  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.
