Replacing 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.
