power by checking the cabling. Also, if applicable, verify the power supply unit cabling is correctly connected (only MID models). If the cabling is fine, inspect and replace the fuse connected to the power cable or the power supply equipment fuse (only MID models) if blown. For LOG models, check the connection. If problems persist, the display unit switch may be broken, and you should consult with JRC or their agents.
