6. MAINTENANCE & TROUBLESHOOTING

6.2Fuse Replacement

A fuse is in the fuse holder on the power cable and inside the power supply unit, and they protect the equipment from reverse polarity of the ship's mains and equipment fault. If a fuse blows, find out the cause before replacing it. Use the correct fuse. Using the wrong fuse will damage the equipment and void the warranty.

WARNING

Use the proper fuse.

Use of a wrong fuse can result in damage to the equipment or cause fire.
