7.5Replacing the Fuse

The fuse (12 VDC: 10A, 24 VDC: 5A) in the power cable protects the communications unit from overcurrent and reverse polarity. If the fuse blows, find out the case before replacing it. If it blows again after replacement, contact your dealer for advice. Be sure to use the correct fuse. Use of a wrong will damage the equipment and void the warranty.

CAUTION

Use the proper fuse.

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